Engineering of Cotton Plant as a Safer Source of Protein and to Overcome Competition from Weeds
Speaker: Keerti S. Rathore, PhD, Professor of Crop Transformation at Texas A&M
Abstract
Cotton, the most important natural fiber crop, also produces enough seeds containing ~10 million tons of protein. A broader use of this resource for food and feed is hampered by the presence of toxic gossypol in the seed. Twenty-five years of work in my laboratory has culminated in selectively eliminating this toxin from the seed and obtaining deregulation from USDA-APHIS and FDA approval for its food/feed use. More recently, we have demonstrated the potential utility of the ptxD gene (encoding phosphite dehydrogenase) in transgenic cotton in combination with phosphite as a system to manage weeds that are becoming increasingly resistant to herbicides.

Speaker Bio
Dr. Keerti Rathore joined Texas A&M University in 1995. His early education was in India, followed by a Ph. D. from Imperial College, London in electrophysiology. While working at Purdue University as a postdoc, he switched to plant biotechnology in 1990. At Texas A&M University, he is utilizing the biotechnology tools (cell and tissue culture, genomics, transgenics and gene editing) to improve cotton, sorghum, rice and potato.
