Molecular Genetics of Floral Development

We are exploring the role of genes in the floral symmetry gene network (FSGN) on stamen development and breeding system evolution. The floral symmetry gene networks affect both the shape and the development of male and female parts within flowers. Our preliminary results from Antirrhinum suggest that genes in the FSGN may also influence the timing of male and female phase expression with a flower. We are now using CYCLOIDEA as a candidate gene to conduct RT PCR expression and development studies in Collinsia. In addition, we are investigation CYCLOIDEA gene evolution and duplication in the genus Collinsia. These projects are collaborative with Tingshuang Yi and Lena Hileman.
