Areas of Specialization/Research

Seed Storage Protein Gene Regulation (bean phaseolin and rice glutelin):

  • Spatial and temporal control of gene expression

  • cis-acting transcriptional regulatory elements

  • trans-acting transcriptional activator/repressor proteins

  • Promoter mutant isolation in Arabidopsis thaliana

Structural Analysis and Nutritional Improvement of bean phaseolin:

  • Structure-based protein design and computer simulation

  • Heterologous protein expression and structural analysis

  • Methionine/lysine enhancement and protein digestibility

  • Protein folding, glycosylation, trimer formation and packaging

Crop Improvement through Transgenic Research (Rice, Bean, Cotton, and Sugarcane)

  • Leguminous protein expression in transgenic rice and beans

  • Enhanced resistance to herbicide, disease and insect pests

  • Medicinal protein production
