The Rab GTPase RabA4d regulates pollen tube tip growth in Arabidopsis thaliana.

The Plant cell - 1 Feb 2009

Szumlanski Amy L, Nielsen Erik

Abstract excerpt

During reproduction in flowering plants, pollen grains form a tube that grows in a polarized fashion through the female tissues to eventually fertilize the egg cell. These highly polarized pollen tubes have a rapid rate of growth that is supported by a tip-focused delivery of membrane and cell wall components. To gain a better understanding of how this growth is regulated, we investigated the function RABA4D, a...
