ABCG3 — Triticum aestivum

Summary

TRAESCS5D02G551400, designated TaABCG3 on wheat chromosome 5D, encodes an ABC transporter with ATP-coupled transmembrane transporter activity and ATP hydrolase activity, belonging to the Plant_ABCG family. In bread wheat, TaABCG3 is associated with Fusarium head blight resistance, suberin biosynthetic process, cellular osmotic and salinity responses, potassium and sodium ion homeostasis, green leaf volatile biosynthetic process, arbuscular mycorrhizae formation, and regulation of secondary shoot formation and cell cycle processes. The gene product localizes to the suberin network, Casparian strip, periarbuscular membrane, and plasmalemma. TaABCG3 is also linked to panicle length, grain yield per plant, grains per spike, seed size, shoot fresh weight, auxin content, floral organ identity, heterosis, and protein content. Studies of related genes in other species connect the family to photochemical quenching and fusarium head blight response.
