Relocation of 2010 APS Annual Meeting

Thank You! In May 2010, Opryland in Nashville, TN, sustained severe flood damage due to unprecedented rain in the area and the overflow of the Cumberland River. As a result, the 2010 APS Annual Meeting was relocated to Charlotte, NC. The American Phytopathological Society thanks everyone who has helped us make this transition. We’re looking forward to a great meeting here in Charlotte.

Welcome to Charlotte

and the 2010 APS Annual Meeting

John Sherwood

As the 2010 Program Chair, I want to take this opportunity to thank everyone for your flexibility and patience as we worked to relocate the meeting from Opryland in Nashville, TN, to Charlotte, NC. In May 2010, the City of Nashville and the Gaylord Opryland Resort & Convention Center, the original site of the 2010 meeting, sustained severe damage due to unprecedented rain and subsequent flooding in the area. As a result, the meeting could no longer be held at Opryland and was quickly relocated to Charlotte, NC. The City of Charlotte has seen tremendous growth in recent years and I encourage you to enjoy the beautiful weather, barbecue, and outdoor spaces while you’re here. If you have an opportunity, please extend a “thank you” to the staff of APS who have made this transition appear seamless.

In addition to enjoying Charlotte, I hope you enjoy the meeting. For those new to the APS annual meeting, I encourage you to participate by asking questions in the sessions, attending socials and networking events, and getting to know your fellow APS members and visitors to the meeting. The 2010 APS Annual Meeting theme, Creating Possibilities, is reflected in 27 Special Sessions, 15 Technical Sessions, and one outstanding Plenary Session that encourages us to look to the future, embrace societal changes, and create new possibilities. The meeting’s scientific sessions and networking opportunities offer unlimited opportunity for the exchange of ideas and discussion that keeps our science relevant and it is only through your involvement that APS stays vital.

The APS annual meeting attendees, speakers, and exhibitors are recognized leaders from 122 organizations, 105 universities, and 33 countries worldwide. The APS Annual Meeting consistently promotes academic excellence in an environment that encourages us to learn from each other. It also provides the best opportunity for representatives from academia, industry, and government to come together and share the work they are doing throughout the year. Thus, the annual meeting provides the opportunity to bring together diverse skill sets and insights to accomplish great things and start new activities.

There are several new features at this year’s meeting, including extended poster viewing hours until 10:00 p.m. on both Sunday and Monday and two new APS leadership educational opportunities. In addition, the Opening General Session & Awards Ceremony will kick off the meeting on Monday at 10:30 a.m. This session offers everyone a chance to get together, recognize individuals that have made significant contributions to plant pathology, and learn about the progress of your APS colleagues on projects underway and initiatives proposed for your society. It is also time to recognize members who have passed, and with great sadness, but also great pride, we will honor the late Nobel Laureate and revolutionary plant pathologist Norman Borlaug at the Opening General Session.

Finally, thanks to the members of the Scientific Planning Board, the APS Annual Meeting Program Planning Committee, and APS Staff for their contributions and hard work over the past year. I hope you have a great time here in Charlotte making new friends, seeing old colleagues, and being involved in APS. Enjoy!

John Sherwood APS 2010 Program Chair and President-Elect

Safety Tips Do not travel alone – stay in groups and travel in well-lit areas.

Remove name badges when outside the hotel or 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 a 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 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, phone the local emergency response team by dialing 0. At the Charlotte 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.

The hospital facility located closest to the meeting facilities is: Carolinas Medical Center 1000 Blythe Blvd.

SATURDAY HIGHLIGHTS FIELD TRIP

SATURDAY

Ornamental & Forestry Nursery 8:00 a.m. – 6:00 p.m.

Sponsoring Committees: Diseases of Ornamental Plants; Forest Pathology Organizers: Cristi Palmer, IR-4 Project, Rutgers University, Princeton, NJ, U.S.A.; Margaret Mmbaga, Tennessee State University, McMinnville, TN, U.S.A. Greenhouse and nursery growers will showcase their operations and talk about their disease management programs and how they are integrating cultural, biological, and chemical controls.

