Zinc finger-homeodomain transcriptional factors (ZF-HDs), a kind of plant-specific transcription factor, play important roles in plant growth, development and various stress responses. In this study, the genome-wide analysis of the gene family was performed in wheat. A total of 37 genes were identified in and classified into six groups. The results of a synteny analysis showed that gene replication events contributed to the expansion of the gene family. The paralogous gene pairs with similar chromosomal locations in different subgenomes had similar expression patterns. s were highly induced under PEG (polyethylene glycol), NaCl and cold stress but not induced under heat stress. Gene ontology (GO) annotation and protein-protein interactions suggested that TaZF-HD proteins may participate in various biological processes of plants. These results increase our understanding of genes and provide robust candidate genes for future functional investigations aimed at crop improvement.
锌指-同源异型域转录因子（ZF-HDs）是一类植物特有的转录因子，在植物生长、发育及各种胁迫响应中发挥重要作用。本研究对小麦中的该基因家族进行了全基因组分析。共鉴定出37个基因，并将其分为六组。共线性分析结果表明，基因复制事件促进了该基因家族的扩张。不同亚基因组中具有相似染色体位置的旁系同源基因对具有相似的表达模式。这些基因在聚乙二醇（PEG）、氯化钠和冷胁迫下高度诱导表达，但在热胁迫下不诱导表达。基因本体（GO）注释和蛋白质-蛋白质相互作用表明，TaZF-HD蛋白可能参与植物的各种生物学过程。这些结果增进了我们对该基因的理解，并为未来旨在作物改良的功能研究提供了有力的候选基因。
