ARF6 — Cucumis sativus

Summary

CsARF6 (CSA_1G536820) on cucumber chromosome 1 encodes an auxin response factor (ARF) family protein containing B3 DNA-binding, AUX/IAA, and PB1-like domains, with DNA-binding transcription factor activity and the ability to bind chromatin, cis-regulatory regions, and other proteins. The gene is associated with auxin signalling, ARF inactivation by AUX/IAA, and regulation of auxin biosynthesis, as well as vasculature development, leaf and lateral root morphogenesis, shoot regeneration, thermomorphogenesis, and leaf senescence. It has been linked to fruit set, fruit quality, total soluble sugar content, carpel morphology, leaf area, plant nutrient response, peduncle length, adventitious root number, heterosis, temperature stress response, male sterility, and phosphorus uptake. Studies of related genes in other species connect the family to drought tolerance, thermomorphogenesis, flowering time, phototropism, and root meristem growth.
