New Office of Electronic Communications Director Darin Eastburn Intrigued by Advanced Technologies’ Role in APS

Darin M. Eastburn, associate professor of plant pathology in the Department of Crop Sciences, University of Illinois, Urbana-Champaign, became the third director of the Office of Electronic Communications (OEC) during the recent APS Annual Meeting in Austin, TX. Eastburn succeeds Jean Ristaino who served as director from 2002 to 2005.

Eastburn is looking forward to his new leadership role, “I think that the Office of Electronic Communications (OEC) is entering a period of transition. In the past, OEC and its predecessor the Electronic Technologies Advisory Group (ETAG) were instrumental in shaping the ways that APS members interact with the society and each other today. I can remember when APSnet was demonstrated for the first

time at an annual meeting, and there was a big effort to convince members that a society web page could be really beneficial for them. Now, with the online membership directory, career and placement center, and online journal access, the APSnet site has become the central hub for many of our society’s interactions. The idea of the online journals Plant Health Progress and Plant Health Instructor and the APSnet Education Center were initiated by OEC and ETAG. We can now register for the annual meetings, check job listings, order APS PRESS products, and read APS journal articles online, and none of that was possible just a few years ago. There have been a

Online Workshop on Methods to Detect Microbial Diversity in Soil The Scientific Programs Board of the APS is pleased to announce an online workshop to be held from July 15 through September 1, 2005 on Methods to Detect Microbial Diversity in Soil. Many methods exist for the characterization of soil microbial communities. Every approach may not be equally suited to test a particular hypothesis and there are costs and benefits associated with the use of each. Are you using the most efficient method for your objective? Are you getting the most out of your data? Could you delve more deeply by selecting a different method without increasing the cost of the project? Explore these issues with experts in the field and join in a discussion online on this timely topic.

The workshop will be moderated by Dilantha Fernando (Chair, APS Workshops). APS hopes to attract a diverse audience working on soil microbial diversity around the world, and will follow up with a discussion session on Wednesday, August 3, 2005 at the APS Annual Meeting in Austin, Texas. The workshop will continue online until September 1, 2005. Please visit and learn more about methods in detecting microbial diversity in soil at www.apsnet.org/online/soilmicrobes/ ■

number of issues that OEC, under the direction of Jim McDonald and Jean Ristaino, has dealt with, including the protection of copyright of electronically distributed materials, the move to electronic manuscript submission and review, the effects of electronic distribution of journals on the viability of paper versions and the financial viability of the society, and more recently the decision to grant free access to all journal articles two years after publication. Many of the projects that were initiated by OEC or ETAG have now matured, and the direct involvement of OEC has diminished as they have taken on a life of their own.”

So what is the future of OEC? According to Eastburn, “Technologies for electronic communications continue to advance, and it will be the role of OEC to evaluate these technologies and determine whether their adoption will benefit the members of our society. We are moving into an era of blogs, podcasts, RSS feeds, and wikis. Some of these may be useful for APS members and others not. I think that OEC can play a vital role in evaluating new ways of doing things and looking for ways to make new endeavors possible. At the APS meeting in Austin, we experimented with blogs and RSS feeds. Just to try things out and have a bit of fun, Gary Grove and David Schmale wrote blogs to chronicle their experiences at the meeting (visit http://aps.typepad.com/austin/). The idea was to give those who do not have the opportunity to attend the meetings a chance to hear about what goes on and to show how annual meetings can be very different things to different people. Whether blogs will become an important part of society interactions is not at all certain. We just began to test the waters with this one. However, using RSS feeds to update members on important events or news items is something that we will be looking at seriously. In addition, the APSnet website is continually being evaluated and upgraded to better meet the needs of the society, and OEC can act as a sounding board and evaluator of any potential changes. Not everything we have tried has caught on. The bulletin-board like features of APSnet Interactive have yet to generate a lot of interest among members, who appear to prefer the use of listservs or standard e-mails for group communication. We are currently looking at alternative approaches to electronic group communications to see if we can better facilitate this type of interaction. There are a lot of interesting developments taking place in the world of computer-based communications right now, and I think that it will be very exciting to help the society wade through this interesting mix of possibilities.”

