(1) How did the ancestral cells divide?
(2) What was the evolutionary advantage of type-II myosin when it emerged in the select lineage?
(3) How did the unique evolution into modern land plants happen? In the lab, we use the power of genetics, genomics, and molecular and cellular biology. Specific questions include, but not limited to:
How do the three cytoskeletal systems (actin, microtubules, and septin) contribute to cell division?
What is the involvement of extracellular matrix and the ESCRT system?
How do the known and yet-to-be known genes interact with one another to control cell division?
