AFB1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G157270 (AFB1) on durum wheat chromosome 5B encodes a protein with auxin receptor activity, auxin binding, NEDD8 transferase activity, and multiple transporter activities including auxin influx and efflux transmembrane transporter activity. It is associated with leaf rust resistance in this species. The gene is linked to auxin signalling, the SCF complex, ubiquitination and degradation of AUX/IAA proteins, and regulation of lateral root development, defense response by callose deposition, and cellular detoxification. Associations extend to traits including seed yield, biomass yield, herbicide sensitivity, root architecture, phototropism, temperature stress response, and molybdenum content. Related genes in other species link the family to auxin perception and response, grain yield, grain size, leaf blast disease response, and drought tolerance.
