Research Project: Superior Resistance of Soybean to Pests and Pathogens Using Genetics and Functional Genomics

Location: Soybean Genomics & Improvement Laboratory

Project Number: 8042-21220-232-11-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Mar 30, 2011
End Date: Sep 30, 2013

The objective of this cooperative research project is to identify soybean genes homologous to Arabidopsis genes that are important in resistance of soybean to pests and pathogens and to develop soybean plants with broad resistance diseases and pests.

One of the major impediments to soybean growers is damage by pests and pathogens. Develop soybean with broad-spectrum resistance to a wide range of pests and pathogens using genetics and functional genomics. There is extensive knowledge of plant defense pathways leading to resistance to a multitude of pathogens, including fungi and bacteria, in the model system Arabidopsis thaliana. Using knowledge of Arabisopsis genes, we will clone homologous soybean genes encoding enzyems in the pathway leading to salicylic acid synthesis and on genes regulating salicylic acid synthesis and genes involved in the synthesis of jasmonic acid-related compounds and the regulation of that pathway. Over a multi-year period, we will determine which of these genes broaden resistance of soybeans against pests and pathogens.
