Update on the APS Initiative to Establish a National Culture Collection SystemRick Bennett, APS Public Policy Board Member, [email protected]
For over a year now, the APS Public Policy Board (PPB) has supported the formation of a National Plant Microbial Germplasm System (NPMGS). This emphasis comes on the heels of two workshops and a strategic plan developed by an APS ad hoc committee in which a structure and framework were defined (see PPB website, www.apsnet.org/members/ppb, for the full report). The PPB will be traveling to Washington, DC, again this March 2010 to advocate for support from administrators and policy makers to launch the new system.
As researchers and educators, we know that culture collections of plant-associated microbes represent an essential resource foundation for U.S. science. Microbial collections are used to solve a myriad of practical
challenges to our agricultural and environmental systems and play diverse and critical roles in understanding plant resistance to diseases. These public and privately held resources provide a critical link between past and present disease epidemics and facilitate identification of emerging diseases. They also support U.S. cooperation in international efforts to map and understand the global diversity and dynamics of economically and environmentally significant microbes.
Our microbial culture collections are at risk, however, as the United States lacks a coordinated national system to protect, preserve, enhance, and facilitate the use of these valuable resources. Plant-associated microbes and pathogens are maintained currently in large, geographically dispersed collections in federal research laboratories, academic institutions, and commercial facilities. Often, funding for collection curation and maintenance is spotty, short term, and/or uncertain. Without a long-term management plan, collection preservation and quality assurance will become more and more endangered. Further, a common database cataloguing the content of individual collections in a uniform manner is needed to ensure culture accessibility and utility. The lack of adequate and organized collection information also hinders active engagement in international microbial diversity endeavors.
The 2010 Readership Survey Is on Its Way! Can’t wait for the newest issue of Phytopathology News to arrive each month? Then you’re not alone. Members often cite Phytopathology News as one of the top APS membership benefits. To ensure your continued satisfaction with the publication, we need your input.

Editor’s CornerRise to Rebellion (Or, Was It Just Luck?)Doug Jardine, Kansas State University, [email protected]
The title of this column refers to the 2001 New York Times bestseller Rise to Rebellion by famed author-historian, Jeff Shaara. As I read the Letter to the Editor in the January issue of Phytopathology entitled, The Society That Almost Wasn’t: Issues of Professional Identity and the Creation of The American Phytopathological Society in 1908, by Paul Peterson and Karen Beth Scholthof, I was reminded of the struggle of the Founding Fathers and the dramatic saga of the birth of the United States of America. While certainly no one’s life would be on the line for treason in the December 1908 meeting held at the USDA building in Washington, DC, as was the case for John Adams, Thomas Jefferson, Benjamin Franklin, et al., as they met in Philadelphia in 1776, the strong differences of opinion among the plant pathologists at that meeting mirrors the disagreement among the Founding Fathers as to the wisdom and necessity to declare independence
from England. So, too, our society’s founders were faced with separation—should a separate phytopathological society be formed?
In their recent letter, Peterson and Scholthof write, “After a lively discussion, the committee’s recommendation to create a society was put to a full vote. It passed by a margin of 32 to 12, again demonstrating that there was considerable objection to forming this new society.”
If you have not yet read their letter, I encourage you take the time to do so. Rather than being members of The American Phytopathological Society, we could easily have all been members of the Botanical Society of America or members of Section G of the American Association for the Advancement of Science, as these were potential homes for plant pathologists suggested by some of the dissenters. What if the dissenters had prevailed? I would encourage everyone looking for a good read to seek out Shaara’s book and its sequel, The Glorious Cause, set during the Revolutionary War and written from the point of view of George Washington, Nathanael Greene, Ben Franklin, British General Charles Cornwallis, and many others. Shaara makes it clear that, while patriotism, courage, and determination played important roles in the struggle for American independence, in the end, luck may have been the deciding factor in victory. Undoubtedly, we too are lucky that the separatists at that 1908 meeting won out, thus paving the way to create the society, that now, as we enter our second 100 years, has become “the premier society dedicated to high-quality, innovative plant pathology research.” n

