Study: Sorghum wards off pests by releasing hydrogen cyanide
Purdue Agriculture researchers have confirmed the long-held hypothesis that sorghum deters insects from feeding on its leaves by releasing hydrogen cyanide. Mitch Tuinstra, Agronomy, and Brian Dilkes, Horticulture and Landscape Architecture, found that insects preferred the leaves of a mutant sorghum plant with an abnormally slow release of cyanide to those of a wild-type sorghum plant with a normal cyanide-release rate. Fall army worms fed on the leaves of the mutant sorghum even though the leaves contained similar levels of dhurrin - the chemical compound responsible for synthesizing hydrogen cyanide - as those in normal sorghum plants. "This study separates for the first time the accumulation of dhurrin from the release of hydrogen cyanide," said Dilkes. "Both the mutant and normal sorghum plants contain dhurrin, but it's the rate of cyanide release that causes the insects to avoid one in favor of the other. It's a beautiful interaction between animal behavior and plant chemistry."

Bruce Bordelon was recognized as the recipient of the 2013 Outstanding Extension Specialist Award from the Purdue University Cooperative Extension Specialist Association at the Purdue Extension 2013 Professional Development Conference in West Lafayette, IN. This is a significant honor that reflects very positively on Bruce’s exceptionally effective Extension program. Bruce Bordelon is known particularly for his expertise on cultivar adaptation and small fruit crop management in the Midwest and eastern U.S.
Bruce Bordelon is a leader in the creation of regional peer-reviewed production manuals for commercial small fruit growers. He has made presentations on a variety of topics at more than 150 conferences and workshops during the past 22 years and has collaborated on many others, including the Purdue Grape and Wine Workshops, Indiana Wine Grape Symposium, the Indiana Horticultural Congress and the Heartland Grape and Wine Symposium. He has also led international Extension study courses for the wine grape industry to Italy, Chile and Argentina.
A member of the Purdue Wine Grape Team, Bruce has had a major role in the expansion, quality, and economic vitality of this industry in Indiana and the region. He is a respected international authority on grape pest management, evaluation of new grape varietals, and vineyard establishment and management practices. Bruce leads a research and Extension program with local, regional and national impacts on the wine grape industry. Bruce's research has benefited the wine industry in Indiana and the region; essentially all new plantings of grapes are of superior cultivars identified by his research. His research on Traminette has made it the most widely grown cultivar in the region. Since he initiated his work in 1991, the number of Indiana wineries has increased from a handful to more than 70 that now contribute in excess of $72 million to the Indiana economy.
Competition for this award is very strong, and Bruce’s selection reflects a clear confirmation of excellence by his Extension peers across the College of Agriculture.

From the Blackboard to the Whiteboard:
Plant molecular geneticist Burkhard Schulz didn't have to grow up in the digital age to understand technology's power as a teaching tool.
Schulz tapped into students' interest and expertise in digital technology by having them create instructional videos that explain topics in plant physiology and genetics.
The productions are used at Purdue summer outreach programs and as teaching resources in horticulture. They even garnered some international plant-biology video awards.
"Not a lot of people will flip through PowerPoint slides on their own, but have one of their friends say, 'You've got to see this video!' and you pretty much have them hook, line, and sinker," says Ellen Knapke, on of the student-producers.
Watch three student productions on YouTube: "PSI", "Pigment" and "Pressure Bomb".
Podcasts Enhance Student Experiences:
When Associate Professor Paul Siciliano takes students to England as part of a course on history, horticulture and landscape architecture, visiting various gardens is a key part of the curriculum. But it can be difficult to maintain contract with students in outdoor class settings.
A popular electronic tool -- podcasts -- turned out to be a solution.
Siciliano teamed up with Purdue's Department of Agricultural Communication to create podcasts that provide students with the information they need as they go through gardens at their own pace.
Siciliano tested the effectiveness of the new delivery method and found that students who used the podcasts scored higher on oral exams that students that didn't.

The innumerable contributions and distinguished career of Professor Jules Janick have again been recognized, this time by the award of Doctor Honoris Causa by the University of Agricultural Sciences and Veterinary Medicine, Cluj-Napoca, Romania. The Honorary Doctorate degree was conferred by the Rector of the University who noted Jules’ “exceptional achievements and his outstanding contribution to worldwide horticultural science and practices.”
This is the latest in a series of important recognitions of Jules’ contributions, culminating in 2009 in his induction into the “Hall of Fame” of the American Society for Horticultural Science. He has been similarly recognized by the University of Bologna, the Technical University of Lisbon, and the Hebrew University of Jerusalem.
