Divisional Forum Meets with Northeastern 

Division to Discuss Engagement 

Jim E. Adaskaveg, Divisional Forum Chair, jim.adaskaveg@ucr.edu 

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 

Jim E. Adaskaveg undergraduate students to the field of plant pathology; and 3) increasing 

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. 

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. 

An annual APS Graduate Student 

Symposium proposal is also being 

developed by the Divisional Forum. 

This proposal is to have the winners of 

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

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 

Doug Jardine 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! 

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 

Thank You 

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. 

Special thanks to the more than 900 members who shared their skills, passion, and diverse 

perspectives this past year. Together, we are accomplishing significant goals for APS and furthering 

the plant pathology profession. 

According to the 2011 APS Membership Survey, members are eager to volunteer and the percentage 

of members who volunteer is growing. In addition, the amount of time members give is on the 

rise, and those indicating interest in participating in the future is also increasing, with early career 

professionals, along with student/post-doc members and those in developing countries, showing the 

most interest. 

What an impressive, dedicated community! Opportunities exist at various levels of engagement and 

across the full spectrum of the society. Make sure to share your talents with APS in the year ahead 

and continue to impact the future of plant pathology! n

COMMITTEE SPOTLIGHT 

Collections and 

Germplasm 

Committee 

Shuxian Li, Collections and Germplasm 

Committee Chair, shuxian.li@ars.usda.gov, 

and Rick Bennett, Collections 

and Germplasm Committee vice chair, 

rbennett@uark.edu 

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. 

Members of the committee sponsor 

symposia and workshops at APS meetings 

that address issues related to culture 

collections and germplasm and sponsored 

a hands-on workshop entitled “Microbial 

Collections: Practice and Management” 

on August 5, 2011, at the APS-IPPC Joint 

Meeting in Honolulu, HI. n

Public Policy Update 

PPB Attends Plant Science Research Summit 

Jan Leach, PPB Chair, jan.leach@colostate.edu 

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 (eversole@eversoleassociates.com), or Records (angela.records@gmail.com). 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. Please send to PPB Chair Jan Leach at jan.leach@colostate.

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

Management Practices 

for Dealing with 

Common Scab 

Common scab is a disease that can persist 

indefinitely in some soils and affects all varieties 

of potatoes. This unsightly disease causes 

lesions on tubers, which lowers marketability 

and increases the costs of production and 

processing. The latest Focus on Potato webcast 

by Thomas Zitter, professor of plant pathology 

at Cornell University, addresses common 

scab and best management practices to deal 

with the disease. This presentation will help 

users get a broad overview of common scab 

and understand its associated symptoms; 

become aware of the difference between

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. If you have information or materials that you would like added, 

please contact APS Historian Paul Peterson (ppeters@clemson.edu or +1.843.662.3526 ext. 133). n

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 

Marin Talbot Brewer and phylogeography 

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

2011. His research, 

supervised by Marc 

Fuchs, focused on 

the genetic variability 

of Grapevine fanleaf 

virus and the design Jonathan E. Oliver 

and testing of 

constructs for resistance. Oliver demonstrated 

that recombination and purifying selection 

are important evolutionary mechanisms in the 

genetic diversification of the virus and, using 

an agroinfiltration transient expression assay 

and stable transformants, identified varied 

concatenate constructs designed in conserved 

genomic regions that confer resistance to 

virus infection. He is currently a post-doctoral 

associate with Leonardo de la Fuente at 

Auburn University. More about his research 

and opportunities for graduate, postgraduate, 

and visiting scholars can be seen at www.cals.

Palle Pedersen have been recognized by 

the Crop Science Society of America for 

outstanding contributions to crop science 

research. Chilton, a distinguished science 

fellow at Syngenta, will receive the CSSA 

Presidential Award. Syngenta’s head of parent 

traits, Godshalk, was inducted into the CSSA’s 

2011 Class of 

Fellows. CSSA is also 

recognizing Pedersen, 

a seed care technology 

asset lead at Syngenta, 

with the 2011 Young 

Crop Scientist Award. 

The CSSA awards 

were presented at the 

society’s 2011 Awards 

Ceremony during its 

annual meeting held 

in October. 

Mary-Dell Chilton 

Brent Godshalk 

Palle Pedersen 

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 

Martin Dickman May 2011. The 

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.
