“…In the Aux/IAA family clade A and clade B were enriched in many of the same families, such as the AP2, WRKY, SRF-TF, and TCP gene families. The AP2 family is mainly associated with plant disease resistance (Zhu et al 2021 ), the WRKY family is associated with the immune response (Saha et al 2024 ), the SRF-TF family is associated with flower development (Ning et al 2023 ), and the TCP family is associated with cell differentiation and growth (Viola and Gonzalez 2023 ). Therefore, the Aux/IAA gene family may mediate plant growth and various stresses through mutual regulation with these gene families.…”

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.