Visit long-standing operations and up-and-coming growers to hear how they’ve grown quality plant materials under foliar and root disease pressure during this difficult economic time.

Preregistration required.

WORKSHOPS Scientific Writing for APS Journals 1:00 – 3:00 p.m.; 212AB Sponsoring Committees: Publications Board; Editorial Boards Organizers: Niklaus Grunwald, USDA ARS, Corvallis, OR, U.S.A.; Anthony Keinath, Clemson University, Charleston, SC, U.S.A. This workshop on publishing in APS journals will cover important aspects of preparing and submitting manuscripts to Plant Disease, Phytopathology, and MPMI. The workshop will provide an overview of the review and publication processes and provide guidelines for successful publishing. Participants will gain an understanding of the roles of editors-in-chief, senior editors, associate editors, and anonymous peer reviewers. Emphasis will be put on practical tips for scientific writing that will facilitate publication in APS journals. Topics such as proper formatting, authorship, plagiarism, reviewing, and appropriate subject matter for each journal will be addressed.

The organizers and speakers are editors-in-chief with extensive experience in reviewing and publishing in APS journals. This workshop is geared toward graduate students and early career scientists. Preregistration required.

Meet the Geek: Creating Podcasts and Using Syndicated Content 1:00 – 4:00 p.m.; 216AB Sponsoring Committee: Extension Organizer: Joseph LaForest, University of Georgia, Tifton, GA, U.S.A. This hands-on workshop will help attendees develop skills for specific internet tools used in the dissemination of information. The focus will be on creating podcasts and using syndicated content. Participants will learn to make a short (30 seconds – 1 minute) podcast using syndication services to deliver it to a variety of audiences. The session will support both Mac and PC users. Individuals are encouraged to bring laptops. Preregistration required.

Mixed Models for Data Analysis in Plant Pathology 1:00 – 5:30 p.m.; 211AB Sponsoring Committees: Epidemiology; Crop Loss Assessment and Risk Evaluation (CARE) Organizer: Larry Madden, Ohio State University, OARDC/ OSU, Wooster, OH, U.S.A. It is now common to use linear mixed models (LMMs) instead of traditional ANOVA to analyze data from designed experiments. LMMs formally handle experiments with both fixed (e.g., fungicide treatment) and random (e.g., block, location) effects and properly estimate test statistics and standard errors for all the effects of interest under a wide range of circumstances. Registrants will learn to use the MIXED and new GLIMMIX procedures of SAS to analyze data from common experimental designs in plant pathology. Material covered for the first time will include introductions on generalized linear mixed models (GLMMs), for analyzing discrete data; new graphical methods for assessing model fits; and multiple comparisons of means in the context of mixed models.

This workshop will follow the tradition of the Epidemiology Committee’s workshops on “bringing statistical analysis to the masses.” All registrants must bring a laptop computer with version 9.2 of SAS installed. Preregistration required.

LEADERSHIP TRAINING OPPORTUNITIES APS Leadership Institute Early Career Professionals and Regular Members 8:00 a.m. – 4:30 p.m.; 201AB Sponsoring Committee: APS Leadership Institute Ad-Hoc Committee Organizers: Rick Bostock, University of California, Davis, CA, U.S.A.; Chris Smart, Cornell University, Geneva, NY, U.S.A. This first-of-its-kind APS Leadership Institute is designed to help individuals discover their unique leadership skills and begin to apply those skills to their professional, personal, and societal lives. This highly engaging workshop, facilitated by Teri Balser, University of Wisconsin-Madison, will cover the following areas—what and who are leaders, why leadership is critical to your career and profession, types of leaders, leadership and personalities, developing effective leaders, leaders and change, and leaders in professional organizations. Development of future leaders is critical to the success of any organization and is essential for the long term viability of volunteer-led nonprofit societies. While there is no expected service commitment following this program, a long-term goal is to develop future leaders within APS for those who are interested in such a role. The workshop is intended for a broad spectrum of participants including early, mid-, and senior career professionals as well as the volunteer leadership of APS. Preregistration required. Lunch included.

