摘要 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)转录因子家族中的一个亚家族成员,其通过调控基因的表达,在抑制种子发芽,提高幼苗暗形态发生,促进避荫反应等方面起作用。本综述通过对PIFs转录因子的生物学功能研究进展的总结,为PIFs的进一步研究提供帮助。 PIFs (phytochrome-interacting factors) are members of a small subset of basic helix-loop-helix transcription factors. By reg·Lating the expression of downstream genes, PIFs play a vital role in many biological processes, such as repressing seed germination, promoting seedling skotomorphogenesis and promoting shade-avoidance. This review summarizes the research progress of biological function of PIFs, and provides help for the further study of PIFs.
