ATDI8 — Brassica oleracea var. botrytis

Summary

BoATDI8, also known as RAB18, is a cauliflower gene on chromosome 9 that encodes a dehydrin family protein. The product possesses lipid, phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding activities. 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, gibberellin biosynthesis, and ABA signaling. 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 this family to traits including drought tolerance, water use efficiency, transpiration rate, stomatal resistance and opening, germination rate, root length, seed maturation, and abscisic acid and calcium content.
