Profilin promotes formin-mediated actin filament assembly and vesicle transport during polarity formation in pollen.

The Plant cell - 31 May 2021

Liu Chang, Zhang Yi, Ren Haiyun

Abstract excerpt

Pollen germination is critical for the reproduction of flowering plants. Formin-dependent actin polymerization plays vital roles in vesicle trafficking and polarity establishment during this process. However, how formin-mediated actin assembly is regulated in vivo remains poorly understood. Here, we investigated the function of reproductive profilin 4 and 5 (PRF4 and PRF5) in polarity establishment during pollen...
