LDS1 — Brassica oleracea var. botrytis

Summary

BoLDS1 (LDS1, also known as BoRAB18, BoRABC1, BoATRABC1, and BoATRAB18) on cauliflower chromosome 6 encodes a small GTPase of the Rab family, possessing GTPase activity and GTP binding. This gene is associated with gibberellin biosynthesis, stomatal closure, cold acclimation, intracellular protein transport, vesicle transport, protein transport, seed germination, and ABA signaling. Its product localizes to the endomembrane system, stress granules, Golgi membrane, ER membrane, ER, Golgi complex, plasmalemma, and nucleus. BoLDS1 is linked to seed dormancy, dehydration stress tolerance, freezing stress tolerance, drought tolerance, stress response, water stress response, lipid droplet dynamics, autophagy, stomatal development, ABA response, and abscisic acid responsiveness. Related genes in other species are linked to abscisic acid content, phosphorus response, water stress response, seed longevity, transpiration rate, water use efficiency, root length, plant height, low temperature stress response, stomatal opening, and salt tolerance.
