W elcome to the 

APS CentenniAl Meeting! 

We are thrilled to be here in Minneapolis-St. Paul to celebrate 

The American Phytopathological Society and honored to have a 

record number of past APS presidents and leaders here to help us 

commemorate our Centennial. 

The 2008 APS Centennial Meeting highlights the key developments 

and discoveries of our first 100 years and offers a dynamic look into 

the future of our science. You will have many remarkable opportunities 

over the next several days to participate in technical, societal, and 

social activities. We encourage you to take full advantage of your 

time here. Get involved on every level – attend social gatherings and 

networking events, visit historical and commemorative displays, meet 

the new generation of plant pathologists and researchers at the technical 

program, and participate in active and lively discussion with world-renowned scientists from our past, 

present, and future. 

This year’s program highlights historical and celebratory Centennial sessions with an expanded plenary 

session and a closing plenary luncheon featuring special guest speaker Dr. Lowell Catlett’s highly 

entertaining take on Tomorrow’s Agriculture – Six Trends You Can’t Afford to Miss! In addition, an 

informative technical program features symposia, over 350 oral and poster presentations, special flashand-dash 

presentations, and time with poster authors for discussion. There are more abstracts than last 

year, plus 27 special sessions covering today’s most interesting and relevant topics, including aflatoxins; 

biocontrol in organic crops; education, technology, and international collaboration in plant pathology; 

food security; new products and services; and much more. 

I would be remiss if I did not thank everyone for their contributions and willingness to work together 

in order to mark the occasion of APS’s first 100 years with this memorable tribute. Special kudos go to 

the Centennial Planning Committee, the many volunteers who donated to the historical pieces, and 

the Scientific Program Board (SPB) for their tireless efforts in forging all of the contributions into a 

program. 

Finally, this annual meeting represents a unique opportunity for us to come together, to share the 

work we are all doing individually and around the world, to learn from each other in a stimulating and 

challenging environment, and to celebrate all that went on before we were here. We are extremely proud 

of what we’ve become and the potential that exists for plant pathology thanks to the contributions of 

APS and its members.

Safety tips 

• Do not travel alone – stay in groups and travel in well-lit 

areas. Remove name badges when outside the hotels 

and convention center unless you are participating in a 

meeting event. 

• Do not give your room number out to anyone you do 

not know and avoid giving out your room number in 

conversations where strangers may hear you talking. 

• Bolt your hotel room door and only open when you 

know who is on the other side. (Note: hotel personnel 

wear uniforms and have identification badges. If 

in doubt, call hotel security to verify an employee’s 

identity.) 

• Do not leave your door ajar if you are going down the 

hall for ice or sodas. Someone may enter when you are 

not looking. 

• Know where the stairs are located in case of fire (do 

not use elevators). Also count the number of doors to 

the nearest exit in case you cannot see in a smoke-filled 

hallway. 

• Valuables, airline tickets, and money should be kept in a 

hotel safety deposit box or in a room safe, if available. 

procedures in Case of a Hotel Fire 

• Try to leave the hotel as quickly as possible. If you 

cannot, stay in your room and call the operator or 

security to let them know you are in your room. 

• Put your hand on the room door to see if it is hot before 

opening it. If it is, do not open quickly. Open it just a 

crack to see what is on the other side and be prepared to 

slam it shut quickly if necessary. 

• If you leave the room, take your room key with you! 

Shut your room door to keep smoke out. You may have 

to return if the exit is blocked. Remember the way back 

to your room as you go to the exit in case you need to 

return. 

• If necessary, drop to your knees to avoid smoke. Tie 

a wet towel around your nose and mouth to act as a 

smoke filter. Fold it into a triangle and put the corner in 

your mouth. 

• Do not take the elevator when you smell smoke or if 

you know that there is a fire in the building. 

emergency information 

Medical emergencies should be communicated to an APS 

staff member at the Registration Desk or an employee 

of the hotel where you are staying. In your hotel dial 

0 for operator or phone the local emergency response 

team by dialing 911 and give your exact location. At the 

Minneapolis Convention Center, use any house phone 

and dial “0” during an emergency. An Emergency Medical 

Technician (EMT) will be available during show hours 

at the Convention Center. Dialing “0” instead of 911 

at the Convention Center is the quickest way to receive 

assistance.

