LEA — Oryza sativa Indica Group

Summary

BGIOSGA034050 (OiLEA, also known as OiRAB21, DHN1, or RAB16A) on chromosome 11 of Indica rice encodes a dehydrin family protein with lipid-binding activity, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding. This gene is associated with seed maturation, embryogenesis, cold acclimation, response to abscisic acid, calcium signaling, cell cycle control, detoxification, and signal transduction. It localizes to the vesicle membrane, cytosol, and nucleus. In this species, the RAB16A variant is linked to salt tolerance and water stress response. The gene is also associated with salinity tolerance, proline content, germination rate, photosynthetic rate, root length, seedling establishment, drought, desiccation tolerance, and ABA response. Studies of related genes in other species link the family to traits including grain yield, cold tolerance, heat tolerance, water use efficiency, seed size, and winter survival.
