ZF-HD基因家族在植物的发育过程和逆境应答中起着重要作用。然而，ZF-HD基因在大白菜中的功能仍不清楚。大白菜（Brassica rapassp.）pekinensis）是世界范围内种植的最重要的叶菜之一。大白菜全基因组序列已确定，迄今已鉴定出4万多个蛋白质。本研究在大白菜中鉴定了31个ZF-HD基因。BraZF-HD基因可分为ZHD和MIF两个亚家族。其中，ZHD基因是植物特异性的，几乎所有的内含子，并与仅具有锌指的MINI ZINC FINGER基因相关。系统发育分析表明，ZHDs在被子植物进化过程中得到了相当大的扩展。此外，ZHD组有24个成员，是拟南芥ZHD组的2倍，表明大白菜ZHD基因比其他组基因更频繁地被保留。Real-time PCR分析表明，BraZF-HD基因主要在花中表达。此外，这些基因中的大多数在光周期或春化条件以及非生物胁迫下被显着诱导。从而暗示它们可能在这些过程中发挥重要作用。本研究为深入了解ZF-HD基因在大白菜基因组中的进化提供了依据，并为进一步研究ZF-HD基因在开花和抗性中的功能奠定了基础。
The ZF-HD gene family plays an important role in plant developmental processes and stress responses. However, the function of the ZF-HD genes in Chinese cabbage remains largely unknown. Chinese cabbage (Brassica rapassp. pekinensis) is a member of one of the most important leaf vegetables grown worldwide. The entire Chinese cabbage genome sequence has been determined, and more than forty thousand proteins have been identified to date. In this study, 31 ZF-HD genes were identified in Chinese cabbage. We show here that theBraZF-HDgenes could be categorized into ZHD and MIF subfamilies. Among them, ZHD genes are plant-specific, nearly all intronless, and related to MINI ZINC FINGER genes that possess only the zinc finger. Phylogenetic analysis suggested that ZHDs have expanded considerably during angiosperm evolution. In addition, the ZHD group has 24 members, which is twice as much as theArabidopsisZHD group, indicating that the Chinese cabbage ZHD genes have been retained more frequently than other group genes. Real-time PCR analysis showed that most ofBraZF-HDgenes are preferentially expressed in flower. Furthermore, most of these genes are significantly induced under photoperiod or vernalization conditions, as well as abiotic stresses. Thereby implying that they may play important roles in these processes. This study provides insight into the evolution of ZF-HD genes in Chinese cabbage genome and may aid efforts to further characterize the function of these predicted ZF-HD genes in flowering and resistance.
