safety Tips 

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

areas. Remove name badges when outside the hotel 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 it 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. 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 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 it 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, and at the 

Oregon Convention Center, use any house phone and 

dial “0” during an emergency. The operator will alert 

the emergency response team. An Emergency Medical 

Technician (EMT) will be available during meeting hours 

at the Convention Center.

Welcome to Portland 

and to the 2009 APS Annual Meeting! Now is the time to get involved. 

The 2009 APS Annual Meeting highlights APS’s efforts to continue moving 

forward and expand the boundaries of what our science can be. The annual 

meeting serves as your chance to come together, network with your peers, 

discuss critical issues in our science, discover the methods of others, and get 

to know each other. It is your link to the latest research and technological 

developments in our industry and helps you come face to face with the top 

scientists in our field. 

With that in mind, the APS Annual Meeting will become an even more 

effective tool for our science and for you personally if you get involved at 

every level. The APS Annual Meeting can become an indispensable tool for plant pathologists who 

want to build authentic, genuine relationships and get to know the people who matter most in 

our field. In a tough economy, it is more important than ever to ensure that you are doing all you 

can to remain visible in your place of employment or your organization. Attend social gatherings 

and networking events, visit with colleagues from around the world, meet with poster authors and 

speakers, and ask questions in the sessions. 

As the chair of the 2009 Annual Meeting Planning Committee, I could not be more proud of the 

program we’ve put together, including thirty-two special sessions, three field trips, two workshops, 

240 oral technical presentations, and over 650 posters. This year’s program also includes the addition 

of a “hot topic” session specifically chosen by the APS Annual Meeting Planning Committee 

for its timeliness and importance as it relates to plant pathology. This year’s hot topic, The Use of 

Fungicides to Promote Plant Physiological Benefits in Crops, is one of our field’s most pressing issues 

and the session will bring together some of the world’s most renowned speakers on the subject. 

Finally, I would like to thank members of the Scientific Planning Board 

and the APS Annual Meeting Program Planning Committee for their 

dedication and hard work over the past year in helping me plan this year’s 

meeting. I’m looking forward to a great time here Portland!

Government Sectors of Plant Pathology 

1:00 – 3:00 p.m.; D135 

Sponsoring Committee: Early Career Professionals 

Organizer: Lyndon Porter, USDA-ARS, Prosser, WA, U.S.A. 

This workshop focuses on the following: 1) preparing for an 

interview, what you should know and do, 2) how to interview, 

what to do and not to do, 3) application and interview 

experiences from early career professionals who recently obtained 

jobs, and 4) discussion panel of people who frequently 

conduct job interviews from the government, private, and 

academic sectors. This workshop is appropriate for early career 

professionals and graduate students.

A Statistical Workshop on Linear Regression 

1:00 – 5:00 p.m.; E146 

Sponsoring Committee: Epidemiology 

Organizer: Larry Madden, Ohio State University, Wooster, 

OH, U.S.A. 

This workshop teaches the basic methods of linear regression 

analysis. Emphasis is placed on utilization of SAS statistical 

software to fit models to data, diagnose the appropriateness 

of the chosen models, and assess the reasonableness of 

implicit statistical assumptions. Special emphasis is placed on 

utilization of the Output Delivery System of SAS to prepare 

graphs of key results. Participants will learn how to use robust 

regression modeling to deal with data with outliers or when assumptions 

about normality are not reasonable. Other specialized 

methods (and corresponding SAS computer code) will be 

introduced, such as logistic regression for binary data, quantile 

regression for analysis of heterogeneous data, where the tails of 

the distributions have a different relationship with a predictor 

than does the mean of the response variable; and penalized 

splines and other smoothing models, for when there is no 

simple or obvious functional relationship between a response 

variable and a predictor. Participants should bring a laptop 

with SAS (9.1 or later) installed.

Organizers: Caroline Roper, University of Connecticut,

Connecticut, Storrs, CT, U.S.A. 

Moderator: Caroline Roper, University of Connecticut, Storrs, 

CT, U.S.A. 

