AUX1 — Cucumis sativus

Summary

CsAUX1 (CSA_4G308640) on cucumber chromosome 4 encodes a transmembrane transporter with auxin influx transporter activity, auxin binding, and amino acid permease activity. It is associated with auxin import into cells, response to gravity, sex differentiation, stamen development, root hair cell differentiation, and cotyledon vascular tissue pattern formation. The gene is linked to IAA content, root number and length, lateral root traits, phototropism, ethylene sensitivity, flowering time, and oxidative stress response. It is associated with gravitropism, root system architecture, lateral root formation and positioning, root hair development and polarity, phyllotaxis, and floral organ abscission. Studies of related genes in other species link the family to root gravitropism, leaf venation, lateral root development, herbicide resistance, and biomass production.
