Area of Expertise: Molecular Genetics

Stress Physiology

A broad program based on the techniques of in vitro plant cell culture and selection with three major goals: 1) Establish cell systems to study the physiology and biochemistry of variants with increased tolerance to water and salt stress and isolate and study genes involved in cellular tolerance. 2) Regenerate plants in some instances from variant cell lines to attempt recovery of agriculturally useful phenotypes and to study the genetic basis of the phenotype of variants. 3) Estimate the extent and usefulness of phenotypic variability resulting from adventitious morphogenesis in plants.v