Teamwork is critical to the success of organizations and companies, but as a young scientist you might not be aware of all of the dynamics at play in a team environment. This unique professional development opportunity will allow you to increase your self understanding and enhance your team performance. You’ll take the Myers-Briggs Type Indicator (MBTI) online prior to the training. Then during this highly interactive session, an expert in talent development from Monsanto will provide you with your results and explain your personality type and those of your colleagues. Team-building exercises throughout the session will focus on team communication, culture, leadership, change, problem solving/ conflict resolution, and stress. You’ll leave the training with a fresh perspective as well as the tools to positively impact your team experiences. The workshop is open to a mix of graduate students and post-docs and is offered through the generous sponsorship provided by Monsanto. Preregistration is required.

This important orientation session is a must-attend event for updates on current APS initiatives and committee procedures.

APS Immediate Past President Jim Moyer, Senior Councilorat-Large Mike Boehm, and Intermediate Councilor-at-Large Carolee Bull will lead discussions highlighting recent APS initiatives, processes for taking action on committee issues, and procedural logistics for chairs and vice chairs. Packets with committee rosters and the Committee Annual Report Form will be provided for each chair. APS committee chairs not able to attend should have a replacement participate.

As obligate parasites, viruses have evolved mechanisms to infect plants and undergo mutations and recombinations to adapt to new circumstances. A wide range of techniques and technologies have been used for developing an understanding of mechanisms of evolution in viruses with different genome organizations and replication strategies. A review of the current knowledge on processes associated with virus evolution and the influence of host plant, cropping methods, etc. on virus diversity and evolution is essential for sustainable crop improvement.

Plenary Session—Looking to the Future:

Possibilities and Challenges in Plant Pathology 1:00 – 3:30 p.m.; Westin–Grand Ballroom The Plenary Session focuses on the 2010 Annual Meeting theme, Creating Possibilities, by featuring speakers focused on issues facing agriculture and feeding the growing population. Speakers from outside plant pathology and agriculture will help us examine the issues of social media and their impact on our science, as well as the importance of global linkages. This session will focus primarily on the future of plant pathology and help us form ideas and realize possibilities for the future.

Presentations The ever-increasing importance of plant pathology Andre Drenth, The University of Queensland, Brisbane, Australia Drenth’s presentation will address the following three questions: 1) How have plant patholgists fed the world and what have the contributions and impacts of plant science been? 2) What are the key challenges with regard to plant production which will enable agriculture to feed a growing world population in the future? 3) What role can plant pathology play in feeding the world? Drenth obtained an M.Sc. degree in plant breeding and a Ph.D. degree in plant pathology on late blight in potato jointly from Wageningen Agricultural University and Cornell University before moving to Brisbane, Australia. In 2006, he established the Tree Pathology Centre, which is focused on the control of diseases in tree crops. Drenth has managed many research projects in Australia and Southeast Asia and has published many papers, book chapters, and a book and is a well-cited author in a range of different areas of plant pathology.

Unveiling the web and making the implicit explicit: How new technologies will do your networking for you and what you can do to take advantage Ian Mulvany, Mendley.com, London, United Kingdom Mulvany will examine some of the trends that are happening now in scientific journals, the internet, and related technologies. He will also discuss some of the potential benefits and potential pitfalls that could face us in this brave new world. Ian Mulvany is head of new product development for Mendeley.com, where he tries to build the tomorrow’s software for today’s researchers. Prior to this he managed Connotea and Nature Network; Nature Publishing Group’s key web applications. He spends much of his time examining the implications of emerging web technologies for the practice and communication of science, and is motivated by the idea that the “filter failure” problem can be overcome with the right tools.

Science and Diplomacy: Global Connections Kerri-Ann Jones, Assistant Secretary of State for Oceans and International Environmental and Scientific Affairs, Department of State, Washington, DC Jones will speak on the topic of importance of international networks for scientific communities and roles our professional society can play. Jones served previously as the director of the National Science Foundation’s Office of International Science and Engineering. Jones has also served as acting director and associate director for National Security and International Affairs in the White House Office of Science and Technology (OSTP).

