Plasma membrane H+-ATPases sustain pollen tube growth and fertilization

Cytosolic ion gradients in growing pollen tubes are thought to be required for polar growth. Here the authors show that the Arabidopsis plasma membrane H+ ATPases, AHA6, AHA8, and AHA9, maintain tip-to-shank proton gradients, oscillations in cytosolic pH and actin organization to enable pollen tube...
