Our laboratory is working in various areas of plant cell biology, molecular biology and genomics. It has focused on understanding disease-related and developmental phenomena that are of agricultural interest and developing methods to improve crops through biotechnology. Significant research accomplishments of the lab include:

  • Sequencing of the genome for bean (Phaseolus vulgaris) variety OAC Rex
  • Identification of molecular markers for: bacterial blight resistance in beans, lipoxygenase nulls and low linolenic acid content in soybean, Fusarium graminearum resistance in corn and yield-related traits in beans.
  • Development of molecular linkage maps for several bean, soybean and corn breeding populations.
  • Development of genetic distance and QTL- index based approaches to marker assisted selection.
  • Production of transgenic corn and tomatoes with improved resistance to fungal diseases.
  • Development of a genotype-independent Agrobacterium-based transformation system for corn.
  • Cloning and sequencing of genes from Brassica microspores that may be involved in the commitment of cells to embryogenesis.
  • Cloning and sequencing genes coding for structural and regulatory genes in the phenylpropanoid and folic acid synthesis pathways in Phaseolus.
  • Release of new white bean and kidney bean varieties developed through conventional breeding.
  • Measurement of the persistence of DNA from transgenic plants in agricultural soils.
