AXR5 — Cucumis sativus

Summary

CsAXR5 (CSA_7G378530) on cucumber chromosome 7 encodes an AUX/IAA family protein with auxin receptor activity, auxin binding, transcription corepressor activity, and sequence-specific DNA binding. It is associated with sex determination, inflorescence phyllotactic patterning, response to gravity, and negative regulation of transcription. The gene is linked to numerous traits including fruit position, fruit growth and development, biomass yield, photosynthetic ability, photoperiod-sensitive flowering time, leaf angle, root phototropism, and water stress response. It localizes to the nucleus, cytosol, and SCF complex. Studies of related genes in other species link the family to lateral root initiation, auxin resistance, shoot regeneration, and vascular tissue development, while related genes in potato connect it to leaf curvature and plant height.
