The gene family participates in crucial processes including plant development, stress adaptation, and hormonal signaling cascades. While the gene family has been extensively characterized in model plant systems and agricultural crops, its functional role in , a commercially valuable tree species of significant ecological and economic importance, remains largely unexplored. In the present investigation, systematic identification and characterization of the gene family were performed in using a combination of genome-wide bioinformatics approaches and RNA-seq-based expression profiling. Nineteen genes were identified in total and further grouped into four distinct subfamilies, TIFY, JAZ (subdivided into JAZ I and JAZ II), PPD, and ZML, based on phylogenetic relationships. These genes exhibited considerable variation in gene structure, chromosomal localization, and evolutionary divergence. Promoter analysis identified a multitude of cis-acting motifs involved in mediating hormone responsiveness and regulating abiotic stress responses. Transcriptomic profiling indicated that was strongly upregulated under methyl jasmonate (JA) treatment, suggesting its involvement in JA signaling pathways. Taken together, these results offer valuable perspectives on the evolutionary traits and putative functional roles of genes.
该基因家族参与包括植物发育、胁迫适应和激素信号级联反应等关键过程。虽然该基因家族在模式植物系统和农作物中已得到广泛表征,但其在[具体树种名称](一种具有重要生态和经济价值的商业性树种)中的功能作用仍 largely 未被探索。在本研究中,利用全基因组生物信息学方法和基于 RNA-seq 的表达谱分析相结合的方式,在[具体树种名称]中对该基因家族进行了系统鉴定和表征。总共鉴定出 19 个[具体基因名称]基因,并根据系统发育关系进一步分为四个不同的亚家族,即 TIFY、JAZ(细分为 JAZ I 和 JAZ II)、PPD 和 ZML。这些基因在基因结构、染色体定位和进化分歧方面表现出相当大的差异。启动子分析鉴定出许多参与介导激素反应性和调节非生物胁迫反应的顺式作用基序。转录组分析表明,[具体树种名称]在茉莉酸甲酯(JA)处理下强烈上调,表明其参与 JA 信号通路。综上所述,这些结果为[具体树种名称]基因的进化特征和假定功能作用提供了有价值的见解。
