LEA — Oryza sativa Indica Group

Summary

BGIOSGA034053, also known as LEA or OiLEA, encodes a dehydrin family protein on chromosome 11 of Indica rice, characterized by a dehydrin conserved sequence and annotated with lipid, phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding activities. The gene is associated with seed maturation, embryogenesis, cold acclimation, response to abscisic acid, cell cycle control, calcium signaling, 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 salt stress, while RAB21 is associated with water stress response. The gene is further 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, water use efficiency, and seed germination.
