Abstract

and auxin response transcription factor () genes are key regulators of auxin responses in plants. A total of 25 and 40 genes were identified based on the latest updated reference genome sequence. They were clustered into 10 and 8 major groups, respectively. The homologs among , soybean, and shared close relationships based on phylogenetic analysis. Gene structure analysis revealed that and genes contained one to four concern motifs and they are localized to eight chromosomes, except chromosome 6 without In addition, some and genes were expressed in all tissues, while others were specifically expressed in specific tissues. Analysis of -acting elements in promoter region and expression profiles revealed the potential response of and genes to hormones and abiotic stresses. The prediction protein-protein interaction network showed that some ARF proteins could interact with multiple Aux/IAA proteins, and the reverse is also true. The investigation provides valuable, basic information for further studies on the biological functions of and genes in the regulation of auxin-related pathways in .
