Mechanical Principles Governing Pollen Tube Growth

摘要: Cellular growth and morphogenesis are central aspects of cellular differentiation. In plants, is based on the turgor driven expansion cell wall concomitant addition new material. no plant does this process occur as rapidly in pollen tube, carrier male gametes. This therefore an excellent model system to investigate processes governing dynamics growth. review provides a brief overview anatomy tube focusing structural features that implicated – cytoskeleton well spatially focused exocytotic events. The mechanics discussed various theoretical modeling approaches explain outlined. tubes from many species oscillatory or pulsatory ions signaling molecules form controlling feedback loops analyzed. A explains mechanism its mechanical components results converging available data hypotheses elaborated.