Sponsoring Committee: Bacteriology 

The concept of bacterial multicellularity or social behavior is at 

the forefront of modern microbiology. Bacteria communicate 

18 

with one another via self-produced small molecules often 

called autoinducers. Perception of these small molecules allows 

bacteria to mount a coordinated response in a population 

density-dependent manner. This phenomenon is known as 

quorum sensing (QS). Recent advances have shown that 

QS can occur in organized microbial communities called 

biofilms. Biofilms are often associated with chronic infections. 

Understanding the molecular mechanisms that mediate 

biofilm formation and the bacterial signaling that goes on 

inside a microbial biofilm is key in developing successful 

disease management strategies for bacterial plant pathogens.

Current Status of Citrus Huanglongbing Research and 

Control

Sponsoring Committee: Bacteriology 

Huanglongbing (HLB or yellow shoot disease) is a highly 

destructive disease of citrus worldwide. This disease has been 

endemic in most of the citrus-growing areas in Asia and Africa. 

HLB was found in Sao Paolo, Brazil, in 2004. In the United 

States, HLB was found in Florida in 2005 and in Louisiana in 

2008. The recent spread of HLB to the Americas is threatening 

the citrus industry in United States and Brazil; both are major 

citrus-growing countries. Extensive efforts have been made to 

study and control HLB in many citrus-producing countries 

in the past 50 years. Two major challenges remain: 1) limited 

information is available about HLB biology, particularly the 

disease etiology; and 2) effective HLB control strategies are not 

available. This session will discuss the geographical, historical, 

biological, and control perspectives of the disease. HLB 

researchers with working experience from different countries 

will share their most recent information and first-hand 

experience in combating the HLB problem.

Sponsoring Committee: Virology 

The life cycle of a plant virus is intimately linked to the normal 

plant genome expression. To survive and successfully evolve, 

viruses acquired a host of counter-measures to evade and 

overcome host plant defenses. Virus replication and underlying 

virus-host interactions in a plant may become visible through 

a range of virus-induced symptoms, and sometimes result in 

plant disease. In recent years, many such virus-induced outcomes 

were studied in great detail. We want to address modern 

developments in the studies of virus-plant interactions on the 

broadest possible scale. These will include mechanisms of plant 

defense systems, host and virus factors shaping the disease 

response, and evolutionary aspects of virus-host interactions.

Primum non Nocere: Risk Assessment for Biological 

Control 

8:30 – 11:00 a.m.; C120-122 


Organizer/Moderator: Brantlee Spakes Richter, North 


Sponsoring Committees: Soil Microbiology & Root Disease; 


Biological control of plant pathogens shows great prospect 

for suppressing plant diseases where chemical controls are 

unavailable, ineffective, or cost-prohibitive. As well, they are 

relied upon by a rapidly growing organic produce industry, a 

lucrative niche market fed by consumers who have concerns 

over the health and environmental impacts of agrochemicals. 

Biocontrol products have the potential to be a sustainable, 

affordable, environmentally responsible tool in integrated 

pest management approaches. However, no control method is 

entirely without its own risks. We have already seen promising 

biocontrol products drop from the path to development due 

to concerns over human pathogenicity among immunocompromised 

individuals, and recent outbreaks of E. coli have 

raised concerns over the use of undefined products, such as 

compost or compost-based microbial amendments. In many 

cases, the same organisms that have demonstrated efficacy 

in combating plant pathogens or inducing plant resistance 

have also been implicated in human maladies, postharvest 

problems, or other plant diseases. In order to foster the 

development of biocontrol products that are both safe and 

effective, we need to ensure that we are including unbiased and 

thorough risk assessment principles throughout the research 

and development process. As the unifying and guiding entity 

for phytopathological research and practice within the Western 

Hemisphere, and perhaps the world, APS has the responsibility 

to foster discussion of the potential risks associated with 

new developments in the field of plant pathology. However 

promising our research may appear, and however optimistic 

we may be about our own work, as scientists, researchers, and 

academics, we must openly face the risks associated with each 

new idea and incorporate risk assessment into the fabric of our 

development process.

