TEACHING:

BOT 1404  Plant Biology, beginning Fall 2007.  Prerequisite: BIOL 1114.  Morphology and anatomy of plants. Plant functioning: photosynthesis, water relations, translocation hormonal regulation, photoperiodism. Survey of the plant divisions, algae and fungi.  

RESEARCH:

My focus over the last few years has been to integrate phylogenetic and developmental genetic viewpoints through QTL and gene expression analysis. QTL analysis of the domestication of foxtail and pearl millet has been used to understand the genetic control of evolutionarily important characters such as branching and organ determinacy in the millet grasses. My recent work has used a comparative genomic approach to identifying candidate genes using maize developmental mutants and the rice genome, and to investigate interactions between genes and environment in the control of vegetative branching.
