Receptor-like kinases as surface regulators for RAC/ROP-mediated pollen tube growth and interaction with the pistil

Abstract

The research described shows the crucial roles that two RLK families play in transducing signals from growth regulatory factors to the RAC/ROP switch at the pollen tube apex to mediate and target pollen tube growth to the female gametophyte and signal its disintegration to achieve fertilization once inside the female chamber.
