Translational and comparative approaches that exploit relatively rapid discovery in model biological systems and the large body of knowledge from other grass taxa can be applied to energy crops. This project will enable these approaches through alignment of switchgrass genetic maps and EST collections with reference grass genomes and will be a fundamental means by which the identification of switchgrass orthologs of genes in other species can be identified. This will allow candidate gene selection for genetic studies directly in phenotypically diverse switchgrass populations for QTL and association analysis. Based on the outcome of forward and reverse genetic experiments in Brachypodium designed to elucidate cell wall composition, the prospects of applying transgenic approaches in switchgrass to manipulate these qualities can be intelligently assessed. These approaches will produce uniquely defined genetic stocks in switchgrass significantly altered with respect to digestibility, that may be subsequently assessed via several different technology platforms for conversion efficiency to useful simple sugars, heat, or combustion gases.
