LEA — Oryza sativa Indica Group

Summary

BGIOSGA034054, designated OiLEA and also known as OiRAB21 and DHN1, encodes a dehydrin family protein on chromosome 11 of Indica rice. The product contains a dehydrin conserved sequence and exhibits lipid binding, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding. In this species, the gene is associated with salt tolerance, water stress response, seed maturation, embryogenesis, cold acclimation, response to abscisic acid, cell cycle control, calcium signaling, and detoxification. It localizes to the vesicle membrane, cytosol, and nucleus. Associations with salinity tolerance, proline content, germination rate, photosynthetic rate, root length, seedling establishment, and desiccation tolerance have been reported. Studies of related genes in other species link the family to drought tolerance, cold tolerance, grain yield, seed germination, and winter survival.
