LAX3 — Arabidopsis thaliana

Summary

AT1G77690 (LAX3) on chromosome 1 of Arabidopsis thaliana encodes a protein with an AA_transpt_TM domain and is annotated for auxin influx transmembrane transporter activity, symporter activity, auxin binding, auxin receptor activity, and amino acid permease activity. LAX3 is associated with auxin import into cells, auxin anabolism and breakdown, phyllotactic patterning, vasculature development, regulation of lateral root development, root hair cell differentiation, shade avoidance, stamen development, and dehiscence. It is linked to traits including IAA content, root branching, adventitious root number, phototropism response trait, herbicide sensitivity, seed yield, ethylene sensitivity, leaf morphology trait, flowering time trait, and oxidative stress response. Localisation evidence links LAX3 to the plasma membrane, endosome, Golgi complex, and SCF ubiquitin ligase complex. Studies of related genes in other species connect LAX3 to auxin uptake, gravitropism, root architecture, and stress responses.