Federal funding for an NPMGS is needed to preserve these irreplaceable and invaluable resources. A viable and well-coordinated national system that safeguards access to the diversity of plant-associated microbes and enhances their utility in the scientific community will facilitate research and education focused on a wide range of practical problems. The NPMGS will consist of distributed, expert-curated, taxon-specific repositories at various locations, linked through a searchable common cyber-database that is networked and quality-monitored by a coordinated administrative framework and supported by a central physical repository of back-up collections. This cost-effective system will ensure that reference strains are not lost, but remain accessible by the broader scientific community. The infrastructure for this national system will be connected to active, existing research programs at federal and academic institutions through a joint venture between the federal government initiative, existing structures, such as the U.S. National Plant Germplasm System, and existing university and industry programs.
Protecting these resources is core to our mission to benefit science and society. We need your help if we are going to be successful in creating the NPMGS. Please advocate for this initiative with your colleagues, supervisors, administrators, and members of congress. Your success stories and missed opportunities related to culture collections can be extremely helpful in our advocacy efforts, especially if they relate to major federal initiatives (e.g., food safety, human health and safety, food security, biofuels, etc.). Please share any ideas with us that will make our case for funding stronger in Washington.
Contact Rick Bennett ([email protected]), Jacque Fletcher ([email protected]), or Kellye Eversole ([email protected]) with questions or comments and to find out how you can help bring the NPMGS to fruition. n

Private Practice as a Career ChoiceI just read the recent paper on “Education in Plant Pathology: Present Status and Future Challenges.” An impressive group of people evaluated limited data and did a wonderful job of summarizing the data in every possible light. I can see why it is one of the top nine papers of 2009 in Plant Disease. I would just like to add a thought about not even discussing or collecting data on a career in private practice. Most medical doctors and veterinarians have private practices. To my knowledge, only four plant pathologists in the United States have a private practice. There are several others who do a little consulting, but only four full-time plant pathologists have a private practice as their sole means of financial support. What is wrong with this picture? Extension services have been cut all across the country and growers and others are in need of this kind of service. It is an exciting and very profitable business and it does not even get mentioned. I have given several seminars on starting such a business and I always get standing-room-only attendance at our national meetings or at universities where I have been invited to speak. What does it take for plant pathologists to have the courage to start something already established by our colleagues dealing with humans or animals? It starts with informing students that there is more to a career choice than universities, government, and private companies. Perhaps we are finding a lack of students because we are experiencing a fall out from being so efficient in agriculture that few are involved in the science and practice anymore. We always present this as a positive fact that only we seem to appreciate. All the public knows is that we have an abundance of good food in the markets.

Read a Fast-Breaking Paper
“Emerging concepts in effector biology of plant-associated organisms” by Saskia Hogenhout, Renier Van der Hoorn, Ryohei Terauchi, and Sophien Kamoun, has been identified
as a “Fast-Breaking Paper” in the category of Plant and Animal Science by Thomson Reuters ScienceWatch. This distinction comes because it is one of the most-cited papers in its discipline published during the past two years. Read it in MPMI Online at http://apsjournals.apsnet.org/doi/abs/10.1094/MPMI-22-2-0115. n
Second National Meeting of NPDN, December 2009Ray Hammerschmidt, Michigan State University, [email protected]
The warm weather of Miami was only one of the attractions that drew more than 200 attendees to the second National Plant Diagnostic Network (NPDN) meeting sponsored by NPDN and held December 7–9, 2009. Attendees included diagnosticians from land-grant university and state
department of agriculture labs, university and USDA scientists, and individuals from the private sector who are interested in plant diagnostics.
A premeeting tour to the Fairchild Tropical Botanic Garden kicked off the meeting, which consisted of several symposia and workshops and was held at the Intercontinental Hotel.
More than 35 talks and workshop sessions covered a wide array of topics of interest to diagnosticians and those engaged in plant diagnostics, plant disease, and pest regulatory concerns. A plenary session on issues related to plant biosecurity was followed by symposia on new and emerging threats, genomic tools and resources for pest identification, and novel techniques for detection and surveillance. The symposia were complemented with workshops on technology tools and the NPDN and on Spodoptera identification. Activities of NPDN committees, regions, and individual diagnostic labs were highlighted at a poster session. The meeting venue provided great opportunities for attendees to discuss diagnostics, new pests and pathogens, and issues related to plant health. The meeting concluded with regional meetings where topics of interest to each of the NPDN regions were discussed.
A postmeeting production agriculture and greenhouse tour capped off a very successful meeting. The third NPDN national meeting is in the planning stages for late 2011.
For more information on all that happened at the second NPDN national meeting, as well as pdf files of all poster presentation, visit the NPDN website (www.NPDN.org). n