The advent of genomics unveiled complete sequences of 

pathogenic phytobacteria, such as Xyllela fastidiosa, Ralstonia 

solanacearum, and Agrobacterium tumefaciens. These whole 

genome sequences demanded extensive labor, time, and money 

investment. Since then, the technology of high throughput

sequencing has permitted scientists to quickly and easily sequence 

phytopathogen genomes from all domains of life. Our 

tool box of new and cost-effective pyrosequencing and microarray 

technologies remains a largely untapped resource for 

the examination of plant pathogens and soilborne microbial 

communities. Furthermore, molecular phytopathologists have 

uncovered the biology that underlies pathogenesis through 

gene expression analysis using these sequencing technologies 

and DNA microarrays. This session highlights the technologies 

and research supporting pyro- and high throughput sequencing, 

DNA microarrays, and gene expression analysis to communicate 

the impact of this knowledge.

APS-ISF Collaboration to Implement a System to 

Standardize Naming of Plant Pathogen Races and Strains 

1:00 – 3:30 p.m.; A106 


Organizer: Phyllis Himmel, Monsanto Vegetable Seeds, 

Woodland, CA, U.S.A. 

Moderator: Lindsey du Toit, Washington State University,

Sponsoring Committees: Seed Pathology; Ad Hoc Committee 

on Culture Collections; APS-ISF Ad Hoc Committee on 

Naming Pathogen Races/Strains 

Inconsistency in protocols used to name plant pathogen races 

and strains can undermine the value of disease resistance 

claims made for specific cultivars, particularly in specialty 

crops such as vegetables. A broader understanding of the 

impact of naming pathogen races and strains on the vegetable 

industry is needed. For example, inconsistencies in naming 

of races, pathotypes, and/or strains of the downy mildew 

pathogens of spinach and lettuce, as well as the Fusarium wilt 

pathogens of tomato, melon, and watermelon, cause continuing 

confusion for growers, the vegetable seed industry and 

academia. There is no internationally recognized authority on 

nomenclature for new races and strains. Readily available sets 

of differential host cultivars and reference cultures of pathogen 

races and strains are needed to help standardize the nomenclatural 

system and provide clarity for claims of disease resistance. 

Members of APS, the American Seed Trade Association, and 

the International Seed Federation are collaborating to implement 

a network of private and public research laboratories 

and seed companies in the United States for the maintenance, 

storage, multiplication, and distribution of reference pathogen 

cultures and seed of differential host cultivars, to facilitate 

standardizing the naming of plant pathogen races and strains. 

The proposed system should complement existing systems in 

Europe (i.e., Naktuinbouw in the Netherlands and Group for 

Control and Testing Varieties and Seeds - GEVES in France) 

and comply with U.S. regulatory requirements. The complexity 

and challenges of implementing this system, demand for 

such a system, and proposed protocols will be discussed in 

the session. Feedback from the APS community is critical to 

development of a system of reference pathogen cultures and 

differential host sets for naming of pathogen races and strains 

with guidelines that are accepted globally by the scientific 

community.

Bacteriology/Virology 

Among many new or expanding diseases of significant 

importance are those vectored by insects. These include 

phytoplasmal, viral, and bacterial diseases. Examples include 

introduction of diseases and/or vectors, such as Plum pox 

virus in the Northeast (vectored by aphids) or the introduction 

of the glassy-winged sharpshooter in California, which 

has increased losses from Pierce’s disease (Xylella fastidiosa). In 

addition, warming environments have often resulted either 

in increased insect survival or introduction to regions where 

previously excluded; Pierce’s disease is once more an example, 

as it is becoming more problematic in higher elevations in 

Georgia, North Carolina, and Virginia, and warmer winter 

temperatures may increase the disease in other regions as well. 

32 

In addition, many new diseases have been observed in the last 

few years, and in some cases, the vector relationship is not well 

understood, though propagation is certainly involved. These 

include examples such as Blackberry yellow vein virus, Blueberry 

red ringspot virus, and bacterial leaf scorch of blueberry. 

