The JASMONATE-ZIM DOMAIN (JAZ) family genes are key repressors in the jasmonic acid signal transduction pathway. Recently, the JAZ gene family has been systematically characterized in many plants. However, this gene family has not been explored in the tea plant. In this study, 13 CsJAZ genes were identified in the tea plant genome. Phylogenetic analysis showed that the JAZ proteins from tea and other plants clustered into 11 sub-groups. The CsJAZ gene transcriptional regulatory network predictive and expression pattern analyses suggest that these genes play vital roles in abiotic stress responses, phytohormone crosstalk and growth and development of the tea plant. In addition, the CsJAZ gene expression profiles were associated with tea postharvest processing. Our work provides a comprehensive understanding of the CsJAZ family and will help elucidate their contributions to tea quality during tea postharvest processing.
茉莉酸-ZIM 结构域（JAZ）家族基因是茉莉酸信号转导途径中的关键阻遏子。最近，JAZ 基因家族在许多植物中得到了系统的描述。然而，该基因家族在茶树中尚未得到探索。在这项研究中，在茶树基因组中鉴定了 13 个 CsJAZ 基因。系统发育分析表明，来自茶树和其他植物的 JAZ 蛋白聚类为 11 个亚组。CsJAZ 基因转录调控网络预测和表达模式分析表明，这些基因在非生物胁迫响应、植物激素相互作用以及茶树的生长发育中发挥重要作用。此外，CsJAZ 基因的表达谱与茶叶采后加工有关。我们的工作提供了对 CsJAZ 家族的全面了解，并将有助于阐明它们在茶叶采后加工过程中对茶叶品质的贡献。
