You have children and/or are a caregiver of an adult family member (moderated by Timothy Murray); 3. You or one of your family members are dealing with temporary or ongoing health or medical issues, including special needs (moderated by Amy Charkowski); 4. You know your rights under the Family and Medical Leave Act, including leave for maternity/paternity, adoption, and care-giving (moderated by Carla Garzon and Samantha Thomas).
Regulation in agricultural research and practice is commonplace. However, despite significant advances in biotechnology, the regulations governing genetically engineered plants and plant pests/pathogens have not changed over the past 29 years. Likewise, regulations concerning select agents have not changed since their inception in 2002. Rules governing both of these groups of organisms are being reevaluated and revisions will appear in 2016. This session will address issues and potential changes surrounding these groups of organisms, as well as examining the regulatory environment for crop protection products.

The genomes of many plant viruses have a coding capacity of fewer than ten proteins, and the primary function of viral proteins have been characterized for many years. However the simplicity of the plant virus genome structure belies the true impact that plant viruses have on the physiology of the plant. This special session is focused on the unique contributions that viruses make to our understanding of the plant phytobiome. Speakers will discuss the ubiquity of viruses in nature as well as the mechanisms utilized by viruses to shape the physiology of their hosts. Viruses have a direct impact on their hosts, but also affect all the biota impacting plant health; thus the virome is an important part of the phytobiome.

Dispersal of plant pathogens is key to development of disease epidemics. Previously, considerable efforts were aimed at understanding physical aspects of dispersal of plant pathogenic spores. Theoretical information on spore dispersal was applied to specific host systems primarily to facilitate prediction of transport over short and long distances. Efforts have also been made to provide field data to support findings from theoretical predictions with respect to velocity of spread over distance. Recently, new attention has been paid to physical and biological mechanisms of dispersal at scales ranging from the microscopic to the continental, and how such information can be applied to understand development of epidemics and manage diseases thereof. This symposium will highlight the current status of dispersal theory and its application to facilitate management of plant disease epidemics.

Just as doctors must have good bedside manner when dealing with patients, plant pathologists must be mindful of their “fieldside manner” when dealing with diverse stakeholder groups, ranging from growers to politicians. Plant pathologists have many opportunities to foster relationships and understanding with these individuals. These relationships are necessary to take our science to practice. The following speakers will share their experiences and advice on effectively communicating and interacting with stakeholders in academic, industry, government, extension, and international settings.

Sponsoring Committees/Sponsors: Microbial Forensics Interest Group, Emerging Diseases and Pathogens Committee
The new discipline of plant pathogen forensics emerged following the 2001 anthrax letter attacks, when the Federal Bureau of Investigation realized that technology advances in microbial forensics were needed to protect both citizens and critical infrastructures, including agriculture. Advancements in PCR sensitivity and specificity made that technology the method of choice for microbial detection in forensic investigations over the next several years. However, recent developments in whole genome sequencing and associated data analysis offer significant advantages for forensic applications. This session will explore relevant technologies and applications of WGS and bioinformatics to microbial forensics in general, and to plant pathogen forensics in particular, including real-life plant disease examples. The Microbial Forensics Interest Group has not held a meeting symposium in approximately 4 years, so this session is timely and important to the future of the blended discipline of plant pathogen forensics.

Dissection of the mechanisms underlying genetic and molecular bases of host resistance is essential for sustainable management of plant diseases. In a research era where genotypic information and molecular tools are widely available and more affordable than ever before, improving the quality and quantity of phenotypic data is essential if we are to exploit the flood of genotypic data that is becoming available and utilize that data in order to understand the molecular basis of host resistance. Plant pathogens adapt quickly to host resistance by means of diverse genetic mechanisms. Partial resistance characterized by quantitative traits of small effect is increasingly important assets for disease management. Accurate phenotyping that reflects plant behavior and sensitive enough to detect these traits under biotic stress is essential if we are to associate resistance phenotypes with an underlying genotype. Discovery of these traits requires innovative, reliable, high throughput laboratory, greenhouse and field disease evaluation methods. We propose to organize a symposium focusing on recent developments in phenotyping methods that can provide reproducible and accurate phenotypic data in field, greenhouse and laboratory settings.

Plant disease may be influenced by phytobiome members beyond the host and the pathogen. Host defenses may be modulated by microbes and insects, the hosts themselves may actively recruit beneficial organisms, and pathogens may be controlled by other microbes or microbial consortia. This session will focus on recent discoveries of the influence of plant-associated insects and microbes on plant disease outcomes, and on how this knowledge may be translated into applications for disease management.

Rose rosette disease (RRD) was first described in the 1940s and has since spread from its source in the Rockies, through the Mid-West to the East coast. It now threatens to decimate the US rose industry. Garden roses, which form the cornerstone of the multi-billion dollar landscape industry, annually generate wholesale US domestic bare root and container production valued at ~ $400 million. RRD is caused by a novel plant virus, Rose rosette virus (RRV), which is transmitted by wind-blown eriophyid mites (Phyllocoptes fructiphilus). Unlike other rose diseases, RRV can kill a rose within two to three years of infection. The current state of knowledge regarding the virus and methods for its detection, the vector, the host and breeding for resistance, and the range of approaches to learn more about this disease and to determine how best to manage it will be presented.

The availability of plant and microbial genome sequences and the advent of RNA-sequencing (RNA-Seq) have enabled in-depth analyses of the changes in gene expression that occur in plant pathogens and their respective hosts. RNA-Seq has provided valuable evidence of the involvement of novel genes in host-pathogen interactions and fresh insight into host defense resposes and suppression. This session explores the application of RNA-Seq to uncover previously “unseen” gene expression patterns in diverse pathosystems.

A combination of increasing threats from emerging diseases and long breeding cycles complicate selection of disease tolerant germplasm. Future woody plant crops will require novel approaches to develop host resistance. Recent advances in several key areas (clonal selection, marker assisted modeling, RNA silencing etc.) can facilitate the process and significantly reduce the cost and time needed for development of woody plant host resistance. This session aims to highlight the latest developments and demonstrate the power of these new tools for those working with woody plants.