RFP: Funding for Research on Sudden Oak DeathSudden oak death (SOD), caused by the exotic, invasive pathogen Phytphthora ramorum, continues to spread in the coastal forests of California and Oregon. From 2001 through 2009, the USDA Forest Service, Pacific Southwest Research Station, has funded more than $11 million in research on SOD. Results from this research have provided much of our fundamental understanding of this pathogen and served as the basis for monitoring, management, and regulatory practices. However, additional information is needed on the biology, epidemiology, and behavior of P. ramorum (development of new treatment strategies; pathogenicity and resistance; and short- and long-range spread) if we are to effectively minimize the pathogen’s ecological, social, and economic impacts.
Approximately $500,000 will be available in summer 2010 to fund new projects. Multiyear, collaborative projects are encouraged. Proposals are due March 31, 2010. Questions should be addressed to Susan Frankel, USDA Forest Service ([email protected]). More information is also available online at www.fs.fed.us/psw. n
Funding OpportunityHow Do YOU Get the Word Out?
APS member Kevin Ong is an associate professor and extension plant pathologist and director of the Texas Plant Disease Diagnostic Laboratory, College Station, TX. But, you may also recognize his Twitter name, txplantclinic, because his posts
are regularly quite informative and, perhaps, twitillating.
I hear that you are quite involved with Twitter, Kevin.
I tweet and Facebook for the Texas Plant Disease Diagnostic Lab (TPDDL)
(txplantclinic). I use social media as a tool to market and to disseminate information about and for the TPDDL. To me, it is a tool more to get the word out about plant pathology and plant pathology issues to the general population.
Do you see Twitter as an advantageous networking tool?
As for networking, it depends on how you define “networking.” I think both Twitter
and Facebook are great tools for networking—if that means being able to get the word out to all listening parties, i.e., like a bulletin board. Facebook is better to encourage interaction between participants, but I think it is something that many of us plant pathologists may not have the time for. Even I can’t always keep up with the APS Facebook page. I also follow some other colleagues’ tweets to see what they are up to. I think social media are good tools, but I am not so sure that it can provide a virtual place for a pathologist to truly network. That is why affordable and interesting annual meetings are still important!
Check out Ong’s and other’s tweets (via re-tweets) at the APS Twitter site (http://twitter.com/plantdisease), where APS has nearly 300 followers. n

Widely Prevalent Pathogen by State Lists DevelopedJames L. White, USDA APHIS PPQ, [email protected]
Since 1992, USDA’s Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) unit has worked with APS’s Virology Committee (especially John Hill, Iowa State University) to prepare a list of widely prevalent viruses by state. APHIS has provided funding to the committee to defer costs and help support travel costs for speakers to committee-sponsored symposia. Subsequently, widely prevalent bacteria and fungi lists were prepared by their respective committees. With the assistance of Joe LaForest of the Bugwood Network at the University of Georgia’s Center for Invasive Species & Ecosystem Health, the lists are now available online at www.prevalentfungi.org, www.prevalentbacteria.org, and www.prevalentviruses.org. Besides their state distribution, the sites contain alternative scientific names, common names of diseases, current taxonomy, and links to taxonomy reference sites. In addition, the Bugwood image database is linked to the listed organisms, providing easy access to images that can be downloaded for teaching purposes. Scientists can also upload new images. APS is currently developing a widely prevalent list for plant-pathogenic nematodes and the Entomology Society of America is considering developing lists of arthropods. The current committee chairs are Rodrigo Valverde (virology), Carol Stiles (fungi), George Bird (nematodes), and Norm Schaad (bacteriology). The names of the regional coordinators who are responsible for developing the state lists can be found on each website.
APHIS also uses the widely prevalent lists to expedite PPQ 526 permits. APHIS sends the widely prevalent pathogen lists with standard conditions to every state and territory and asks if they would agree to expedite the review of the listed organisms. More than 40 states participate in expedited permitting. The states and organisms that qualify, and procedures to submit these permits, can be found at www.aphis.usda.gov/plant_health/permits/organism/wpp/index.shtml. n
International Phytophthora capsici Conference The Second International Phytophthora capsici Conference was held at Duck Key in the Florida Keys, December 1–2, 2009. The conference convened scientists from all over the United States and internationally to exchange current research on Phytophthora capsici, a pathogen that has become a serious threat to the U.S. vegetable industry nationwide.
Fifty-five registered participants listened to 23 presentations ranging from grower experiences with disease to more technical aspects of disease management, epidemiology, genetics, and host resistance. In addition, eight posters were displayed describing research on new fungicide chemistry, resistance management, and fungal genetics. Presentations were followed by lively discussions that spilled out to the breaks and receptions that were held near the dolphin training pools and tidal salt water pool.
The conference was organized by the University of Florida and the University of Georgia and generously supported by Agriquest, BASF, DuPont, Syngenta, and Valent.
The next conference has been scheduled to convene in December 2011 in the Florida Keys. Those who are interested in learning more about the meeting may visit http://conferences.dce.ufl.edu/pcap/reg.aspx or contact Pam Roberts ([email protected]) or Alex Csinos ([email protected]). n
Foundation for Plant Doctor Education LaunchedA new Plant Doctor Education Foundation (PDEF) has been established to help support the Doctor of Plant Medicine Program at the University of Florida, the Doctor of Plant Health Program at the University of Nebraska-Lincoln, and other similar programs to be developed in the future.
Ken Bader, CEO of Global Agribusiness, former professor of agronomy and dean of students at The Ohio State University and vice chancellor at the University of Nebraska, has been named executive director. Bader says, “I think it’s terrific the program is being offered at a Southern and a Midwestern location. Both regions have unique plants and cropping systems, so these universities are able to tailor their programs to their geographic areas.” Representatives of PDEF are planning to meet with agribusinesses to develop funding plans and projects in which they can become involved. Funds will be used to pay for fellowships, internships, student travel, and program support. For more information on PDEF, contact Bob McGovern ([email protected]). n