Centennial Sessions 

100 Years of The American Phytopathological Society 

Sunday, July 27 • 3:15 – 5:45 p.m. • Auditorium 

Over the past 100 years, APS has grown into a relevant and 

responsive leader in the field of plant pathology and has 

remained that way through a commitment to high standards 

and revolutionary leaders. Speakers will address the evolution 

of APS as a professional scientific society; the growth of 

APS as a publisher of journals and books; the role of APS in 

public service and education; APS leadership/cooperation in 

international agriculture and programs; and APS leadership in 

plant pathology within the life sciences. 

Plant Pathology in 1908/2008 

Monday, July 28 • 8:00 – 9:00 a.m. • 200 DE 

Plant pathology has come a long way in the century since APS 

was founded. Presentations from 1908 on phytobacteriology 

and chestnut blight will be followed by 2008 updates on 

these two topics to illustrate the progress of our science in 

the last 100 years. All speakers will be plant pathologists and 

presentations will be in 1908 costumes and with lantern slides! 

Optimizing Opportunities for Everyone in Plant Pathology 

Monday, July 28 • 3:15 – 6:15 p.m. • Auditorium 

It is more important than ever for our discipline to ensure 

opportunities for everyone and APS is taking steps to ensure 

that diversity is both valued and rewarded. Be a part of the 

discussion as well-known speakers address the history of 

women in plant pathology; how the quality of science benefits 

from diversity; and the impact of international scientists on 

scientific productivity. 

The Future of Plant Pathology 

Tuesday, July 29 • 2:45 – 5:45 p.m. • Auditorium 

The field of plant pathology is pushing forward with new and 

exciting technologies and applications. Powerful genomics 

and bioinformatics tools are enabling researchers to examine 

interactions among entire microbial communities, and new 

high-power computing capabilities are mining and comparing 

genomes and proteomes of plant pathogens and their hosts. 

CentenniAl PROgRAM 

APS is proud to offer many special activities at this year’s annual meeting 

in honor of our Centennial. 

Remote-sensing devices are being used to monitor plant 

disease epidemics across a wide range of temporal and spatial 

scales, and online databases are linking living plant pathogen 

culture collections to publicly available morphological and 

sequence data. Global food markets are demanding a reliable 

production of safe food and feed, and regulatory networks 

are poised to rapidly detect and respond to immediate threats 

of high-risk plant pathogens. A new “wired” generation of 

students needs to be engaged in the classroom. Attracting and 

retaining these individuals as agricultural professionals is a 

crucial discussion that must be explored in order to ensure the 

future of our discipline.

plenary Sessions 

Eight renowned speakers address the importance of agriculture 

and an efficient and secure food system in improving global 

public health. These topics are extremely relevant in today’s 

global society and this diverse gathering of industry leaders will 

cover many new and exciting approaches in our discipline. 

“Agriculture, Food Security, and Public Health: Global 

Issues – Global Solutions” 

For global health initiatives to be successful in the long term, 

there needs to be a secure and affordable safe food and water 

system in place. All the medicines in the world can’t cure 

starvation. Agriculture is about producing food, feed, and 

fiber. Many factors will impact agriculture in the future, 

including such things as global climate change, the loss in 

plant, animal, and microbe genetic diversity (biodiversity), 

and the ever-increasing demand for water. On the other hand, 

many scientific breakthroughs in areas such as transgenic 

disease, pest-resistant and stress-resistant plants, transgenic 

and conventional biofortified food crops, and plant-derived 

pharmaceuticals will potentially have huge positive impacts 

on food production and public health. While these have great 

potential to help alleviate much of the global food and public 

health crisis, sadly, many may not be adopted because of the 

political structure in place in countries around the world. 

Governmental policies also may restrict and actually impede 

further research into many critical areas of science. These are 

monumental issues to be sure, but not insurmountable. They 

are global issues and they will require global solutions.

“Welcome and Introduction –When 

Agriculture Fails” 

Agriculture is one of the world’s great success stories. Our 

ability to grow food and fiber to feed, clothe and shelter almost 

PROgRAM HigHligHtS 

The Centennial Meeting features an expanded version of our traditional plenary session. 

7 billion people is nothing short of remarkable. However, 

starvation and malnutrition is still rampant throughout much 

of the world. Global agriculture and, in fact, humanity 

itself, faces many new challenges. The increasing decline in 

the planet’s rich biodiversity is looming large. Global climate 

change will negatively impact agriculture in many ways and 

the conflict between water for agriculture and water for public 

health and sanitation continues to get worse in many areas of 

the world. These are global issues and they will require global 

solutions. If the developed world is intent upon improving 

the public health of hundreds of millions, even billions of 

people, a revitalization of, and support for, agriculture must 

be a vital ‘first step’ in the process. What we do as agricultural 

scientists is paramount and a big piece of the solution. When 

agriculture fails, humanity fails. This special Centennial 

Plenary Session entitled “Agriculture, Food Security, and 

Public Health: Global Issues – Global Solutions” will address 

the issues discussed above.

