MRP4 — triticum aestivum

Summary

TRAESCS7B02G052900, also known as TaABCC13 or MRP4, encodes an ABC transporter C family member 13 on bread wheat chromosome 7B. The product exhibits ABC-type xenobiotic, aluminium ion, thiosulphate, sulfate, UDP-glucose, and phosphate transmembrane transporter activities, along with ATP binding and hydrolase activity. This gene is associated with aluminium ion transmembrane transport and detoxification, response to aluminium, UDP-glucose and phosphate ion membrane transport, detoxification, and regulation of cell cycle processes. It is linked to grain quality, lateral root number, and seed growth and development traits, with silencing studies connecting it to lateral root formation, seed germination, and grain development. The protein localises to the tonoplast, vesicle membrane, plasmalemma, and ABC transporter complex. Studies of related genes in other species link the family to similar transport functions.
