摘　　要：植物光敏色素作用因子(phytochrome interacting factors, PIFs)属于碱性–螺旋–环–螺旋(basic helix-loop-helix, bHLH)转录因子家族,在植物生长发育中起到"枢纽"作用,参与调控光形态建成、暗形态建成、非生物胁迫、生物钟、开花、种子萌发、避荫反应等过程。该文主要介绍PIFs转录因子参与调控植物生长发育最新研究进展,并对PIFs转录因子的研究现状进行总结与展望,为进一步探讨PIFs转录因子的功能及机制提供参考。The plant phytochrome interacting factors(PIFs) belong to the family of basic helix-loop-helix(bHLH) transcription factors, which play a "hub" role in plant growth and development. PIFs are involved in the regulation of photomorphogenesis, skotomorphogenesis, abiotic stress, circadian clock, flowering, seed germination, and shade avoidance syndrome. This review mainly introduces the latest research progress of PIFs transcription factors involved in the regulation of plant growth and development. This review summarizes and prospects the research status of PIFs transcription factors, which provides a reference for further exploring the function and mechanism of PIFs transcription factors.
