The wheat genetics and cytology research team has been identifying, characterizing, and utilizing economically and biologically important genes from relatives of wheat for wheat improvement. To date, we have developed spring wheat germplasm with resistance to FHB, rusts, tan spot, and SNB and potential tolerance to drought stresses from relatives of wheat. In addition, we have been characterizing some of the resistance genes, including molecular mapping and marker development for the genes. Recently we have identified genes for high nitrogen-use efficiency and nitrification inhibition in soil from wild relatives of wheat and been characterizing and incorporating these favorable genes into ND wheat backgrounds. In addition, we uncovered the cytological mechanism of meiotic restitution, a variant meiotic process that leads to polyploidization in wheat, and cloned a gene that may be involved in this meiotic process.
