AtPRK2 promotes ROP1 activation via RopGEFs in the control of polarized pollen tube growth.

Molecular plant - 1 Jul 2013

Chang Fang, Gu Ying, Ma Hong, Yang Zhenbiao

Abstract excerpt

The ROP1 GTPase-based signaling network controls tip growth in Arabidopsis pollen tubes. Our previous studies imply that ROP1 might be directly activated by RopGEF1, which belongs to a plant-specific family of Rho guanine nucleotide exchange factors (RopGEFs) and in turn may be activated by an unknown factor through releasing RopGEF1's auto-inhibition. In this study, we found that RopGEF1 forms a complex with...
