摘要
Key message The most recent outcomes about the transcription factors and transcription complexes mediated auxin signaling pathway by the histone acetylation and deacetylation. Abstract The phytohormone auxin, is required to regulate its accumulation spatiotemporally and responses to orchestrate various developmental levels in plants. Histone acetylation and deacetylation modulate auxin biosynthesis, its distribution and accumulation. In the absence of auxin, histone deacetylase represses the expression of auxin-responsive genes. Various transcription factors and transcription complexes facilitate the proper regulation of auxin signaling pathway genes. The primary and lateral root development, promotion of flowering and initiation of seed germination are all regulated by auxin-mediated histone acetylation and deacetylation. These findings conclude the auxin mode of action, which is mediated by histone acetylation and deacetylation, and associated phenotypic responses in plants, along with the underlying mechanism of these modifications.
