ATDI8 — Brassica oleracea var. botrytis

Summary

BoATDI8 (also known as ATDI8, RAB18, or BoRAB18) on cauliflower chromosome 2 encodes a dehydrin family protein, characterized by a dehydrin conserved sequence and possessing lipid-binding activity, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding. In cauliflower, this gene is associated with responses to abscisic acid, salt, desiccation, wounding, and 1-aminocyclopropane-1-carboxylic acid, as well as with cold acclimation, stomatal closure, seed germination, and gibberellin biosynthesis. It is linked to drought stress response and seed dormancy. The protein localizes to the vesicle membrane and cytosol. Studies of related genes in other species connect the family to traits such as drought tolerance, water use efficiency, transpiration rate, stomatal resistance, germination rate, root length, and abscisic acid content.
