Divisional Forum Meets with Northeastern Communicate Your Science—2012 APS Division to Discuss Engagement Jim E. Adaskaveg, Divisional Forum Chair, email@example.com The APS Divisional Forum met in conjunction with the Northeastern Division’s annual meeting in New Brunswick, NJ, October 12–14, 2011. Council-approved divisional engagement plans were discussed as goals that the divisions will address in the coming years. With the final divisional (i.e., Pacific Division) ratification of APS governance changes for their constitution at the 2011 Joint Meeting in Hawaii, divisions are now being asked to establish ad hoc committees. The committees will focus on one or more of the engagement plans developed by the Divisional Forum last spring. The engagement plans are for the divisions to target programs in education and extension by 1) increasing their exposure to high school students and teachers; 2) attracting promising undergraduate students to the field of plant pathology; and 3) increasing Jim E. Adaskaveg their awareness to private and public sectors of extension. For example, the North Central Division has already approved a half-day Plant Pathology in Focus session for high school students and undergraduates at their next divisional meeting at The Ohio State University in June 2012 to increase awareness of careers in plant pathology. Another goal of the Divisional Forum was to participate in the annual extension round table discussions of the Northeastern Division. Major disease outbreaks over the last year were discussed for each state in the division. Not all of the divisions have such a program and thus the Divisional Forum participated to encourage other divisions to develop extension and outreach awareness amongst membership and possibly public sectors.
Annual Meeting Call for Papers
What do you have to communicate with the plant pathology community? It’s not too early to start thinking about the 2012 APS Annual Meeting, to take place August 4–8, 2012, in Providence, RI, and how you can be a part of it. You are invited to share your latest breakthroughs and research findings with APS at the annual meeting. This is the premier meeting for plant pathology, featuring high-quality plant disease science. The latest topics and issues in plant pathology will be discussed through posters, special sessions, and technical sessions. By presenting a poster or oral presentation, you have the opportunity to share your research with the top minds in the plant pathology community and receive feedback on your work.
During these meetings it was realized by the forum that not all divisions have early career awards for achievements of young professionals in plant pathology. Thus, Divisional Forum representatives were encouraged to develop these ideas with their divisional officers to ultimately recognize and publicize achievements and awareness of outstanding contributions in plant pathology at the regional level. APS Divisional Forum members (left-right) Wade Elmer, Dan An annual APS Graduate Student Roberts, Jim Adaskaveg, David Schmale, Lawrence Datnoff, and Symposium proposal is also being staff member Marci Smith. Not pictured is George Sundin. Other developed by the Divisional Forum. forum members unable to attend include Tim Brenneman and This proposal is to have the winners of Tamra Jackson. the divisional student paper competitions participate in a symposium at the APS Annual Meeting. Monetary travel awards will be established through the divisions. The objective is to showcase award-winning graduate students at the national level and to assist them in launching their careers. n
Be a part of the scientific program by submitting your research. Online submissions for both oral and poster presentations will be accepted February 1 through March 15, 2012.

Editor’s Corner Is There a Tricorder in Your Future? Doug Jardine, Kansas State University, PhytoNewsEditor@scisoc.org For anyone who was or is a Star Trek fan, you would know that a tricorder was a fictional, multifunction device used for sensor scanning, data analysis, and recording data. Mr. Spock wouldn’t think of exploring a planetary surface without one, and Dr. McCoy was able to make on-the-spot, detailed medical diagnoses by waving his handheld version over the patient. After attending the recent Third National Meeting of the National Plant Diagnostic Network (NPDN), I am not so sure that a crude, but functional, tricorder-like device for plant pathology diagnosticians is not all that far off in the future.

The theme of the conference was “Next Gen NPDN.” The opening symposium was “New Technologies in Diagnostics.” Topics included loop-mediated isothermal amplification, next-generation sequencing for identification of plant pathogens, DNA chip arrays for virus identification, and the potential of microfluidic systems for diagnostics in plant pathology. Can you imagine doing PCR in a device about the size of your smart phone? Testing for multiple pathogens in a plant sample at a cost of a few pennies a run? The possibilities are closer than you think! Doug Jardine
One of the most interesting presentations at the conference was by Arturo Casadevall, Einstein College of Medicine, who presented a paper entitled “Emerging fungal pathogens—Past, present, and future.” One of his discussion points was why is it, when there are approximately 1.5 million species of fungi, only about 150 are pathogenic to humans? Hint: It has to do with our body temperature and why we have to eat so much compared to reptiles for instance, that may only eat once a week. If you weren’t one of the nearly 200 plant pathologists in attendance, you are in luck as many of the presentations were videotaped and will be made available on the NPDN website at www.NPDN. org. To sum up the conference, I turn to one of Mr. Spock’s most frequently repeated quotes, “Fascinating!” n

2010 Art in Phytopathology Submission: Mike’s Nose Robin Choudhury, University of California-Davis I took this photo in Blacksburg, VA, where an annual Halloween carving party occurs each year. The owner of the property, Mike, has several acres of land, and this locust tree was near the entrance. He had jokingly added the eyes and mouth to the conch, making it look like a face. I was an undergraduate at University of Maryland at the time, and my former plant pathology teacher (Yilmaz Balci) identified the fungus as Phellinus robiniae. n
Impressive, Dedicated APS Community Continues to Grow
Volunteers are at the heart of APS’s success; we simply could not produce the exceptional experiences, vibrant community, and essential tools that we all value without the contributions of members’ time, talent, and expertise.

