摘要/Abstract

摘要：

PROSTRATE GROWTH1 (PROG1)是一个与水稻驯化相关的重要转录因子，在水稻株型和穗型的调控中发挥着重要作用。PROG1过度积累会使植株结构松散，无效分蘖增加，穗减小，穗粒数降低，最终导致产量下降。相反，PROG1积累不足导致昼夜节律核心调节因子OsGI下调进而从多方面影响水稻生理和发育。因此，维持水稻PROG1的稳态至关重要。在本研究中我们揭示了PROG1的负反馈调节机制，PROG1与其自身的启动子直接结合，并负调节其自身的表达，进而达到维持自身稳态的目的此外，我们的研究结果表明，PROG1的反馈调节机制独立于其互作蛋白LA1运作。这些发现为了解水稻驯化相关转录因子PROG1的调控机制提供了有价值的见解。