Connections are critical for the growth of your career. This social provides the unique opportunity for early career professionals to meet other plant pathologists at a similar career stage. The APS Early Career Professionals Committee will kick off the social, providing an opportunity to learn about the committee initiatives and suggest ideas for future consideration.

New Opportunity! For the first time, academic, government, and industry employers are also invited to join the social to network one-on-one with prospective employees. This relaxed setting will provide the perfect opportunity for recent graduates, post-docs, and those just starting in their career to mingle and hear firsthand from employers what skills and knowledge they are looking for in their current job openings. Refreshments and appetizers are included. This unique, first-of-itskind event is one you won’t want to miss. Preregistration is required.

Graduate Student Social 6:30 – 8:30 p.m.; 213A Sponsoring Committee: Graduate Student Organizer: Heather A. Olson, North Carolina State University, Raleigh, NC, U.S.A. Graduate students—make plans to meet with your plant pathology colleagues in an informal and relaxed environment.

The APS Office of Public Relations and Outreach will also be announcing the 2010 Video Contest winner during the social.

Light snacks and beverages will be served. This event is limited to students only. Preregistration is required.

Broad-Spectrum Resistance: Molecular Mechanisms Involved in Pathogen Reception and Resistance Signaling 8:30 – 11:15 a.m.; 217D Section: Molecular/Cellular/Plant-Microbe Interactions Organizers: Dennis Halterman, USDA ARS, Madison, WI, U.S.A.; Roger Wise, USDA ARS, Ames, IA, U.S.A. Moderator: Dennis Halterman, USDA ARS, Madison, WI, U.S.A. Sponsoring Committees: Molecular and Cellular Phytopathology; Host Resistance Relatively recent advances have been made in determining the molecular basis of broad-spectrum disease resistance in plants. Multiple levels of host responses to pathogen-derived molecules provide distinct sources and mechanisms of broadspectrum resistance. Pathogen recognition receptors perceive conserved microbial molecular patterns to elicit basal defense responses, while resistance genes recognize the presence of pathogen effectors that may be essential for virulence. In this session, we will explore the molecular interface between hosts and pathogens and specifically focus on traits that result in host resistance to a broad spectrum of pathogen strains or types.

Moderator: Fulya Baysal Gurel, The Ohio State University, OARDC, Woooster, OH, U.S.A. Sponsoring Committees: Biological Control; Soil Microbiology Much early work went into the discovery of key mechanisms of biocontrol by bacteria, particularly antibiotics. However, it has become increasingly clear that multiple chemical signals produced by bacteria impact plant health. Also, genomic and ecological studies have shown that some of the most effective individual strains express multiple traits that lead to a robust plant-health-promoting phenotype. This session will cover recent research on the diverse mechanisms by which biocontrol bacteria are now known to promote crop health and suppress plant diseases. After discussing the individual mechanisms under study, the panel of speakers will convene to discuss how and why such mechanisms might be coordinated or integrated in natural systems.

The past few months have seen extraordinary constraints and pressures on global food markets, with dramatic regional and local consequences on food security and societal stability.

Although the situation has eased some, the primary causes for such instability remain unresolved. This special session will focus on research that is underway or should be undertaken to address food security in major human food staples, such as rice, wheat, maize, potato, sorghum, and cassava. Presentations will be given that provide timely information on (i) the importance of plant diseases on global crop productivity; (ii) approaches to prioritizing research efforts; (iii) assessments of constraints and opportunities for new technologies; and (iv) research progress that is contributing to greater food security. Global change due to climate, credit availability, and diminishing natural resources will be presented in context of their measured or predicted impact on food security. Speakers will include experts from world agricultural organizations in the eastern and western hemispheres, and a specialized FAO economist also will be sought.