Food Safety Starts with Healthy Plants!
2012 Human Pathogens on Plants Workshop
The mission of the Collections and Germplasm Committee is to promote and foster the collection, preservation, improvement, and utilization of U.S. and international resources of microbial and higher-plant germplasm; identify issues relevant to germplasm resources; advocate judicious improvements in collection and germplasm systems; and constructively influence policies and procedures through APS Council by such means as committee proposals, APS publications and discussion sessions, and communications with other scientific societies, governmental agencies, institutions, and industry. Collections of plant pathogens have played important roles in the advancement of plant pathology and related fields. They provide critical links between past and present disease epidemics, facilitate identification of emerging diseases, and are useful in developing control strategies for plant diseases. However, the collection of plant pathogens in the nation lacks a coordinated national system to protect, preserve, and enhance these valuable resources. Currently, the key issue our committee is focusing on is support for the establishment of a national plant microbial germplasm system (NPMGS) to protect endangered collections and teach good collection practices.

Public Policy Update PPB Attends Plant Science Research Summit Jan Leach, PPB Chair, firstname.lastname@example.org What research in plant science is needed in the next 10 years to improve global food supplies using sustainable approaches and increase our understanding of plant biology? To develop a united plan to address this question, a Plant Science Research Summit (Chevy Chase, MD; September 22–23, 2011), organized by the American Society of Plant Biologists (ASPB), brought together 75 plant scientists as well as representatives of federal agencies, professional societies, grower organizations, and other stakeholders of plant science. APS was represented at the summit by Jan Leach, Public Policy Board (PPB) chair; Kellye Eversole (Eversole Associates); and Angela Records (Eversole Associates), public policy fellow. While the summit participants readily agreed that plant science is critical to solving the global food needs, the discussions of “how” and “what is needed” were broad. One key, as summarized in the Science Insider (http://news.sciencemag.org/scienceinsider/2011/09/decadal-plan-for-plant-science. html), is that “Progress will require new model systems, intensively studied species that provide insights useful both in basic and applied research.” The importance of including crop species as models and the tools and information needed to accelerate characterization of the fundamental biological processes important to agriculture were discussed. The need to understand plant genetic diversity and plant-microbe interactions (beneficial and pathogenic) for improvement of economically useful plants was also discussed. Not surprisingly, no common path for plant science emerged from this two-day summit. However, Organizer Gary Stacey (ASPB) indicated that this summit was just the beginning. Over the next several months, a committee will work to capture the ideas from the summit and combine them with input submitted from the broad community to prepare a report that will provide a unified path for plant science and emphasize the critical role plant science plays in the nation’s future. The product, according to Stacey, will be a strong, single message that can guide future funding for plant sciences. We encourage you to participate in the process. You can follow progress at www.aspb.org/ plantsummit and submit ideas there, or you can send suggestions to Leach (jan.leach@colostate. edu), Eversole (email@example.com), or Records (firstname.lastname@example.org). n
PPB Position Open with Regulatory Focus APS announces the availability of a position on the APS Public Policy Board (PPB) for a plant pathologist to focus on regulatory issues of interest to plant pathologists. For this position, PPB is particularly interested in plant pathologists with knowledge of regulatory issues at the EPA and APHIS. PPB seeks a person to continue productive initiatives related to regulatory issues, including the • establishment of an APS-APHIS partnership for risk-based regulations and e-Permitting to facilitate the movement of pathogens/pests intrastate and internationally; • identification of possible improvements in the risk-based permitting process for APS and associated societies; • efforts to provide the EPA with objective, science-based information for risk assessment on crop protection materials and biotechnology products for combating plant disease; and • submission of comments to USDA and the EPA on proposed regulations or guidances related to genetically engineered crops. Some newer areas of regulatory policy of interest to APS and PPB include • input on plant pathogens proposed for the Select Agent list; and • plant-pathology-relevant regulations from the U.S. Department of Health and Human Services (HHS) on synthetic biology. Interested individuals should review full details available at www.apsnet.org/ members/apsleadership/Pages/VolunteerOpenings.aspx. PPB requests submission by December 20 of a short statement of interest and background (short CV) from members interested in serving APS as a PPB board member.

