The gene family is pivotal in regulating plant growth, development, and stress responses. However, the role of in remains unclear. This study identifies 20 genes distributed across 6 chromosomes, categorized into 4 subfamilies. Analysis of their promoter sequences reveals multiple stress-related elements, including those responding to drought, low temperature, methyl jasmonate (MeJA), and gibberellin (GA). Gene expression profiling demonstrates wide expression of in callus, stem, silique, and flower tissues. Notably, expression significantly decreases under low-temperature treatment, while and show increased expression during drought stress, followed by a decrease. Protein interaction predictions suggest that homolog, , can interact with DES1, a known stress-regulating protein. Additionally, microRNA172 targeting is upregulated under cold tolerance. These findings underscore the vital role of in abiotic stress tolerance. Specifically, , and show great potential for regulating abiotic stress. This study contributes to understanding the function of and provides valuable insights for studying abiotic stress in .
基因家族在调控植物生长、发育和应激反应方面起着关键作用。然而，在 中 的作用尚不清楚。本研究鉴定了 20 个分布在 6 条染色体上的基因，分为 4 个亚家族。对它们启动子序列的分析揭示了多个与应激相关的元件，包括对干旱、低温、茉莉酸甲酯（MeJA）和赤霉素（GA）的响应。基因表达谱分析表明，在愈伤组织、茎、蒴果和花组织中广泛表达 。值得注意的是，在低温处理下， 的表达显著下降，而 和 在干旱胁迫下表达增加，随后下降。蛋白质相互作用预测表明， 同源物 可以与 DES1 相互作用，DES1 是一种已知的应激调节蛋白。此外，冷胁迫下 miR172 靶向 的表达上调。这些发现强调了 在非生物胁迫耐受性中的重要作用。具体而言， 、 和 在调节非生物胁迫方面具有很大的潜力。本研究有助于理解 的功能，并为研究 中的非生物胁迫提供了有价值的见解。
