LEA — Oryza sativa Indica Group

Summary

BGIOSGA037838 (symbol LEA, preferred name OiLEA) on chromosome 12 of Indica rice encodes a protein containing the LEA_SMP domain, placing it in the late embryogenesis abundant protein family. The gene is associated with cell cycle control, calcium signaling, embryogenesis, and response to cold. It is linked to salinity tolerance, seed maturation, germination rate, photosynthetic rate, root length, and proline content. Studies of related genes in other species connect the LEA family to drought tolerance, cold tolerance, heat tolerance, grain yield, grain weight, grain size, seed dormancy, seed germination, water use efficiency, leaf chlorophyll content, and pollen fertility.
