LEA — Oryza sativa Indica Group

Summary

BGIOSGA034051 (OiLEA, also known as OiRAB21, DHN1, or RAB16A) on chromosome 11 of Indica rice encodes a dehydrin family protein with a conserved dehydrin signature and lipid-binding activities, 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, calcium signaling, cell cycle control, and detoxification. It is linked to the nucleus, cytosol, and vesicle membrane. Associations from unrecorded sources connect OiLEA to 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 winter survival, cold and heat tolerance, water use efficiency, grain yield, seed size, and pollen fertility.