“Biodiversity and Agriculture” 

Since the origin of crop agriculture and animal domestication 

starting approximately 10,500 years ago, there has been a 

steady erosion of biodiversity throughout the world with 

some 11% of the land surface devoted to crop agriculture 

and another 20% to pasture on natural lands, most of it 

unsustainable. Natural biodiversity has decreased markedly in 

the face of the spread of this intensive land use. Crop diversity, 

in contrast, first expanded and is now decreasing in the face of 

commercial-scale agriculture. Where should we be aiming to 

preserve biodiversity for the future?

“Agriculture in a Changing Environment” 

Agriculture is potentially sensitive to many dimensions of 

climate change, through both direct and indirect drivers. 

Responses to warming and altered precipitation, the best 

understood responses, create some winners and some 

losers, with the fraction of losers expanding with increasing 

warming. Indirect responses, from altered pests, weeds, 

disease, competition for irrigation water, or competition with 

other land uses, are less well understood, but will likely be 

as important, in many settings, as the responses to the direct 

effects. Rapidly increasing demand for biomass energy as an 

offset to fossil fuels adds further complications to the future of 

agriculture for food.

“The Global Water Crisis: Balancing Water for Agriculture 

and Public Health” 

Access to clean drinking water and sanitation is a basic need and 

a human right. Unfortunately, half world’s population does not 

have access to sanitation; more than one in six people still lack 

reliable access to drinking water. This has led to a severe public 

health crisis. The problem is particularly acute in the developing 

world, where more than 70 percent of water withdrawal is used 

for irrigation purposes. In addition irrigated agriculture and the 

dominant model of food production contribute substantially 

to soil and water contamination. In short, the current model of 

irrigated agriculture negatively affects public health in myriads 

of ways. The challenge we have is that of ensuring a synergy 

between drinking water and sanitation needs on the one hand 

and food production systems on the other. This presentation 

will explore both the way in which current food production 

systems worsen the water crisis and the possibility of creating 

food production systems that are sustainable, meet the needs of 

the water poor, help maintain the environmental health, and 

contribute toward improving the public health.

“Revitalizing Support for, and Impact of, Plant and 

Agriculture Sciences” 

After decades of decline, real food prices are rising, spurred 

dramatically upward by a perfect storm of increased demand, 

limitations on supply, and a need to conserve land, water, and 

energy to prevent even greater impacts on the environment. 

The good news is that we have unprecedented scientific and 

economic capacity to improve the efficiency and productivity 

of agriculture - if we reverse the long decline in investment 

in agricultural science, technology, and development, and 

focus more deliberately on useful, beneficial outcomes. The 

Bill & Melinda Gates Foundation has launched a major effort 

to support agricultural development, including agricultural 

science and technology, but the need far surpasses the 

resources of a single foundation. We must achieve a global 

commitment to innovation that is proportionate to the great 

needs and opportunities for improving agriculture. And we 

must ensure that the fruits of those investments reach all the 

world’s farmers in appropriate and effective ways.

“Biopharming and Plant-Derived Pharmaceuticals” 

Although plants have been used for millennia as sources 

of medicinal products, it is only in the last decade that the 

tools of genetic engineering have been applied to plants to 

create a new biomanufacturing system for pharmaceutical 

products. Protein drugs, such as monoclonal antibodies, 

subunit vaccines, and human enzymes are examples of new 

products that can be produced in plants. The status of plant 

biotechnology used for pharmaceutical expression in plants, 

lead products in the pipeline, and relevant regulatory processes 

to ensure safety and efficacy of these products will be reviewed.

“Plant Biotechnology and Agriculture: Is There a Role for 

Public Sector Scientists?” 

Plant virus infections can occur in most crop plants and in 

some cases are controlled by specific or non-specific host 

genes that confer resistance or tolerance. In cases where genes 

for host resistance are not identified, a variety of transgenic 

approaches have been demonstrated to be effective in 

conferring virus resistance. This lecture will explore the role of 

selected transgenic technologies in virus disease resistance and 

the potential to reduce virus diseases and enhance crop yields.

