AFB1 — Triticum turgidum subsp. durum

Summary

TRITD2BV1G142790 (AFB1) on durum wheat chromosome 2B encodes a protein with F-box and leucine-rich repeat domains, exhibiting auxin receptor activity, auxin binding, NEDD8 transferase activity, and multiple transporter activities including auxin influx and efflux. The gene is associated with leaf rust resistance in this species, and with aflatoxin biosynthesis, SCF complex assembly, regulation of defense response by callose deposition, response to oomycetes, cellular response to nitrate, and regulation of lateral root development. It localizes to the nuclear SCF complex and ubiquitin ligase complex. Associations include seedling cotyledon size, molybdenum content, adventitious root number, seed yield, biomass yield, herbicide sensitivity, phototropism, and temperature stress response. Related genes in other species link the gene to auxin signaling, leaf flattening, herbicide resistance, and biomass production.
