Technology to the rescue: Understanding courtship in plants

In many flowers, while the attractive part is the brightly colored petal, exquisite interactions between male and female structures are occurring further within the flower. These interactions ensure male (sperm cell) and female (egg cell) gametes come together, fuse, complete fertilization, and produce seeds. My lab is interested in understanding the molecular mechanisms (genes and bio molecules) that mediate these subtle interactions between male and female reproductive structures. Because such interactions occur deep within the plant tissues, it has complicated efforts to investigate them. In the up coming seminar, I will discuss three projects in my lab that utilizes interdisciplinary approaches (including computational modeling) to understand cell-cell interactions during plant reproduction.

I received my Bachelor of Science degree in Agriculture from Annamalai University, India in 1989 and also a Master\\\'s Degree in Plant Breeding and Genetics from Tamil Nadu Agriculture University, India in 1992. I then joined University of Georgia and obtained a Ph.D. in Genetics in 1998. From 1999-2003, I was a post doctoral fellow in Dr. Daphne Preuss lab at The University of Chicago. Subsequently, I was a Research Professional between 2004-2005, during which time I was the team leader of the pollen biology research group in Dr. Preuss lab. Since 2006, I have been a faculty in the school of Plant Sciences, University of Arizona.
