TAIR Curator Summary
MSL8 encodes a protein with similarity to mechano-sensitive channel proteins. MSL8 is expressed specifically in pollen and germinating pollen tubes.It regulates pollen germination and is needed to maintain cellular integrity during pollen hydration and germination.
Mechanosensitive channel that opens in response to stretch forces in the membrane lipid bilayer. Exhibits a 6.3-fold preference for chloride over sodium. Regulates osmotic forces during pollen hydration and germination.