“The Interface of Science and Policy: The Crucial Roles of 

Food and Health in Economic Development” 

Improved health for the entire population, especially those 

in deep poverty and/or disenfranchised subpopulations, is 

an imperative in every country for individuals to learn, to 

contribute to economic growth, and to make decisions that 

help control population numbers. The eight U.N. Millennium 

Development Goals for 2015 are based on credible science and 

feasible technology, broad political agreement with financial 

commitments in 2001, and an overall integrated strategy, 

complemented by health and agricultural initiatives from the 

Bill & Melinda Gates Foundation and others. Nevertheless, at 

this midpoint to 2015, there is a chasm between good science 

and lofty goals, on the one hand, and real progress, especially 

in sub-Saharan Africa, Latin America, the Middle East, and 

North Africa. The main challenges are poor governance, 

extreme poverty, growing inequalities even within prosperous 

countries, and policy neglect, compounded by inadequate 

global investment.

Sponsoring Committees: Collections and Germplasm, 

Mycology 

Collections of plant pathogens have played important roles in 

the advancement of plant pathology and biology in general, 

and our culture collection system has evolved with changing 

research needs. Despite that, the collection system of plant 

pathogens in the nation as a whole is fragmented and lacks 

of good organization. Now our culture collection system is 

at a critical juncture. As stewards of many phytopathogen 

collections are at or near retirement, the future of those culture 

collections is uncertain. This symposium will examine the 

history of our culture collection system, discuss potential 

solutions to the current problems, and explore the prospects of 

having a national plant pathogen collection system.

Moderator: Dennis Halterman, USDA-ARS/University of 

Wisconsin-Madison, Madison, WI 

Sponsoring Committees: Biochemistry, Physiology, and 

Molecular Biology, and Host Resistance 

This symposium will cover the role of post-translational 

modifications in host/pathogen interactions. Protein 

modifications such as phosphorylation, ubiquitination, and 

ADP-ribosylation are now being studied intensively for their 

role in proper signaling during disease resistance responses. 

Recent results discussed in this growing area of research 

will expose attendants to what will be an important future 

scientific focus of molecular plant-microbe interactions.

Epidemiology and Food Security: Historically Linked,

Sponsoring Committees: Epidemiology, Crop Loss 

Assessment and Risk Evaluation 

Epidemiology has been inherently linked with food security. 

As the world’s population continues to grow, agricultural 

researchers will be faced with the important goal of meeting 

the world’s food demand. Epidemiology is one of the areas 

that can help contribute to addressing this issue. In order 

to continue to improve food security, epidemiologists 

need to provide adequate measures of agrosystem (and 

ecosystems) performance, in relation with plant health. Also, 

epidemiologists need to provide accurate, if not precise, 

measurements of the efficiency and costs of management that 

have many dimensions and units. Finally, epidemiologists 

need to be able to generate scenarios for overall management 

and thresholds for actions in complex, nonlinear systems. 

This special session will examine the historical context of food 

security and the role of epidemiology, highlight the current 

state of how epidemiological research contributes to food 

security, and discuss the future needs for epidemiologists to 

continue to contribute to food security.

Sponsoring Committees: Soil Microbiology and Root Diseases 

Many new and rapidly changing technologies are available 

for characterizing microbial communities in soil. Molecular 

biology advances now allow for the detection and 

characterization of a myriad of soil microbes, including those 

considered nonculturable. New statistical approaches permit 

a quantitative examination of soil microbial communities. 

However, optimization of these emerging technologies and a 

comprehensive understanding of their limitations tend to be 

elusive. We propose to organize a symposium highlighting 

effective utilization of emerging molecular and statistical 

methodologies for examining soil microbial communities. 

The speakers will focus on practical challenges, such as 1) 

selecting the most effective and appropriate methodologies to 

examine various types of microbial communities mediating 

or influencing soilborne diseases; 2) selecting appropriate 

experimental designs, sampling methods, and sample sizes; 

and 3) understanding and dealing with limitations of the 

methodologies.

Sponsoring Committees: Forest Pathology 

The establishment and spread of non-native, invasive forest 

pathogens in the US during the 20th century have changed 

forest composition, structure, and function in rural and urban 

landscapes. Because recovery from an invasive pathogen is 

typically an extremely long-term process, it is especially critical 

to incorporate lessons from previous invasions by diverse 

pathogens. Case studies covering historical perspectives on what 

was done to contain, prevent spread, and mitigate each disease 

through the century will be presented. This symposium will 

focus on lessons learned from historical pathogen invasions to 

improve our response to current and future threats.

