Histone Deacetylase BpHST1 Regulates Plant Architecture and Photosynthesis in Birch.

ABSTRACT: (1) Background: Epigenetic mechanisms play a significant role in plant architecture. Histone deacetylases, as crucial epigenetic regulators, shape plant architecture by modifying chromatin structure and regulating gene expression. (2) Methods: This study combined bioinformatic identification of BpHST1 with its functional characterization in transgenic birch overexpressing 35S::BpHST1::FLAG, including phenotypic and cytological analyses. The putative direct targets of BpHST1 were further identified by integrating RNA-seq and ChIP-seq data. (3) Results: Phylogenetic analysis revealed that the HST1 orthologs from birch and peach form a distinct clade, consistent with their high degree of protein sequence conservation. BpHST1 exhibited light-inducible and lea
