Research Interests
Plant processes at cell, genome and molecular levels to improve plants for agriculture. The work has focused on developmental, disease-related phenomena and quality characteristics of agricultural interest.

Current Research
Molecular Characterization of Agronomic Plant Traits

  • molecular marker development for disease resistance, agronomic traits and quality traits in beans, corn and soybeans
  • isolation of genes related to secondary metabolite synthesis in bean
  • isolation of genes related to quality traits in soybean
  • identification of markers and genes related to Fusarium resistance in corn
  • examinations of genetic similarity in plant breeding populations


  • gene expression patterns during embryogenesis in Brassica napus microspore cultures
  • cloning and sequencing genes expressed during the early stages of embryogenesis in B. napus microspore cultures

Plant Transformation

  • Agrobacterium-mediated plant transformation of corn to increase disease resistance

Dry bean (Phaseolus vulgaris) breeding

  • variety development of white and coloured (kidney, cranberry) beans

Plant Bioproducts

  • investigations of the uses of plant fibres and proteins in the production of biocomposites and films

W.L. (Bill) Crosby is Professor of Biology at the University of Windsor, Ontario. Previously he has held the position of Director of Bioinformatics at the University of Saskatchewan, Senior Research Officer at the NRC Plant Biotechnology Institute (PBI) in Saskatoon, including multiple Adjunct Professor at the USask Faculty of Medicine and Faculty of Science. While at the PBI he held various posts including Department Head, Division Head and Program Leader for the PBI Plant Genomics Program from 1999-2002. In this role he directed development of the automation/robotics and bioinformatics facilities as the basis for the NRC s $5.3M Phase-2 program in plant genomics, involving over 18 research scientists. Crosby has authored over 65 peer reviewed publications, over 75 research articles and is the co-author of 3 issued patents. He is appointed to diverse national and international advisory bodies concerned with plant functional genomics and is the Canadian representative to both the Arabidopsis Multinational Steering Committee as well as the NSF international advisory groups. The bioinformatics activity of the Crosby group has included a lead role in two successful Genome Canada awards in the areas of Plant Functional Genomics ($19.5M) and Bioinformatics Platform ($10M).
