  • Our main objective is the development of finished “farmer ready” varieties, not germplasm.
  • We have effective support from our pathology and nemetology colleagues at Purdue. Since we began working with Scott Abney and Jamal Faghihi in 2001 100s of our breeding lines have been screened for Phytophthora and Soybean Cyst Nematode resistance. We also participate in cooperative university-based regional tests. Our main disease problems that we address, because they are the most important to Indiana farmers, are Phytophthora Root Rot, Soybean Cyst Nema. ( Heterodera glycines) , and Sudden Death Syndrome ( Fusarium) . Increased efficiency and accelerated breeding techniques were used to develop the first two varieties from the program. We have been able to release these varieties to Ag Alumni Seed Improvement Association, Inc. this year (2005) for foundation seed production. In total only 7 years will have past from the time when the cross was made until the day when seed of these NonGMO varieties can be sold to Indiana farmers. It is possible that there may be some small quantities of seed sold in 2006, which makes it technically only a 6 year development time.

    • Corn is a model of human immune disease: Repair of DNA hairpins
      • An unusual DNA structure is formed when the maize transposon Ac moves, ALSO forms while vertebrate animals make immune receptor genes.
        • Key factors for repairing these structures, required in humans, are absent in plants and yeast, yet all these organisms repair DNA hairpins very effectively. We are studying how this happens. (BARD-funded, NSF and NIH to be submitted shortly)
    • Maize genes that control starch digestibility (joint project with the Whistler Center for Carbohydrate Research at Purdue) (PRF and ARP-funded)
  • Dan Szymanski Understanding how plant cells use actin filament polymerization during growth In developing cells of the seed and germinating seedling, the polymerization of the actin cytoskeleton drives organelle biogenesis during cell growth. We are studying actin-dependent processes in order to manipulate the transport, metabolism, and storage of lipids. The actin related protein (Arp) 2/3 complex is an evolutionarily conserved group of proteins that efficiently nucleate new actin filament polymers. The grants below focus on different functional aspects of the Actin-related protein (Arp) 2/3 complex using the model plant Arabidopsis. NSF -Mechanisms of plant cell morphogenesis: ARP2/3 function and trichome distortion in Arabidopsis Objective: To determine which organelles are controlled by the Arp2/3 complex during growth. DOE - The Arabidopsis WAVE Complex: mechanisms of localized actin polymerization and growth Objective: To understand how the plant WAVE proteins control the activity of the Arp2/3 complex. Hughes Graduate Student Fellowship : 2003-2007 Regulation of the lipid content of soybean Objective: To understand how post-germination phospholipid trafficking in the cotyledon is regulated
