Auxin response transcription factors(ARFs)form a large gene family,many of whose members operate at the final step of the auxin signaling pathway.ARFs participate directly in many aspects of plant growth and development.Here we summarize recent advances in understanding the roles of ARFs in regulating aspects of fleshy fruit development and ripening.ARFs play a crucial role in regulating fruit size,color,nutrients,texture,yield,and other properties that ultimately influence the ripening and quality of important crops such as tomato,apple,strawberry,and peach.ARFs impact these processes acting as positive,negative,or bidirectional regulators via phytohormone-dependent or-independent mechanisms.In the phytohormone-dependent pathway,ARFs act as a central hub linking interactions with multiple phytohormones generating diverse effects.The three domains within ARFs,namely the DNA-binding domain,the middle region,and the carboxy-terminal dimerization domain,exhibit distinct yet overlapping functions,contributing to a range of mechanisms mediated by ARFs.These findings not only provide a profound understanding of ARF functions,but also raise new questions.Further exploration can lead to a more comprehensive understanding of the regulatory mechanisms of fleshy fruit development and ripening mediated by ARFs.
