Rab11 GTPase-regulated membrane trafficking is crucial for tip-focused pollen tube growth in tobacco.

The Plant cell - 1 Sept 2005

Abstract excerpt

Pollen tube growth is a polarized growth process whereby the tip-growing tubes elongate within the female reproductive tissues to deliver sperm cells to the ovules for fertilization. Efficient and regulated membrane trafficking activity incorporates membrane and deposits cell wall molecules at the tube apex and is believed to underlie rapid and focused growth at the pollen tube tip. Rab GTPases, key regulators of...
