Plant Physiology

I am interested in the physiological mechanisms that allow for tip growth in highly polarized plant cells. Specifically, I focus on lily pollen tubes and to a lesser extend the moss Physcomitrella patens. These two systems allow for examination of the interplay between energy metabolism, cytoskeletal dynamics and vesicle trafficking. Recently I have been examining the role of a prominent actin structure at the pollen tube tip to determine whether it maintains polarized cell wall deposition.
