Pollen tube growth requires a Ca gradient, with elevated levels of cytosolic Ca at the growing tip. This gradient’s magnitude oscillates with growth oscillation but is always maintained. Ca influx into the growing tip is necessary, and its magnitude also oscillates with growth. It has been widely assumed that stretch-activated Ca channels underlie this influx, but such channels have never been reported in either pollen grains or pollen tubes. We have identified and characterized stretch… CONTINUE READING
