AXR5 — Cucumis sativus

Summary

CSA_5G166440, also known as AXR5, IAA1, or CsAUX22D on cucumber chromosome 5, encodes an AUX/IAA family protein with domains including AUX_IAA and PB1-like. The product exhibits auxin receptor activity, auxin binding, transcription corepressor activity, and sequence-specific DNA binding, among other molecular functions. This gene is associated with sex determination, inflorescence phyllotactic patterning, response to gravity, and negative regulation of transcription by RNA polymerase II. It localizes to the nucleus, cytosol, and SCF complex. Associations include traits such as biomass yield, photosynthetic ability, fruit growth and development, photoperiod-sensitive flowering time, root phototropism, and responses to water stress, nitrate, and glyphosate. Related genes in other species are linked to auxin resistance, lateral root initiation, and shoot regeneration.
