My research interests are focusing on the identification and characterization of quantitative trait loci (QTL) associated with resistance to soybean cyst nematode (SCN, Heterodera glycines Ichinohe) and soybean rust (SBR, Phakopsora pachyrhizi). Using marker-assisted backcrossing (MAB) and recombinant inbred lines (RIL), I am developing near-isogenic lines (NILs), which will be utilized for subsequent fine-mapping of identified QTL. These results, in turn, will enable to conduct positional cloning of candidate genes conveying resistance to the pathogens above mentioned.

In collaboration with other colleagues, I am also interested in the development of molecular genetic markers, such as simple sequence repeat (SSR) and single nucleotide polymorphisms (SNP), that are associated with the traits of interest and useful for marker-assisted selection (MAS). In addition, I am coordinating a study of transcription factors (TFs) and Affymetrix GeneChip profiling in attempts to understand the regulatory mechanism of SCN resistance and identify gene(s) underlying this trait in soybean.
