赤霉素信号在非生物胁迫中的作用及其调控机制研究进展

Research Progress on the Role and Regulation Mechanism of Gibberellin Signal in Response to Abiotic Stress

赤霉素(GA)能促进种子萌发和植物生长发育。近年来的研究表明赤霉素这一激素在植物响应非生物胁迫中同样发挥着重要的作用。植物通过调节GA生物合成、信号转导及其生物活性提高胁迫耐受性。综述了赤霉素在应对常见的几类非生物胁迫中所起的作用,分析了其合成、信号转导通路调控机制以及赤霉素与其他激素在响应非生物胁迫的关系。

Gibberellin（GA）could promote seed germination and plant growth. Recent studies show that gibberellin plays an equally important role in the response of plant to abiotic stress. Plants increase stress tolerance by regulating GA biosynthesis, signal transduction and biological activity. In this paper we review the role of GA in response to common types of abiotic stress. The mechanisms of the synthesis, signal transduction and regulation of GA as well as the relationship with other hormones in response to abiotic stress are analyzed.
