AXR5 — Cucumis sativus

Summary

CsAXR5 (CSA_3G143580) on cucumber chromosome 3 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 regulation of anthocyanin anabolism. The gene is linked to numerous traits including biomass yield, photosynthetic ability, fruit growth and development, photoperiod-sensitive flowering time, root phototropism, leaf angle, and water stress response. It localizes to the nucleus, cytosol, plasmalemma, and SCF complex. Related genes in other species are linked to lateral root initiation, shoot regeneration, auxin and abscisic acid resistance, parthenocarpy, and responses to low light intensity and fungal pathogens.
