摘要： The ARF gene family plays important roles in intracellular transport in eukaryotes and is involved in conferring tolerance to biotic and abiotic stresses in plants. To explore the role of these genes in the development of wheat (Triticum aestivum L.), 74 wheat ARF genes (TaARFs; including 18 alternate transcripts) were identified and clustered into seven sub-groups. Phylogenetic analysis revealed that TaARFA1 subgroup genes were strongly conserved. Numerous cis-elements functionally associated with the stress response and hormones were identified in the TaARFA1 sub-group, implying that these TaARFs are induced in response to abiotic and biotic stresses in wheat. According to available transcriptome data and qRT-PCR analysis, the TaARFA1 genes displayed tissue-specific expression patterns and were regulated by biotic stress (powdery mildew and stripe rust) and abiotic stress (cold, heat, ABA, drought and NaCl). Protein interaction network analysis further indicated that TaARFA1 proteins may interact with protein phosphatase 2C (PP2C), which is a key protein in the ABA signaling pathway. This comprehensive analysis will be useful for further functional characterization of TaARF genes and the development of high-quality wheat varieties.
