SYP72 interacts with the mechanosensitive channel MSL8 to protect pollen from hypoosmotic shock during hydration

Abstract

Pollen grains undergo desiccation and rehydration prior to germination and must survive osmotic shock. Here the authors show that the Qc-SNARE protein SYP72 is required for the localization of the mechanosensitive channel MSL8 at the plasma membrane and to maintain viability during rehydration.
