摘要:

高温热害是影响水稻(Oryza sativa)产量形成的重要限制因子。DEAD-box RNA解旋酶在核糖体RNA前体加工及植物抗逆中扮演着重要角色。最近, 中国科学家在DEAD-box RNA解旋酶调控水稻耐热性分子机理研究方面取得了突破性进展。

关键词: DEAD-box RNA解旋酶, 内稳态, 核糖体RNA (rRNA), 水稻, 耐热性

Abstract:

High temperature stress is a significant factor limiting rice growth and yield formation. DEAD-box RNA helicase plays a vital role in the processing of pre-rRNA and plant stresses response. Recently, Chinese scientists have great progress in the molecular mechanism of regulating thermo-tolerant of DEAD-box RNA helicase in rice.

Key words: DEAD-box RNA helicase, homeostasis, ribosomal RNA (rRNA), rice, thermotolerance