Darin M. Eastburn received his B.S. degree in botany from Humboldt State University in 1981, and his M.S. and Ph.D. degrees in plant pathology from the University of California, Davis in 1984 and 1986, respectively. He worked as a post-doc for two years with Doug Gubler at UC Davis before joining the faculty of the Department of Plant Pathology at the University of Illinois in 1988 as an assistant professor and extension specialist in diseases of vegetable crops. He was promoted to associate professor in 1994, and received the college Faculty Achievement Award for Extension in 1998. During 1998–1999 Eastburn did a one-year sabbatical with David Shew at North Carolina State University, and upon returning to the University of Illinois, he accepted a research/teaching position in the Department of Crop Sciences. His research now focuses on soilborne fungi, primarily those that cause diseases of soybeans and on alternative plant disease control practices. He is responsible for teaching courses on plant pathogenic fungi, professionalism and ethics in the natural sciences, and an undergraduate general-education course, “Plants, Pathogens and People.” He also is involved in several scholarship of teaching and learning (SoTL) projects.

Eastburn is active in several facets of The American Phytopathological Society. He is completing a three-year term as the APSnet Features editor, serves on the editorial boards of the APSnet Education Center and Plant Health Progress, and is an ex-officio member of the Office of Public Affairs and Education (OPAE) and the Office of Electronic Communications (OEC). He has served as an associate editor for Plant Disease and as a senior editor for The Plant Health Instructor, as well as a member of several APS committees, including the Teaching, Mycology, Soilborne Diseases, and Illustrations committees and the Electronic Technology Advisory Group. ■

Public Policy Update

CSREES Compiles Success Stories in Plant Health Through PART InitiativeAnn Lichens-Park, National Program Leader, USDA-CSREES, apark@csrees.usda.gov

In the hustle and bustle of our busy lives, we do not often take time to reflect on the positive impact that our own work, or plant pathology in general, has had on the scientific community or the broader society. However, the productivity of U.S. agriculture, which is a result of generations of scientific endeavor, is envied around the world. About a year ago, the Cooperative State Research, Education and Extension Service (CSREES) of the U.S. Department of Agriculture (USDA) and the Public Policy Board of The American Phytopathological Society (APS) initiated an activity designed to provide APS members, and other interested individuals, an opportunity to reflect on significant accomplishments in the field of plant health and identify emerging scientific opportunities that should be exploited. The activity included a survey that asked respondents in APS and our sister scientific societies

to identify accomplishments and opportunities in plant health. The survey was made available via the APS website and open to any interested parties. A committee of APS members met just prior to the 2004 APS Annual Meeting to compile the results of the survey, such that the information could be presented at a workshop during the annual meeting. John L. Sherwood, Stella Coakley, and Ann Lichens-Park cochaired the committee. The committee members were Lynda Ciuffetti, Bill Dawson, Sheng Yang He, Gary Payne, and Sue Tolin. We also worked closely with Joyce Loper, a cochair of the Plant Pathology Priorities Committee, who kept us informed about the committee’s activities. The workshop was open to anyone interested in hearing about the survey results and/or commenting on them.

One of the successes identified was the early work by John Lindbo and William Dougherty on the elucidation of the mechanism of RNA-interference (RNAi), which came out of their attempts to develop plants with improved resistance to viruses. This work was funded, in part, by the Competitive Research Grants Office of the USDA Cooperative State Research Service (a predecessor of CSREES). As scientists learn more about RNAi, they are finding that it plays a critically important role in the physiology of a wide range of organisms, from plants to flies to humans. It is now being used as a tool for functional genomics studies, drug discovery, and disease therapy.