Citrus Greening Conference Proceedings Published on PMN
Huanglongbing (HLB), or citrus greening disease, a major threat to citrus crops native to Asia nearly a century ago, has rapidly globalized in recent years,
devastating citrus crops in North and South America, Europe, Africa, and other areas of the world. Responding to this alarming threat in the citrus industry, the international research community invited colleagues, regulatory agency representatives, and commercial industry leaders to exchange the latest information, knowledge, ideas, and concepts related to citrus greening. The comprehensive 420-page proceedings of this meeting, called the International Research Conference on Huanglongbing, held in Orlando, FL, in December 2008, has been published for online public viewing on the Plant Management Network (PMN) website. The proceedings of this conference, which attracted 427 participants from 27 countries, contained nearly 150 papers from 14 sessions, all freely accessible online. The papers feature reports, case studies, research findings, summaries, and perspectives on many aspects of the disease from researchers, industry, and regulatory agencies.
Session titles included Detection and Diagnosis; Epidemiology; Economics, Fruit Quality, Crop Loss; HLB Management Strategies; and International Citrus Industries: Coping with HLB. The proceedings also include keynote lectures from noted international experts with nearly 100 years of combined expertise with HLB, key take-home messages, a survey of research priorities from participants, agendas, and more. This entire collection of information can be found at www.plantmanagementnetwork.org/hlb, where viewers can access papers individually or download the entire proceedings as a single .pdf file.

Interested in Having an Influence on Public Policy in DC? The American Phytopathological Society Public Policy Board (APS PPB) is pleased to announce a call for applications for the fifth annual PPB Early Career Internship. The internship, which is open to APS early career members (current graduate students or post-doctoral associates and junior professionals), allows a young plant pathologist to participate in PPB activities during 2010–2011. The internship will begin immediately following the 2010 APS Annual Meeting and will terminate at the end of the 2011 APS Annual Meeting. The goal of the Early Career Internship is to provide an opportunity for the selected individual to gain hands-on experience in public policy at the national level that relates generally to agricultural science and specifically to matters of interest to APS. By working with APS PPB, the intern will learn how scientific societies, nongovernmental organizations (NGOs), executive branch agencies (e.g., USDA, NSF, and EPA), and the legislative branch interact in crafting public policy. The 2010 intern should be able to attend the midyear governmental outreach meeting of the APS PPB in Washington, DC, in late February or early March 2011 (dates TBA). The intern’s travel costs for this activity will be covered. In addition, the intern should attend the APS PPB annual business meeting to be held in conjunction with the APS annual meeting. Following the internship year, the intern will prepare a written and/or oral report on the experience for delivery to the APS PPB and membership. Other activities may include, but are not limited to, the following: • Participating in PPB monthly conference calls and policy agenda-setting meetings; • Assisting PPB with development, tracking, and analysis of relevant policy issues; and • Assisting PPB with planning Capitol Hill and agency briefings.
Application Process Applications should be submitted as one portable document file (PDF file) saved as last name, first initial (example: SmithT_internship.pdf), and include all of the items described below. All application materials must be received by March 31, 2010, and should be sent to Jacqueline Fletcher, Public Policy Board Chair, Department of Entomology and Plant Pathology, Oklahoma State University, Stillwater, OK 74078 U.S.A.

