Moderator: Caroline Roper, University of Connecticut, Storrs, CT, U.S.A.
Sponsoring Committee: Bacteriology

The concept of bacterial multi-cellularity or social behavior is at the forefront of modern microbiology. Bacteria communicate 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.

Diseases of Plants

APS – ISF Collaboration to Implement a System to Standardize Naming of Plant Pathogen Races and Strains

Monday, August 3, 1:00 – 3:30 p.m.; A106

Section: Diseases of Plants
Organizer: Phyllis Himmel, Monsanto Vegetable Seeds, Woodland, CA, U.S.A.
Moderator: Lindsey du Toit, Washington State University, Mount Vernon, WA, U.S.A.
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 US 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 US regulatory requirements. The complexity and challenges of implementing this system, demand for such a system, and proposed protocols will be discussed in the symposium. 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.

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 U.S., 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 U.S. 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 symposium 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 Committees: APS Crop Loss Assessment and Risk Evaluation; Postharvest Plant Pathology and Mycotoxicology

This session will feature 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 non-renewable resources. Are these supply chains sustainable into the future? What can plant pathologists contribute to developing 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.

Molecullar/Cellular Plant Microbe Interactions

Application of Advanced Sequencing and Gene Expression Technologies for Characterization of Phytopathogens

Monday, August 3, 1:00 – 4:00 p.m.; B113-114

Section: Molecular/Cellular/Plant-Microbe Interactions
Organizers: Jonathan Jacobs, University of Wisconsin-Madison, Madison, WI, U.S.A.; Daniel Kluepfel, USDA-ARS, Davis, CA, U.S.A.
Sponsoring Committees: Bacteriology Committee; Biotechnology

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 symposium highlights the technologies and research supporting pyro- and high throughput sequencing, DNA microarrays, and gene expression analysis to communicate the impact of this knowledge.

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.

Mechanisms of Post-Transcriptional Control of Gene Functions in Plant-Microbe Interactions (AS, PTGS, sumoylation and more…)

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.

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.

Challenges for Managing Insect Vectored Diseases

 Among many new or expanding diseases of significant importance are those vectored by insects. These include phytoplasma, virus, 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. 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.

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.

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 symposium 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.

Primum non Nocere:  Risk Assessment for Biological Control

Monday, August 3, 8:30 – 11:00 a.m.; C120-122

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 immuno-compromised 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.

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.