Other accomplishments include identification of novel plant disease resistance genes, better understanding of bacterial signaling mechanisms (quorum sensing), and improved understanding of how plant diseases spread. Opportunities identified include genomics of plants and microorganisms, advances in microbial ecology, and a better understanding of the economic impacts of plant diseases.

In March 2005, the plant protection portfolio of CSREES underwent a Program Assessment Rating Tool (PART) review, as required by the Office of Management and Budget. Lessons learned through the “Accomplishments and Opportunities Activity” with APS helped CSREES prepare for the PART review. The review was very successful, and we would like to thank everyone who provided input as part of the CSREES/APS activity. However, CSREES’s interest in hearing from APS members about accomplishments and opportunities in the field of plant health has not diminished with the completion of the PART review. In fact, this activity served to highlight the importance of continuing the dialog. We see a great need to improve our ability to document successes enabled by CSREES funding and to communicate them to stakeholders and the general public. Taking advantage of scientific opportunities can benefit the public in many ways. We need to clearly articulate these potential benefits. The probability that our efforts will be successful increases with each success story we hear. If you have success stories that you want to share or have questions about the survey or PART activity, please contact me at apark@csrees.usda.gov. ■

Northeast Forest Pathologist Workshop Held in New HampshireThe USDA Forest Service’s Durham field office hosted the Northeast Forest Pathologists Workshop at the Appalachian Mountain Club’s Highland Center, in the White Mountain National Forest, May 24–26, 2005. Cindy Ash, Margaret Miller-Weeks, Walter Shortle, and Kevin Smith worked together with Kyle Lombard from the state of New Hampshire to set up the program. Highlights included a Caliciopsis canker display, a full day in the field looking at tree diseases, and invited presentations on white pine diseases and ice storm damage. A late-season nor’easter made for a bit of rain on the field tour, but the participants were appreciative of the damper it put on black fly and mosquito activity! ■

PLANT MANAGEMENT NETWORK Celebrates 5th AnniversaryThe PLANT MANAGEMENT NETWORK (PMN) is celebrating its first five years of online publication. To commemorate the occasion, PMN took a look back—interviewing some of those involved when it began.

Started in July 2000 as a single journal, PMN now offers a full suite of applied science-based agricultural resources. Says Tim Murray, the first Plant Health Progress editor-in-chief and Washington State University plant pathologist, “As one of the web’s first electronic-only publications, I remember that when we first went online people wondered if it would last. After five years, I think the answer is definitely yes. Not only is the journal now part of the permanent literature, it has evolved into a comprehensive network for applied agriculture.” He adds, “People I talk with today can’t imagine not having this kind of hands-on information available electronically.”

Today, PMN offers three additional journals, Crop Management, Forage and Grazinglands, and Applied Turfgrass Science. In addition, it offers a unique set of other electronic resources, including a Soybean Rust Information Center, Image Database, Plant Science Database, Education & Training Center, B&C Tests, F&N Tests, and Commodity Variety Trials. “PMN is truly an innovative resource,” says Dick Stuckey, PMN advisory council chair and former executive vice president of the Council for Agricultural Science and Technology (CAST). “By providing so many tools in a single website, PMN offers a first-stop Internet address for those agricultural practitioners seeking reliable information.”

Since its inception, PMN has partnered with scientific and professional societies, land-grant universities, and agribusiness companies. Inaugural partners in 2000 were The American Phytopathological Society, the American Society of Agronomy, CAST, the Crop Science Society of America, and Syngenta Crop Protection. The partners program has grown to include nearly 50 of the most highly respected organizations in agriculture. PMN Director Miles Wimer says, “The PMN partners program is one of a kind in that it brings together over half of the land-grant colleges of agriculture and many nonprofit organizations and corporations. We hope to also engage international organizations and government agencies.”

PMN Land-Grant Partners Grow to 25!

