摘　　要：The auxin response factor(ARF)and auxin/indole-3-acetic acid(Aux/IAA)family of genes are central components of the auxin signaling pathway and play essential roles in plant growth and development.Their large-scale analysis and evolutionary trajectory of origin are currently not known.Here,we identified the corresponding ARF and Aux/IAA family members and performed a large-scale analysis by scanning 406 plant genomes.The results showed that the ARF and Aux/IAA gene families originated from charophytes.The ARF family sequences were more conserved than the Aux/IAA family sequences.Dispersed duplications were the common expansion mode of ARF and Aux/IAA families in bryophytes,ferns,and gymnosperms;however,whole-genome duplication was the common expansion mode of the ARF and Aux/IAA families in basal angiosperms,magnoliids,monocots,and dicots.Expression and regulatory network analyses revealed that the Arabidopsis thaliana ARF and Aux/IAA families responded to multiple hormone,biotic,and abiotic stresses.The APETALA2 and serum response factor-transcription factor gene families were commonly enriched in the upstream and downstream genes of the ARF and Aux/IAA gene families.Our study provides a comprehensive overview of the evolutionary trajectories,structural functions,expansion mechanisms,expression patterns,and regulatory networks of these two gene families.