Late blight of potato occurred in Europe during 1844-46, 

causing heavy crop losses, which resulted in the famous Irish 

famine. In the past 160 years, more than 80 Phytophthora 

species have been described. Today, virtually every crop is 

affected by one or more Phytophthora species. The science 

of plant pathology was borne after describing Phytophthora 

infestans, the causal agent of late blight of potato. This 

symposium will focus on reviewing the historical significance 

of Phytophthora pathogens and will evaluate current and future 

outlook for management of important Phytophthora diseases.

Bacterial Type III Secretion Systems: From Enigmatic avr 

and hrp Genes to Type III Effector-Mediated Suppression 

of Plant Immunity 

3:15 – 6:15 p.m. * 208 CD 


Organizers/Moderators: Jim Alfano, University of Nebraska, 

Lincoln, NE, Mary Beth Mudgett, Stanford University,

Sponsoring Committees: Bacteriology, Biochemistry, 

Physiology, and Molecular Biology; Genetics; and Graduate 

Student. 

Financial Sponsors: Monsanto, Pioneer 

This session will provide history on important discoveries on 

the type III protein secretion system and recent progress on 

bacterial type III effectors and their targets inside plant cells. 

Two talks will provide historical perspectives on avr and hrp 

genes as well as introduce our current state of knowledge. We 

now know that the vast majority of bacterial avr genes encode 

type III effectors and hrp genes encode a type III protein 

secretion system that injects type III effectors into plant cells. 

These perspective talks will highlight how avr genes and hrp 

genes were independently discovered and how it was discovered 

that type III effectors, many of which are encoded by 

avr genes, were injected into plant cells by the Hrp type III 

protein secretion system encoded by hrp genes. The other 

talks will focus on more recent advances in our understanding 

of the activities of specific type III effectors and their plant 

targets/cofactors and how the majority of type III effectors are 

apparently targeting the plant innate immune system. Highlighting 

the important molecular and biochemical advances 

made in the past 20 years, this session will provide insight to 

both the achievements and challenges that lie ahead in the 

study of bacterial pathogenesis and will provide a breadth of 

information fitting of a session held at the Centennial APS 

meeting.

Sponsoring Committees: Mycology 

Well over 50 fungal genomes have been sequenced and 

annotated to date, including those of many plant-pathogenic 

fungi. Because of this plethora of genome sequence 

information across many fungal taxa, we are now in a position 

to not only more fully address and investigate pathogenicity 

mechanisms in fungi using functional approaches but also to 

look at pathogenicity from an evolutionary perspective. We 

are proposing a symposium that highlights the most recent 

developments/advances in the fungal genomics field related 

to advances in dissection of pathogenicity. We plan to invite 

internationally acclaimed speakers in this exiting area of 

molecular plant pathology to discuss the current status of their 

respective projects. One particular area of interest is the use of 

new sequencing platforms and technologies for these projects 

and the advantages and disadvantages associated with each 

approach, including bioinformatics-related issues. Lastly, one 

other area of interest is the use of high-throughput functional 

approaches coupled with genome sequence information for 

identification of pathogenicity determinants in fungi.

Sponsoring Committees: Bacteriology 

This symposium will highlight exciting research about plantpathogenic 

and symbiotic bacteria studied in ecologically 

relevant contexts (i.e., on natural hosts, outdoors, on economic 

crops, etc.). Invited speakers will show how modern tools have 

revealed the biological secrets of diverse bacterial species that 

associate with plants. In keeping with the centennial theme, 

we will open the symposium with a historical presentation 

connecting the biological questions that occupied plant 

bacteriologists in the first decade of the twentieth century with 

those that we focus on today.

Balancing Natural and Augmentative Biocontrol in 

Organic Cropping Systems 

1:00 – 2:30 p.m. * 205 AB 


Organizer/Moderator: Brian McSpadden Gardener, The 

Ohio State University-OARDC, Wooster, OH 

Sponsoring Committees: Biological Control 

A moderated open-forum discussion session (not a 

symposium). Moderator and participants will address 

questions such as: To what extent do organic farmers currently 

depend on cover crops, composts, and green manures 

to enhance natural biocontrol? What fraction of organic 

growers are turning to biopesticidal inoculants? Under 

what circumstances are inoculants and other augmentative 

biocontrol strategies being used? Can we define the conditions 

under which natural biocontrol processes must be augmented

y inoculation to optimize production efficiency and/or 

enhance food quality? And, how does reliance on natural 

and augmentative biocontrols vary by crop, regions, and 

internationally?