Several units within the University of Minnesota’s College of Agriculture,

Food and Environmental Sciences and the University of Minnesota Libraries enthusiastically support their new PMN partnership. The College of Agricultural, Food and Environmental Sciences is consistently ranked among the top five colleges of agriculture in the world and is home to faculty and students who are recognized as global leaders in their fields. The departments in our college are dedicated to providing access to a high-quality education and helping citizens solve real-world problems and advance economically. We are also committed to preparing top-notch professionals to meet environmental, food, and agricultural systems needs and contributing to a broad public understanding regarding complex environmental, food, and agricultural issues. The University of Minnesota Libraries are among the university’s and the state’s greatest strategic assets. Housed in 5 major facilities and 11 branch sites on the 3 Twin Cities campuses, the libraries provide collections, access, and service to students, researchers, and citizens of Minnesota and beyond. The libraries are a vital intellectual partner in the experience of learning and discovery—at the University of Minnesota and throughout the world. ■

Society of Agronomy at the time that it and the Crop Science Society of America became partners, says, “I remember how progressive this all was when it started. It seemed the perfect vehicle to communicate the practical side of our research to advisers, growers, and the many other agricultural professionals that we serve.” Cardwell adds, “Over time, the cooperation among the various ag-related societies has been most fruitful, bringing forth added journals and resources. PMN is an excellent example of interdisciplinary collaboration that provides an integrated resource no one organization can produce on its own.”

Allison Tally, Syngenta Crop Protection’s partner representative to PMN, states, “I’m very proud that Syngenta was PMN’s first industry partner. PMN provides useful management information to agricultural practitioners in non-technical language. It also provides a forum for agribusiness companies to communicate information through PMN’s news and perspectives sections.” Tally, a soybean rust specialist, adds, “I’m also proud that Syngenta is a sponsor of the PMN soybean rust page. It’s one of the most comprehensive, yet concise, resources available and it’s overseen by a committee of experts to ensure its accuracy.”

The author of PMN’s very first research article, Gary Grove, Washington State University extension specialist, says, “It meant a great deal to me to have a refereed research article in the ‘launch’ edition of PMN’s journals. PMN is a great initiative and seeing it succeed is really rewarding.” PMN provides authors a distinct set of benefits, including peer-reviewed journal citations, rapid publication, worldwide readership, free use of color, and no page charges.

One of PMN’s earliest subscribers, Chris Becker, a certified crop adviser (CCA) and member of the National Alliance of Independent Crop Consultants, says, “PMN has become a major online resource for advisers. It has a clean user interface, no advertising, and is an abundant source of unbiased information—invaluable!” PMN has subscribers in more than 70 countries on all continents, in both temperate and tropical zones.

PMN is a not-for-profit effort that provides science-based solutions in agriculture. It seeks to sustain itself through subscriptions and partnerships in both the public and private sectors. For more information, visit www.plantmanagementnetwork.org. ■

9th Biennial Meeting of the Florida Phytopathological Society

The 9th Biennial Meeting of the Florida Phytopathological Society (FPS) was held May 2–4, 2005, at Mid-Florida Research and Education Center (MREC) in Apopka. The society was formed in 1989 to maintain and renew contacts and exchange news, views, and information with other plant pathologists in the state on a regular basis regarding plant disease issues and concerns that are relevant and often unique to Florida agriculture. The meeting was organized by Lawrence Datnoff (GNV Plant Pathology Department, former vice president and current

president of FPS), Erin Rosskopf (USDA-ARS, Ft. Pierce, former secretary and current vice president of FPS), and Don Hopkins (MREC director). Sponsors included BASF, BAYER, DuPont, Syngenta, and Valent Biosciences. Approximately 63 scientists, students, and industry personnel from UF/IFAS, USDA, the Division of Plant Industry, and industry attended the meeting. Approximately thirty-five technical papers were presented in five concurrent sessions: bacterial diseases (chaired by Dave Norman, MREC), fungal diseases (chaired by Phil Harmon, GNV Plant Pathology Department); virus & virus-like diseases I & II (chaired by Dennis Lewandowski, CREC, and Scott Adkins, USDA), and biological and chemical control (chaired by Richard Raid, EREC).