Refining Systematics (Taxonomy, Nomenclature, Phylogenetics) for Better Resolution in the Population Biology and Evolution of the Oomycetes 8:30 – 11:15 a.m.; 207CD Section: Biology of Pathogens Organizers: Z. Gloria Abad, USDA-APHIS-PPQ-PHPRIPPS-Molecular Diagnostics Laboratory, Beltsville, MD, U.S.A.; Kelly Ivors, North Carolina State University, Mills River, NC, U.S.A. Moderator: Kelly Ivors, North Carolina State University, Mills River, NC, U.S.A. Sponsoring Committees: Mycology; Forest Pathology Financial Sponsor: Widely Prevalent Plant Pathogenic Fungi List Project Although Phytophthora, Pythium, and the downy mildews are among the most studied organisms in systematics, there is still a great deal of confusion in recognizing valid species and new genera. Poorly annotated sequences exist in GenBank, making it impossible to identify some of the clusters for extypes or neotypes and consequently, the proper identity of an isolate. Examples of these complexes include Phytophthora capsici, Phytophthora citricola, Phytophthora drechsleri, Phytophthora megasperma, Pythium irregulare, prov. genus name Phytopythium vexans, and Pythium helicoides. Although morphological and molecular characterization is used for describing new species, some have recently been found invalid.

Establishing proper nomenclature provides a solid foundation for research tied to the species and for associated regulatory and disease control decisions. Experts in systematics, evolution, and population genetics will participate in this session, hopefully stimulating collaboration for addressing these major challenges in oomycete systematics.

Sponsoring Committees: Postharvest Pathology; Pathogen Resistance Financial Sponsors: PACE Intl.; Janssen PMP; Syngenta Crop Protection Several new pre- and postharvest fungicides have recently entered the market. This session will focus on the key drivers for the development of fungicide resistance in the pre- and postharvest crop production systems and establish the views on pre- and postharvest integrated approaches to the sustainable management of fungicide resistance in postharvest pathogens as seen by the fungicide-resistance research community and the companies that are developing these new products. A dynamic panel of speakers has been identified to address this exciting topic. The collaborative output from this session is anticipated to help establish a standard foundation for resistance management recommendations for newly introduced pre- and

postharvest fungicides that are used for postharvest disease control.

Sponsoring Committees: Epidemiology; Crop Loss Assessment and Risk Evaluation (CARE) Have you been avoiding attending one of the statistical workshops over the years because you felt that the topic was over your head? Do you feel you need to shake off that rust when it comes to statistics? If so, this is the statistical workshop for you! R (www.r-project.org) is a programming package for statistical computing and graphics and has become extremely popular, especially since it is free. In this workshop, we will introduce R and illustrate some of the tools that are available for using R, including graphical and statistical. The focus of this workshop will be at an INTRODUCTORY LEVEL and should be understandable to all who are interested in learning more about statistics and statistical computing. This session will follow the tradition of the Epidemiology Committee’s workshops on bringing statistical analysis to the masses.

All registrants will need to have a laptop with R installed.

Preregistration is required.

Sponsoring Committee: Public Policy Board This session will cover the outcomes of a workshop in the Washington, DC area in February concerning genomic data management and utilization. The speed in which microbial genome sequences are becoming available has created a need for better and more integrated databases and bioinformatic support for microbial researchers. The topic of the session will be the feasibility and mechanics of creating an integrated network of databases, analysis tools, and training in sequence analysis and utilization. Several genomics researchers with extensive experience in database issues, including Brett Tyler, Christina Cuomo, Ralph Dean, and Yong-Hwan Lee will present their views on integrated databases. This will be followed by a general discussion to gain input from APS

members into what types of information and analysis tools the databases should have and how they should be integrated.

Necrotrophic plant pathogens have long been thought to be less sophisticated than the well-studied biotrophs in their interactions with their corresponding hosts. Recent exciting research in the area of necrotrophic plant pathogen interactions has shown that the necrotrophic pathogen interactions may be just as sophisticated in their attack on their respective hosts. Speakers in this session will present research in the area of necrotrophic plant pathogen interactions from both the host and pathogen perspectives. This session will look specifically at virulence/pathogenicity of necrotrophic plant pathogens as well as at the host response to effectors involved in this interaction.
