| Summary: | Histone deacetylases (HDACs), known as histone acetylation erasers, function crucially in plant growth and development. Although there are abundant reports focusing on <i>HDACs</i> of Arabidopsis and illustrating their important roles, the knowledge of <i>HDAC</i> genes in Tartary buckwheat (Polygonales Polygonaceae <i>Fagopyrum tataricum</i> (L.) Gaertn) is still scarce. In the study, a total of 14 <i>HDAC</i> genes were identified and divided into three main groups: Reduced Potassium Dependency-3/His-52 tone Deacetylase 1 (RPD3/HDA1), Silent Information Regulator 2 (SIR2), and the plant-53 specific HD2. Domain and motif composition analysis showed there were conserved domains and motifs in members from the same subfamilies. The 14 <i>FtHDACs</i> were distributed asymmetrically on 7 chromosomes, with three segmental events and one tandem duplication event identified. The prediction of the <i>cis</i>-element in promoters suggested that <i>FtHDACs</i> probably acted in numerous biological processes including plant growth, development, and response to environmental signals. Furthermore, expression analysis based on RNA-seq data displayed that all <i>FtHDAC</i> genes were universally and distinctly expressed in diverse tissues and fruit development stages. In addition, we found divergent alterations in <i>FtHDACs</i> transcript abundance in response to different light conditions according to RNA-seq and RT-qPCR data, indicating that five <i>FtHDACs</i> might be involved in light response. Our findings could provide fundamental information for the HDAC gene family and supply several targets for future function analysis of <i>FtHDACs</i> related with light response of Tartary buckwheat. |