The opening general session included invited talks ranging from aerobiology to astrobiology: X. B. Yang, Department of Plant Pathology, Iowa State University, presented an “Update on the Status of Soybean Rust,” while A. Schuerger, Plant Pathology Department, Space Sciences Laboratory, Kennedy Space Center, presented “Microbial Ecology, Survival and Growth of Terrestrial Bacteria on Spacecraft Surfaces During Robotic Missions to Mars: Implications for the Future of Plant Pathology in Human Explorations of Mars.” Jay Scott, GCREC, provided a humorous monologue on “A Plant Breeder’s View of Plant Pathologists” during the evening banquet. Awards were also presented at the meeting, L. W. (Pete) Timmer received a Service Award in recognition of outstanding contributions to FPS, and Tom Kucharek received a Career Achievement Award in recognition of more than 30 years of outstanding contributions to plant pathology in Florida.

The graduate student research paper competition was organized and moderated by Carol Stiles (GNV Plant Pathology Department). Ten plant pathology graduate students participated. First, second, and third place received plaques and were given award checks at the dinner banquet during the meeting ($400, $300, and $200 were awarded for first, second, and third place, respectively). First place went to Matthew O. Brecht for “Ecology and Pathogenicity of Bipolaris and Curvularia spp. on Bermudagrass Putting Greens in Florida”; second place was awarded to Adriana Castañeda for “Functional Analysis of avr Homologues Found in Xanthomonas campestris pv. campestris Strain 528T”; and third place went to Wayne M.

alfalfa. She found that whereas quantitative (multigene) resistance was very sensitive to light levels, qualitative (single gene) resistance was not. This finding has significant implications for the field management of diseases where quantitative resistance is the only available form of resistance.

Following her work on Verticillium wilt, Pennypacker began a program on control of white mold on soybean, caused by Sclerotinia sclerotiorum. Presently, quantitative resistance is the only resistance to this pathogen. Thus, her previous research provided some insight into potential field control methods for white mold. Pennypacker conducted field research with cooperating farmers in an effort to find an agronomic control for white mold. She continued examining the host–pathogen system in greenhouse studies and discovered that, just as in alfalfa, soybean’s quantitative resistance to white mold was extremely sensitive to light levels. Field experiments appeared to indicate that soybeans planted in 21-in. rows at approximately 150,000 seeds per acre allowed plants to express quantitative resistance to white mold. The problem of drought during white mold studies was an ongoing challenge, because white mold prefers wet weather and this made replicating experiments difficult. Just after installing a mist system to address the water issue, Pennypacker was recruited to the position of assistant dean of the Graduate School at Penn State. The new administrative position marked the end of her research program but not her teaching.

Pennypacker assumed the position of assistant dean in 2002 but continued to teach Agro 555 “Effective Scientific Communication.” Her position in the graduate school primarily involved working with students with problems, facilitating enrichment activities for the university graduate student population, and developing professional development workshops for university faculty.

Pennypacker is a member of Sigma Xi, Phi Epsilon Phi, and Gamma Sigma Delta. She received the Richard R. Hill Award for Outstanding Contribution to Alfalfa Research in 1992. She is the author or coauthor of 26 refereed publications, 55 published abstracts, and 6 book chapters. She served as an associate editor for Phytopathology for 6 years and has reviewed manuscripts for 13 international journals. She also served as president of the Northeast Division of The American Phytopathological Society.

Pennypacker plans to remain in State College and continue teaching at Penn State and at the Mid-State Literacy Council, where she teaches in the English as a Second Language Program. She hopes to pursue her interest in drawing old barns, an endangered species in central Pennsylvania. ■