Field Crops Rust Symposium This Month! The American Phytopathological Society has created the first Field Crops Rust Symposium to be held December 14–16, 2011, in San Antonio, TX. Make time for this important event—registration and housing are now open. “The FCRS is unique in its focus; it’s intended to provide presentations of cutting-edge research on the rust diseases, but should also facilitate the exchange of ideas beyond the typical crop specific discussions,” said Erick DeWolf, Kansas State University. “In recent years, new races of rust have emerged that are causing serious problems in wheat, corn, and soybeans. These diseases are causing yield losses valued at more than $100 million annually, and aggravate global shortages of grain. It’s essential that the scientific community comes together to address these disease problems— nothing less than global food supply is at stake,” he added. The keynote will be given by Philip Pardey, University of Minnesota, concerning “Rust diseases within the larger context of food security.” The lecture will help the audience understand the fundamental issues related to food security and the hazards impacting global food production. Registration is now open. Find more information and the full program schedule online at www.apsnet.org/fcrs. The symposium is targeted at the scientific community, but commodity leaders, crop consultants, and others will also benefit from attending. Be a part of this symposium, be a part of the solution. n

Looking Back at the History of UC-Berkeley’s Plant Pathology Department A copy of History of the Plant Pathology Department, University of California, Berkeley, 1903–1994, is now available in The Iowa State University Library Special Collections Department, home to the historical records of APS. This text includes the early history of agriculture in California and the role of the Experiment Station. According to Milt Schroth, many early documents were written by the chair and other faculty during the early days when diseases were rampant and the governor and legislature realized the importance of research and solving problems. Ralph Smith’s memoirs are also included in the book and are an interesting read. In fact, Smith started the first department of plant pathology in the country. To read more about this book or to purchase it online, visit www.blurb.com/bookstore/detail/2442774. APS works to maintain extensive historical resources through its historical archives on APSnet at www.apsnet.org/about/history.

People Student Degrees and Awards Marin Talbot Brewer completed the requirements for a Ph.D. degree in plant pathology at Cornell University in 2011. Her research was supervised by Michael Milgroom, with a focus on the population genetics and phylogeography Marin Talbot Brewer of the grape powdery mildew pathogen, Erysiphe necator. Using multilocus sequencing, Brewer demonstrated that E. necator populations in the eastern North America are highly diverse and are the likely center of origin for E. necator populations in Europe, Australia, and the Pacific Coast of the United States. She also identified mating-type genes in E. necator and several other powdery mildew species, including Blumeria graminis, Podosphaera spp., and Microsphaera syringae. She is currently an assistant professor in the Department of Plant Pathology at the University of Georgia, Athens. More about her research and opportunities for graduate, postgraduate, and visiting scholars can be seen at www.cals.cornell.edu/cals/plpath. Amara R. Dunn was the 2011 recipient of the Robert Gilmer Graduate Student Award. The award is named in honor of Robert M. Gilmer, a member of Cornell University’s (CU’s) Department of Plant Pathology at the Geneva Experiment Station from 1950 to 1975. Gilmer is remembered as an outstanding plant pathologist, colleague, and mentor, internationally respected for his contributions to our knowledge of virus diseases of fruit crops. His generous gift created the endowment that bears his name. Dunn received the award in recognition of her excellence in academics, research, and service to the Department of Plant Pathology and Plant-Microbe Biology. Her M.S. research on Phytophthora blight caused by the oomycete Phytophthora capsici was conducted at CU’s Department of Plant Pathology and Plant-Microbe Biology under the direction of Christine Smart.

Martin Dickman, director, Institute for Plant Genomics and Biotechnology, Texas A&M University, received the 2011 E. C. Stakman Award from the Department of Plant Pathology, University of Minnesota, in May 2011. The Martin Dickman award is granted to individuals of any country and nationality for outstanding achievements in plant pathology. Dickman has made numerous fundamental contributions to our understanding of fungalplant interactions. Early in his career, he recognized the potential of molecular and genetic approaches to address fundamental questions in host-pathogen interactions. His studies on the role of cyclic AMP and calcium in fungal development and the participation of signal transduction pathways involving various classes of protein kinases and phosphatases in pathogenesis are among the most thorough and significant contributions in this area of plant pathology. In his more current research, Dickman is beginning to elucidate mechanisms that regulate programmed cell death with the
goal of generating transgenic plants with novel mechanisms of pathogen resistance. His interest in potentially common mechanisms of infection by pathogens and common mechanisms of resistance led to his key participation in establishing the first national program in comparative microbiology, now a graduate program at the University of Nebraska. He truly embodies the qualities and spirit of the E. C. Stakman Award. Amy Y. Rossman, research leader, USDA-ARS, Systematic Mycology and Microbiology Laboratory, Beltsville, MD, was honored as the 2011 Distinguished Mycologist by the Mycological Society of America at their Amy Y. Rossman annual meeting in Fairbanks, AK. This award is given for her lifetime contributions to increased knowledge of the systematics of fungi, especially those of importance to agriculture and her contributions to the development of the U.S. National Fungus Collections and associated databases. South Dakota State University’s (SDSU’s) Soil Judging Team placed fourth overall, qualifying for the 2012 National American Society of Agronomy Soil Judging Contest at the Region 5 Collegiate Soil Judging Contest held in the Pierre and Fort Pierre area September 25–30, 2011. SDSU and the South Dakota Natural Resources Conservation Service hosted the event. Soil judging provides students with practical experience evaluating the physical and chemical properties of soils, important in making land-use decisions. Soil forming factors, which include site characteristics, soil classification, land-use interpretations, and soil morphology, are key parts of the judging process.