Organizers/Moderators: Courtney Gallup, North Carolina 

State University, Raleigh, NC; Katherine Whitten Buxton, 

North Carolina State University, Raleigh, NC 

Sponsoring Committees: Graduate Student, and Teaching 

Universities are investigating novel teaching and learning 

models and new technologies to successfully influence 

students in today’s changing culture. This symposium will 

explore effective teaching tools that heighten student academic 

engagement and attract a broader audience into the discipline. 

Active and problem-based learning techniques maintain 

interest and relevance throughout a course. Furthermore, wellplaced 

technologies and web resources enhance understanding 

in a traditional classroom, reach nontraditional students, 

and provide a means to encompass more material within a 

departmental curriculum. In order to assess their effectiveness, 

teachers must be able to critically evaluate strategies to 

determine the effects on student learning and outcome. This 

symposium offers insight to these topics and explores ideas and 

tools that may enhance a plant pathology classroom.

The Future of Plant Pathology 



Organizer/Moderator: David Schmale, VPI SU, Blacksburg, 

VA 

Sponsoring Committees: Centennial Planning Committee 

The field of plant pathology is pushing forward with new and 

exciting technologies and applications. Powerful genomics 

and bioinformatics tools are enabling researchers to examine 

interactions among entire microbial communities, and new 

high-power computing capabilities are mining and comparing 

genomes and proteomes of plant pathogens and their hosts. 

Online databases are linking living plant pathogen culture 

collections to publicly available morphological and sequence 

data. A new ‘wired’ generation of students needs to be amused 

58 

and entertained in the classroom, and we must find unique 

ways to attract and retain these individuals as agricultural 

professionals.

Aflatoxins, the Toxins that Redefined Plant Disease 

9:00 – 11:30 a.m. * 205 CD 


Organizers: Gary Payne, North Carolina State University, 

Raleigh, NC; Peter Cotty, USDA/ARS, University of Arizona, 

Tucson, AZ 

Moderator: Charles Woloshuk, Purdue University, West 

Lafayette, IN 

Sponsoring Committees: Mycotoxicology 

Although the toxicity of diseased plants to humans has been 

recognized for hundreds of years, aflatoxin contamination 

remains the best-described example of this link. Research 

on this toxin ushered in the modern era of mycotoxicology, 

and aflatoxin remains the best-described mycotoxin. It has 

been 50 years since aflatoxin was shown to be the cause 

of the mysterious Turkey X disease. It is now recognized 

as one of the most potent naturally occurring carcinogens 

known, and it continues to affect human and animal health 

and international trade. The impact of aflatoxins on human 

populations in both Asia and Africa is well documented. This 

symposium will commemorate the near 50 years of research 

on aflatoxin and will highlight its toxicity and importance 

to developing countries, its well-characterized biosynthetic 

pathway, and recent information gleaned from the genome 

sequence and available DNA microarrays. Also covered will be 

a phylogenetic analysis of the aflatoxin-producing species of 

Aspergillus and the successful use of biocontrol techniques to 

control this disease.

Verticillium spp. are globally distributed, broad-host-range 

fungal pathogens causing vascular diseases for which new 

effective disease control measures need to be developed. 

The symposium will start with a historical perspective of 

the importance of this extremely diverse group of plant 

pathogens and the work carried out to date. The symposium 

will continue with discussions of contemporary work on 

the molecular genetics of fungal growth, development and 

pathogenicity as well as host defense mechanisms. Finally, 

the symposium will conclude with a discussion of future 

directions for Verticillium research that includes presentation 

of Verticillium genome sequencing progress and how these 

new findings may collectively lead to better understanding and 

control of these significant plant pathogens.

Plant Virology: Impact on Science and Society 

9:00 – 11:30 a.m. * 208 CD 


Organizer/Moderator: Alexander Karasev, University of 

Idaho, Moscow, ID 

Sponsoring Committees: Virology 

Plant virology had a profound effect on the development of life 

science disciplines in the past 100 years. From virus purification 

to crystallization, to identification of the genetic material, 

to development of methods of detection, to elucidation of 

mechanisms of interaction with the host. It is important to 

understand that virology as an integral part of plant pathology 

made a seminal contribution to the development of modern 

human society. Myron Brakke was a visionary scientist who 

advanced plant virology, and molecular biology as a whole. He 

introduced a concept of gradient fractionation and successfully 

used it to discover divided genomes in plant viruses. He was 

a member of the National Academy. This symposium will be 

devoted to Myron Brakke and focused on impact the plant 

virology had on science and society in the 20th century, and by 

extension on its modern role.
