Description
Summary: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 <i>ZF-HD</i> gene family was performed in wheat. A total of 37 <i>TaZF-HD</i> genes were identified in <i>T. aestivum</i> and classified into six groups. The results of a synteny analysis showed that gene replication events contributed to the expansion of the <i>TaZF-HD</i> gene family. The <i>TaZF-HD</i> paralogous gene pairs with similar chromosomal locations in different subgenomes had similar expression patterns. <i>TaZF-HD</i>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 <i>ZF-HD</i> genes and provide robust candidate genes for future functional investigations aimed at crop improvement.
