AUX1 — Cucumis sativus

Summary

CsAUX1 (CSA_5G374730) on cucumber chromosome 5 encodes a protein with an AA_transpt_TM domain and is associated with auxin influx transmembrane transporter activity, auxin receptor activity, auxin binding, IP6 binding, amino acid permease activity, symporter activity, ubiquitin-protein transferase activity, and protein binding. It is associated with auxin import into cell, auxin polar transport, response to gravity, positive gravitropism, root hair cell differentiation, root cap development, lateral root formation, stamen development, sex determination, mating, somatic embryogenesis, cotyledon vascular tissue pattern formation, response to nematode, cellular response to phosphate starvation, and graft union formation. The gene is linked to IAA content, rootless, adventitious rootless, root number, root length, root thickness, phototropism response trait, herbicide sensitivity, ethylene sensitivity, leaf morphology trait, leaf vein morphology trait, flowering time trait, and SALTTL. Studies of related genes in other species connect the AUX/LAX family to root gravitropism, lateral root emergence, leaf venation, herbicide resistance, biomass production, and seed yield.
