AXR5 — Cucumis sativus

Summary

CsAXR5 (AXR5, also known as AUX22D, SHY2, IAA3, IAA4, IAA1, IAA2, IAA27, CsPAP2) on cucumber chromosome 2 encodes an AUX/IAA family protein with a PB1-like domain. The product is annotated with auxin receptor activity, auxin binding, transcription corepressor activity, and sequence-specific DNA binding, and is localized to the nucleus, cytosol, and SCF complex. CsAXR5 is associated with sex determination, inflorescence phyllotactic patterning, response to gravity, glucose-mediated signalling, and regulation of anthocyanin metabolism. It is linked to traits including biomass yield, photosynthetic ability, fruit growth and development, photoperiod-sensitive flowering time, root phototropism, phosphorus uptake, leaf angle, and water stress response. Phenotypic associations include adventitious root development, iron deficiency tolerance, seed germination, ABA sensitivity, and parthenocarpic fruit development. Studies of related genes in other species link the family to auxin resistance, lateral root initiation, and shoot regeneration.
