摘　要：

光敏色素作用因子(PIFs)属于bHLH 转录因子家族, 在植物的生长发育中起到重要调节作用。作为一个关键的胞内信号调控组分, PIFs 扮演着整合不同激素信号通路“枢纽”的角色。现有研究表明, PIFs能影响GA、ABA、IAA等激素的合成, 调控GA、BR、JA、IAA、ABA、乙烯等激素的信号传递。本文重点阐述PIFs在植物激素信号中调控功能的研究进展, 以期为进一步探索PIFs的功能及机制提供帮助。

Abstract:

Phytochrome interacting factors (PIFs) belonging to basic helix-loop-helix (bHLH) transcription factors family, play an important role in plant growth and development. As the hubs of signal network in plant, PIFs integrate multiple plant hormone signals to regulate the transcriptional network. Existing research shows that PIFs can not only affect the synthesis of GA, ABA and IAA, but also regulate signal transmission of GA, BR, JA, IAA, ABA and ethylene. This review summarizes the research progress of function of PIFs in plant homone, and provides help for the further study of PIFs.
