ARF1 — Cucumis sativus

Summary

CsARF1 (CSA_2G068680) on cucumber chromosome 2 encodes an auxin response factor, a transcription factor with B3 DNA-binding, AUX/IAA, and PB1-like domains that binds DNA and cis-regulatory regions. It is associated with auxin signaling, response to auxin, and regulation of DNA-templated transcription. The gene has been connected to response to gravity, positive gravitropism, callus formation, floral organ and flower development, leaf development, lateral root formation, embryogenesis, and morphogenesis. It localizes to the nucleus and is linked to fruit size and seed size traits. Studies of related genes in other species associate the family with leaf color, shape, and size, plant height, stem diameter, root length, biomass yield, and chlorophyll content.
