HDA19 HY5 SIN3 LIKEs histone deacetylase complex light signaling photomorphogenesis transcriptional regulation. Our study reveals a crucial role for the HDA19 deacetylase complex in light signaling and demonstrates that the functional interplay between chromatin regulators and transcription factors regulates photomorphogenetic responses to the changing light environments. HDA19, SNL1, and HY5 associate with the same regulatory regions of HY5 and BBX22, and HY5 binding to these loci is enhanced upon SNL-HDA19 dysfunction. The HDA19 deacetylase complex is recruited by HY5 to the chromatin regions of two positive light signaling genes, HY5 and B-BOX CONTAINING PROTEIN 22 (BBX22), thereby reduces the accessibility and histone acetylation and represses their expression. We further examined the interaction between SNL-HDA19 complex and ELONGATED HYPOCOTYL5 (HY5), and their antagonistic regulation on the expressions of target genes. HDA19 and SNLs are required for histone deacetylation and chromatin inactivation of PHYA gene. Light-repression of HDA19 and SNLs expression is mediated by photoreceptors. Here, we identify the conserved SWI-INDEPENDENT3 LIKE (SNL)-HISTONE DEACETYLASE19 (HDA19) deacetylase complex, including HDA19 and SNL1-SNL6, as a negative regulator of the light signaling pathway. However, the chromatin-based regulation of this process remains to be elucidated. Reprogramming of the transcriptome during photomorphogenesis requires dynamic changes in chromatin and distribution of histone modifications. ![]()
