Abstract

Histone deacetylases (HDACs), widely found in various types of eukaryotic cells, play crucial roles in biological process, including the biotic and abiotic stress responses in plants. However, no research on the HDACs of has been reported. Here, 14 putative genes were identified and annotated in . Their gene structure, motif composition, -acting elements, phylogenetic relationships, protein structure, alternative splicing events, subcellular localization and gene expression pattern were investigated. The gene structure showed were classified into three subfamilies. The promoter analysis revealed the presence of various -acting elements responsible for hormone, abiotic stress and developmental regulation for the specific induction of Two duplication events were identified in , , and . The expression patterns of showed their correlation with the flavonoid synthesis pathway genes. In addition, alternative splicing, mRNA enrichment profiles and transgenic analysis showed the potential role of in cold responses. Our study characterized s, providing a candidate gene family for agricultural breeding and crop improvement.

摘要

组蛋白去乙酰化酶（HDACs）广泛存在于各种真核细胞中，在生物过程中发挥着关键作用，包括植物的生物和非生物胁迫反应。然而，目前尚未有关于 物种的 HDACs 的研究报道。在这里，我们在 中鉴定并注释了 14 个推定的 基因。我们研究了它们的基因结构、基序组成、顺式作用元件、系统发育关系、蛋白质结构、可变剪接事件、亚细胞定位和基因表达模式。基因结构表明 被分为三个亚家族。启动子分析表明存在各种顺式作用元件，负责激素、非生物胁迫和发育调控，以特异性诱导 两个基因在 中发生了复制事件，分别是 和 。 的表达模式表明它们与类黄酮合成途径基因相关。此外，可变剪接、mRNA 丰度谱和转基因分析表明 在冷响应中的潜在作用。我们的研究对 进行了特征描述，为农业育种和作物改良提供了候选基因家族。
