- Dynamics and spatial organization of vesicle trafficking and secretion in
plant cell morphogenesis -*
*The University of Montreal is among the top 100 universities worldwide. A
section of the Department of biological sciences is located in the Montreal
Botanical Garden at the Plant Biology Research Institute (Institut de
recherche en biologie v=E9g=E9tale, IRBV). The Laboratory of plant cell bio=
and cytomechanics is interested in the architecture and mechanics of plant
cell structure and the dynamics of plant cell morphogenesis. We use
microscopy, micro-manipulation and mechanical modeling to understand plant
cell functioning and the mechanics of cellular growth processes.
Plant cell morphogenesis requires the targeted transport of cell wall
polymers and secreted proteins to precisly defined regions on the cell
surface. In growing pollen tubes, this involves highly efficient vesicle
trafficking to the extreme, growing end of the cell which elongates at rate=
of several micrometers per minute. In the present project, the subcellular
localization of proteins involved in the targeting of these secretory
vesicles will be studied using transformation with GFP (green fluorescent
protein). This project is financed by the Human Frontier Science Program.
