AFB1 — Zea mays

Summary

ZM00001EB113030 (ZmAFB1) on maize chromosome 2 encodes a protein with F-box and leucine-rich repeat domains that exhibits auxin receptor activity, auxin binding, NEDD8 transferase activity, and multiple transporter activities including auxin influx and efflux. The gene is associated with the SCF complex and nuclear localization. ZmAFB1 is associated with a wide range of biological processes including response to nitrate, regulation of defense response by callose deposition, establishment of planar polarity, and differential growth. It is linked to numerous agronomic traits including grain yield, seed yield, biomass yield, herbicide sensitivity, aluminum response, temperature stress response, phototropism, root hair length, adventitious root number, and vegetative growth time. Related genes in other species link the gene family to auxin signaling, root architecture, and inflorescence development.
