Late embryogenesis abundant protein (LEA) genes are widely conserved in seed plant species and form a multigene family. While some LEAs are known to respond to environmental stresses, the function of many LEAs is unknown. OsLEA5 (Lea14A) interacts with a regulator of the endosperm storage production, FLO2, suggesting that OsLEA5 may be involved in endosperm quality control. RNAi knockdown line of OsLEA5 showed decreased seed weight. Transformant lines overexpressing OsLEA5 exhibited improved quality and seed weight of mature seeds when they were developed under high-temperature conditions, while seed quality strongly declined in wild-type plants exposed to high-temperature stress. These findings indicate that OsLEA5 contributes to suppressing the deterioration of seed quality when developed under high-temperature conditions.
