JAZ is a plant-specific protein family involved in the regulation of plant development, abiotic stresses, and responses to phytohormone treatments. In this study, we carried out a bioinformatics analysis of JAZ genes in turnip by determining the phylogenetic relationship, chromosomal location, gene structure and expression profiles analysis under stresses. The 36 JAZ genes were identified and classified into four subfamilies (ZML, JAZ, PPD and TIFY). The JAZ genes were located on 10 chromosomes. Two gene pairs were involved in tandem duplication events. We identified 44 collinear JAZ gene pairs in the turnip genome. Analysis of the Ka/Ks ratios indicated that the paralogs of the BrrJAZ family principally underwent purifying selection. Expression analysis suggested JAZ genes may be involved in the formation of turnip tuberous root, and they also participated in the response to ABA, SA, MeJA, salt stress and low-temperature stress. The results of this study provided valuable information for further exploration of the JAZ gene family in turnip.
JAZ 是一个植物特有的蛋白家族，参与植物发育、非生物胁迫和对植物激素处理的响应的调控。在这项研究中，我们通过确定拟南芥 JAZ 基因的系统发育关系、染色体定位、基因结构和胁迫下的表达谱分析，对芜菁 JAZ 基因进行了生物信息学分析。鉴定了 36 个 JAZ 基因，并将其分为四个亚家族（ZML、JAZ、PPD 和 TIFY）。JAZ 基因位于 10 条染色体上。有两个基因对涉及串联重复事件。在芜菁基因组中鉴定出 44 对共线性 JAZ 基因对。Ka/Ks 比值分析表明，BrrJAZ 家族的旁系同源基因主要经历了纯化选择。表达分析表明，JAZ 基因可能参与芜菁块根的形成，它们还参与了对 ABA、SA、MeJA、盐胁迫和低温胁迫的响应。本研究的结果为进一步探索芜菁 JAZ 基因家族提供了有价值的信息。