There are many classical and some new methods of controlling 

vectored or propagated diseases. Speakers will address new and 

expanding diseases and their management.

9th I. E. Melhus Graduate Student Symposium: Integrating 

Pre- and Postharvest Views of Yield and Quality Loss 

8:30 – 11:30 a.m.; A107-109 


Organizers: John Rupe, University of Arkansas, Fayetteville, 

AR, U.S.A.; David Gent, USDA-ARS, Corvallis, OR, U.S.A.;

College, Edinburgh, United Kingdom; Ahmed Fakhoury, 

Southern Illinois University, Carbondale, IL, U.S.A. 

Sponsoring Committees: APS Crop Loss Assessment 

and Risk Evaluation; Postharvest Plant Pathology and 

Mycotoxicology 

This session features six presentations on graduate thesis work 

highlighting research aimed at providing a better understanding 

of the links between pre- and postharvest losses in yield 

and quality. Postharvest losses resulting from infections initiated 

in the field can be particularly high in perishable produce 

crops, which are key to healthy diets and help reduce public 

health service costs. Globally, the availability of affordable, 

high quality produce to consumers depends on nonrenewable 

resources. Are these supply chains sustainable into the future? 

40 

What can plant pathologists contribute to the development 

of more sustainable alternatives? Mycotoxin contamination 

continues to threaten human and livestock health, increase 

production costs, and reduce production efficiency across the 

globe. How are plant pathologists combining their skills with 

other disciplines to solve these problems? The graudate student 

presenters have been selected on the basis of the significance 

of the contribution to new understanding in the area of plant 

disease management in supply chains.

Sponsoring Committee: Teaching 

Following a 2007 survey of graduate students and post-doctoral 

fellows, the heads of graduate programs, and the employers 

of plant pathologists, APS hosted a national workshop on “The 

future of education in plant pathology and related disciplines.” 

The workshop was held March 19–20, 2009, in Washington, 

DC with major financial support from NSF, USDA-CSREES, 

and USDA-ARS. The workshop brought together a diverse 

group of people to discuss educational issues in the plant sciences. 

This special session provides an overview of the topics 

discussed at the national workshop and action items derived 

from it. Speakers describe perceived educational vulnerabilities 

in plant pathology, what constitute core competencies in plant 

pathologists, how to attract students into the plant sciences, 

and the proper roles of professional societies like APS in the 

education arena. The goal of the session is to determine how 

plant pathology is being affected by the changes taking place 

in educational institutions, and how APS might engage at a 

national level to shape the future.

Host factors associated with disease resistance and the pathogen 

effectors that trigger host defenses have been extensively 

42 

investigated in the last decade. Recently, increasing attention 

has been focused on host and pathogen factors that promote 

compatible interactions and disease development. This session

Pathogens that infect the vascular systems of plants and cause 

wilting, such as some species of Verticillium, Ralstonia, and 

Fusarium, are as diverse as the plants they infect. However, 

difficulty in quantitating disease symptoms, developing rapid 

screening methods for resistance, separating immunity and 

tolerance, and incorporating resistance into breeding lines, 

all present challenges regardless of the pathogen or host being 

studied. By bringing together scientists studying resistance to 

these diseases, we hope to foster discussion of challenges and 

successes that might not normally be presented in a session 

that is specific to the pathogen type.

Cucurbit Downy Mildew: Re-emergence of a Historical

U.S.A. Corporation 

After more than four decades of successful control using 

resistant cultivars, downy mildew (caused by Pseudoperonospora 

cubensis) reemerged as the single most important problem 

facing cucumber production in the eastern United States. 

The problem was first detected in North Carolina in 2004 

and has since expanded its geographic range to include the 

Upper Midwest, parts of Canada, west Texas, and most states 

in between. Yield losses have been catastrophic, in some cases 

forcing growers to abandon fields within one to two weeks after 

disease detection. How did this happen and what has been 

the response from producers, extension, industry, and research? 

