Yesterday the Plant Pathology Graduate Student Organization hosted a Summer Kickoff Breakfast for all departmental members for their third year in a row. This year was potluck style with an emphasis on multicultural dishes. Lets hope after its third year this event sticks around because we love food.
In an effort to streamline processes, the Iowa State University Plant and Insect Diagnostic Clinic has updated and simplified submission forms for receiving requests for diagnosis for plant problems and insect, plant or mushroom identification.
ISU researchers are piecing together the genetic mechanisms that link plant growth and stress response. In a new paper, the research group links autophagy, an important energy recycling function, with slower growth during stress conditions. Autophagy plays a key role in animals as well as plants.
The apple-pumpkin bake off is one of our department's most anticipated events of the year, and boy did this year live up to the hype!
Recently, the Plant and Insect Diagnostic Clinic received samples of corn leaves with symptoms of tar spot from Jones County in eastern Iowa.
Dr. Steve Whitham, and his team of researchers, recently published findings in PLOS pathogens on how the soybean rust fungus interacts with the soybean plant to suppress immunity: "A Small Cysteine-Rich Protein from the Asian Soybean Rust Fungus, Phakopsora pachyrhizi, Suppresses Plant Immunity"
In the past 6 months, Dr. Mark Gleason has twice traveled to Belegrade, Serbia to deliver accelerated professional skills courses to the Faculty of Agriculture at the University of Belegrade, Serbia. In November of 2015, Dr. Gleason delivered an accelerated course on professional speaking skills, similar to PLP 590 he teaches here at Iowa State. More recently, in May of 2016, Dr. Gleason spent two weeks providing a short-course on research ethics, based on the GR ST 565 class he teaches here at ISU.
So far, this growing season has been relatively quiet on the crop disease front, likely due to the mild weather this spring has brought us....

With heavy hearts we say goodbye to another ISU plant pathology great. Dr. John Melvin Dunleavy passed away on May 19th at age 92.
“What we’re trying to achieve is a systems approach to crop production,” Beattie said. “Usually farmers and professionals just focus on one thing at a time. We want to get agronomists, meteorologists, even engineers to be a part of this so that we can work together to find what works.”
An interdisciplinary collaboration between Dr. Santosh Pandey (Electrical Engineering) and Dr. Gregory Tylka (Plant Pathology) was recently awarded a National Science Foundation (NSF) Instrument Development for Biological Research (IDBR) grant to develop an automated machine for soybean cyst nematode identification.
Abstract from award announcement:
Cassandra (Cassie) Wattenburger, a PhD student working with Dr. Larry Halverson, was recently awarded a highly competitive Fellowship from the 2016 National Science Foundation (NSF) Graduate Research Fellowship Program.
Dr. Roger Wise was recently elected to the rank of Fellow of the American Association for Advancement of Science (AAAS) and was honored during the AAAS Annual Meeting on February 13, in Washington, D.C
Compendium of Corn Diseases, Fourth Edition is now available through the APS Press website.
"This book provides the most current, practical information on the diagnosis and management of corn diseases"
Dr. Gary Munkvold, ISU Department of Plant Pathology and Microbiology and ISU Seed Science Center, is co-editor of this edition.
ICM News: The research showed winter cereal rye that grew an extra three weeks prior to soybeans produced about 300-400% more biomass (Fig. 1) with a 100% increase in nitrogen retention (Fig. 2), when compared with early terminated cover crops. Results from this study showed no difference in soybean yield following a cover crop killed three weeks prior to soybean planting compared to a cover crop that was killed one day before soybean planting.
Work from the Mueller and Leandro labs was recently featured as the Editor's pick in the January 2016 issue of Phytopathology.
