Functional Genomics of Legume Nutrient Acquisition

This projects focuses on whole-genome analysis of transcripts expressed during plant response to the stress of low nutrient availability. The expression of genes that respond in legume roots and root nodules to low phosphorus, nitrogen, and/or iron are evaluated. The species include Lupinus, Phaseolus, and Medicago. Affymetrix GeneChips and RNA-seq are used to analyze the expression of genes as plants adapt to nutrient stress. The project also includes assessment of whether single nucleotide polymorphisms occur in genes of interest and if molecular markers can defined from RNA-sequence data. The project also includes genomic analysis of seed transcripts in soybean seed development and analysis of soybean fast neutron mutants.
