Key messageARF4-regulated shoot regeneration through competing with ARF5 for the interaction with IAA12.AbstractPlant possess the ability to regenerate shoot meristem and subsequent the whole individual. This process is the foundation for in vitro propagation and genetic engineering and provides a system for studying fundamental biological questions, such as hormonal signaling. Auxin response factor (ARF) family transcription factors are critical components of auxin signaling pathway that regulate the transcription of target genes. To date, the mechanisms underlying the functions of class-B ARFs which act as transcription repressors remains unclear. In this study, we found that ARF4, the transcriptional repressor, was involved in regulating shoot regeneration. ARF4 interacted with auxin/Indole-3-Acetic-Acid12 (IAA12). The expression signals of ARF4 displayed a dynamic pattern similar with those of ARF5 and IAA12 during shoot meristem formation. Enhanced expression ofIAA12compromised the shoot regeneration capacity. Induced expression ofARF4complemented the regeneration phenotype ofIAA12-overexpression but did not rescued the defects in thearf5mutant,mp-S319. Further analysis revealed that ARF4 competed with ARF5 for the interaction with IAA12. The results indicate thatARF4-regulated shoot regeneration through cooperating withARF5andIAA12. Our findings provided new information for deciphering the function of class-B ARFs.
