ABCB25 (TRAESCS2D02G523100) — triticum aestivum

Summary

TRAESCS2D02G523100 (symbol ABCB25, preferred name TaMDR1) on bread wheat chromosome 2D encodes a protein with Type_1_exporter, ABC1_TM_dom, ABC1_TM_sf, ABC_transporter-like_CS, ABC_transporter-like_ATP-bd, AAA+_ATPase, and P-loop_NTPase domains, annotated with ATP-coupled transmembrane transporter activity, ATP hydrolase activity, and multiple substrate-specific transporter activities including aluminium ion, auxin efflux, sulfate, thiosulphate, UDP-glucose, and phosphate transmembrane transport. The gene is associated with aluminium toxicity response and detoxification, auxin polar transport, activation of brassinosteroid-mediated signalling, photomorphogenesis, positive gravitropism, cell size control, stamen development, anthocyanin accumulation in response to UV light, response to desiccation, and mucilage extrusion from seed coat. It is linked to the tonoplast, plasmalemma, vesicle membrane, and ABC transporter complex. Studies of related genes in other species connect the family to aluminium tolerance and cell wall biosynthesis.
