ABCG5 — Triticum aestivum

Summary

TRAESCS2D02G585300, designated TaABCG5-2D on bread wheat chromosome 2D, encodes an ABCG transporter with ATP-coupled transmembrane transporter activity, ATP hydrolase activity and ATP binding. The gene is associated with Fusarium head blight resistance, a phenotype observed directly in wheat. Annotated ontology terms link TaABCG5 to hormone transport, suberin biosynthetic process, cellular osmotic and salinity responses, potassium and sodium ion homeostasis, detoxification, green leaf volatile biosynthesis, arbuscular mycorrhizae formation, and regulation of secondary shoot formation and cell cycle processes. The encoded protein localises to the membrane, plasmalemma, Casparian strip, periarbuscular membrane and suberin network. TaABCG5 is also associated with grain yield, grain number, grain weight, spike length, plant height, days to heading, waterlogging tolerance, cuticular wax content and anthocyanin pigmentation. Related genes in other species are linked to seed dormancy.
