We will utilize a systems biology approach to develop new breeding tools for perennial grasses and apply those tools toward improving switchgrass. Specifically, we will employ two complementary approaches to overcome the difficulty of breeding a large, polyploid, self incompatible plant. The first approach will accelerate conventional breeding by developing a method to rapidly create doubled haploid lines to create fully homozygous lines for breeding. The second approach is to develop tools and reagents to accelerate the biotechnological improvement of switchgrass including: modules for improved stress tolerance, a test bed to evaluate transgenes in a perennial model grass and a robust gene containment system. This relates to objective 2 of the inhouse parent project, "Objective 2: Identify and demonstrate the utility of crop-derived gene expression control elements(promoters/enhancers/terminators/insulators) that facilitate trait development in crop plants"
