LDS1 — Brassica oleracea var. botrytis

Summary

BoLDS1 (BOLND125_C05P039280.1_BOLND125_V1) on cauliflower chromosome 5 encodes a small GTPase of the Rab family with GTPase activity and GTP binding. The gene is associated with gibberellin biosynthesis, stomatal closure, cold acclimation, intracellular protein transport, vesicle transport, seed germination, and ABA signaling. Its product localises to the endomembrane system, stress granules, Golgi membrane, ER membrane, Golgi complex, plasmalemma, and nucleus. BoLDS1 is linked to seed dormancy, dehydration and freezing stress tolerance, drought tolerance, lipid droplet dynamics, autophagy, stomatal development, and ABA responsiveness. Related genes in other species connect the family to abscisic acid response, drought and salt stress tolerance, phosphate deficiency response, and traits including water use efficiency, transpiration rate, root length, plant height, and seed longevity.
