Current Research Interests:

The microtubule and microfilament cytoskeleton is essential for many dynamic cellular process including: cell division, cytoplasmic streaming, cellular architecture and morphogenesis. The ultimate goal for our research is to analyze the regulatory and structural molecules associated with these cytoskeletal elements and to discover how these contribute to plant development. We have developed two complementary strategies for identifying and characterizing the components necessary for cell division and morphogenesis. The first, a cytological and molecular genetic analysis of cell division, makes use of a large collection of maize meiotic mutants. The second approach is to isolate actin-associated proteins using molecular and biochemical techniques, to characterize their function in vitro, and to use these as probes to dissect cytoskeletal function in living plant cells.