Student Awards/Degrees
Several students fulfilled requirements for graduate degrees in the Department of Plant Pathology at the University of Georgia (UGA) during fall semester 2009. Jeff Garton completed his M.S. degree under the guidance of David Langston. In his thesis “Evaluation of
race and copper tolerant strains of Xanthomonas axonopodis pv. vesicatoria, causal agent of bacterial leaf spot of bell pepper in Georgia,” Garton discovered that resistance to copper among strains of the bacterial spot pathogen is quantitative and can vary across strains from a single location. He also determined that the dominant race of the pathogen in Georgia is race 10, a race to which no commercial cultivars have resistance. His research was awarded with the E. Broadus Browne Award for Outstanding Graduate Research from the UGA College of Agricultural and Environmental Sciences. He currently manages Copper Station Farms, a 370-acre operation growing southern highbush and rabbiteye blueberries in McIntosh County, GA. Chris Martin received the masters in plant protection and pest management (MPPPM) degree with Jim Noe as his program advisor. The MPPPM, a professional, nonthesis degree program, produces graduates with comprehensive, multidisciplinary training in integrated pest management of insect, plant disease, and weed pests of agricultural, commercial, and home commodities. As part of the program, Martin interned with Jean Williams-Woodward on Phytophthora ramorum monitoring for the state of Georgia, and on evaluating fungicides for control of Pythium
aphanidermatum on greenhouse crops. Martin is now employed by the U.S. Forest Service, Southern Research Station, where he is working in the lab of Bill Otrosina. Marina Nadal received her Ph.D. degree under the direction of
PeopleScott Gold with a dissertation entitled “Exploring the roles of autophagy and cell wall degrading enzymes in the life cycle and pathogenic development of the basidiomycete fungal plant pathogen, Ustilago maydis.” Her research was awarded with a Dissertation Completion Award from the UGA Graduate School and the Kenneth Papa Award for Outstanding Graduate Student Research from the Georgia Association of Plant Pathologists (GAPP). Nadal has joined the Fungal Physiology Group at the University
of Utrecht in the Netherlands as a post-doctoral researcher to investigate physiology, transcription regulation, and extracellular enzymes in fungi. Johanna Takach earned her Ph.D. degree under the direction of Gold. Her dissertation, “Analysis of genes involved in
developmental pathways in two basidiomycetous fungi, Ustilago maydis and Sclerotium rolfsii,” explored the roles of additional components in the cAMP/PKA pathway in the model system U. maydis and identified genes differentially expressed during sclerotium development in S. rolfsii. She was a recipient of the Storkan-Hanes-McCaslin Award and the GAPP-sponsored Kenneth Papa Award for Outstanding Graduate Student Research for her research activities. Takach is currently employed as a post-doctoral research fellow in the Forage Improvement Division of the Samuel Roberts Noble Foundation in Ardmore, OK.
Awards
Blair Buckley, Zhi-Yuan Chen, Patrick Colyer, Clayton Hollier, Boyd Padgett, and Raymond Schneider were recipients of the Tipton Team Research Award presented on December 14, 2009. They won this prestigious award for their seminal role in the first discovery of Asian soybean rust (ASR) in the continental United States and for preparing Louisiana and the nation to deal with this now perennial threat to soybean productivity. This award was established by the Louisiana State University (LSU) AgCenter to recognize significant
contributions to Louisiana agriculture by a team of scientists in the past five years who have been participants in exceptional collaborative research efforts that would not have been possible by the scientists acting alone. They showed outstanding initiative and leadership in addressing the challenges of ASR. Within days of the initial discovery, they led an aggressive survey of Louisiana parishes for rust on volunteer soybean, kudzu, and other potential hosts. They hosted a rust identification workshop and produced resin-embedded rust-infected soybean leaves that were distributed nationwide as a visual aid in diagnosis. They recorded the first aerial spore find of ASR in 2005 and developed new technology to improve spore-trapping. Research programs for screening and evaluating fungicides and the U.S. soybean germplasm collection for resistance to ASR were initiated at multiple locations in Louisiana. Results from their proteomics studies revealed important biological information as it relates to early events in the ASR infection cycle. Based on all aforementioned, this team set a national standard for cooperation, professionalism, and accomplishment.
John Leslie, professor and head of the plant pathology department at Kansas State University (KSU), has been awarded one of the American Society for Microbiology’s international professorships. The society has awarded Leslie an International Professorship for
Latin America. He will be a visiting professor at the Universidad Nacional de Rio Cuarto in Argentina, where he will help present the Fusarium Laboratory Workshop in March 2010. The workshop helps participants better understand Fusarium. Since 2000, Leslie has organized this international workshop, which takes place at KSU in odd years. As part of his professorship in Argentina, Leslie also will offer a scientific writing workshop based on material he has presented to nearly 3,000 people in 16 countries. Leslie’s broader research interests include biochemical, molecular, and population genetics of model and plant-pathogenic fungi.