Answers to these questions and the lessons learned along the 

way are germane to many pathosystems and to phytopathology 

in the broadest sense. This session will feature the programs 

that have been on the front lines and will highlight the latest 

research and extension efforts on this important pathosystem.

Organizers: Paola Veronese, North Carolina State University,

Sponsoring Committee: Genetics 

Plants acquire resistance to environmental stress by reprogramming 

gene expression and metabolism, gaining a new

equilibrium between growth, development, and survival. 

Important advances have been made in the understanding of 

transcriptional changes induced by environmental constraints 

and in the identification of signaling proteins and transcription 

factors which regulate the stress-induced gene expression. 

Although stress-responsive genes still represent an important 

aspect of stress adaptation, the simple observation of the 

transcriptome provides only a rough and largely incomplete 

picture of plant response to stress. The amount of mRNA 

available for translation can be affected at different steps of 

the process of RNA maturation, ranging from RNA transcription 

to splicing, from transport to translation initiation, 

and degradation by RNAi. Evidence is accumulating about 

reciprocal actions among different kinds of transcriptional, 

post-transcriptional, and post-translational regulations. The 

characterization of this regulatory network is crucial for the 

deeper understanding of the molecular mechanisms governing 

plant adaptation to the environment as well as for the practical 

purpose of improving crop disease resistance.

Meta-analysis has been a fundamental method for data 

analysis in the medical, sociological, behavioral, and ecological 

sciences for many years, but is only now being used in plant 

pathology. This session will address the use of meta-analysis 

as a quantitative approach for evidence synthesis in plant 

pathology. Speakers will address 1) justifications for combining 

results from multiple studies as opposed to relying solely 

on the results from individual studies to make conclusions 

regarding treatment effects and relationships among variables; 

2) different methods for quantifying treatment effects across 

studies, obtaining treatment effect-size information from 

published and unpublished studies, and interpretation of 

the results for different types of chosen effect sizes; 3) use of 

Bayesian and likelihood-based approaches for synthesizing 

evidence from simple and complex studies (consisting of oneto-several 

effect sizes); and 4) case studies on the use of metaanalysis 

in plant protection and epidemiology.

With the advent of genomics, several model systems have been 

characterized extensively. However, genomic resources for 

most agronomically important pathogens are just emerging. 

This session will highlight pathogens whose genomes are in 

various stages of sequencing and assembly. More importantly, 

the speakers will discuss how genomic technologies enabled 

them to better understand the biology of these fastidious 

phytopathogens and the challenges/benefits of working on 

difficult pathosystems with smaller communities.

Tremendous efforts and resources are expended to develop 

decision support systems as IPM tools, although many of these 

systems have not been adopted as tools to inform management 

decisions at the farm level. The intent of this session is to 

present current information from multiple perspectives on 

why decision support systems, and IPM in general, are or are 

not adopted. Speakers will present information on risk from 

sociological, economic, and practical grower perspectives 

within a context of agricultural systems in developed and 

developing countries. Case studies will be presented to 

emphasize strategies that should be considered when designing 

decision support tools to improve their value to and adoption 

by stakeholders.

The Use Of Fungicides to Promote Plant Physiological 

Benefits in Crops 

Wednesday, 8:30 – 11:30 a.m.; A107-109 

Organizer/Moderator: James P. Mueller, Dow AgroSciences, 

Brentwood, CA, U.S.A. 

Sponsoring Committees: Public Policy Board; Office of 

Industry Relations 

Strobilurin fungicides are registered in maize and soybeans for 

yield enhancement in the absence of significant foliar diseases. 

Large-scale commercial testing across multiple locations 

provides evidence of yield benefits. Smaller scale, replicated 

field trials intended to document these effects have been 

inconclusive. Yield responses are attributed to the cumulative 

effect of managing multiple secondary pathogens and to direct 

effects on plant metabolism such as changes in photosynthetic 

efficiency and transpiration rate. Some researchers have 

expressed concern about potential unintended consequences 

such as selection for fungicide resistant pathogens or 

suppression of beneficial fungi. This session will review the 

data and provide a balanced discussion representing both sides 

of the topic.
