AFB1 — Zea mays

Summary

ZM00001EB085030, designated ZmAFB1 on maize chromosome 2, encodes a protein with F-box and leucine-rich repeat domains, and is associated with auxin receptor activity, NEDD8 transferase activity, auxin binding, and is a component of the SCF ubiquitin ligase complex. The gene is associated with auxin signalling, seed development, reproductive meristem phase change, and regulation of seed size. It has been linked to numerous agronomic traits including grain yield per plant, biomass yield, seed yield, vegetative growth time, root hair length, adventitious root number, phototropism, herbicide sensitivity, and temperature stress response. Studies of related genes in other species connect this gene family to auxin perception, lateral root formation, inflorescence architecture, and leaf flattening, as well as to leaf blast disease response, grain size, and drought tolerance.
