Plant Developmental and Cell Biology
What controls cell growth and shape, how organ shape is regulated and how these developmental mechanisms affect plant growth in changing environment? To answer these questions, we need to identify key genes and how their protein products interact and function to support growth. We need to identify how environmental cues are integrated into signaling cascades that regulate growth and development. We use an integrated approach that includes molecular genetics, genomics, biochemistry, biophysics, imaging and modeling and use Arabidopsis, tobacco, tomato,yeast and E. coli as model organisms. Our studies focus on the plant family of RHO GTPases known as ROPs (Rho of Plants) or RACs and their effectors and on a specific subgroup of calcium binding proteins.
