ABCG4 — Triticum aestivum

Summary

TaABCG4 (TRAESCS7A02G342000) on chromosome 7A encodes an ABC transporter with ATP-coupled transmembrane transporter activity, ATP hydrolase activity, and ATP binding, belonging to the ABCG transporter family. In bread wheat, it is associated with Fusarium head blight resistance, hormone transport, suberin biosynthetic process, cellular osmotic and salinity responses, potassium and sodium ion homeostasis, regulation of secondary shoot formation, meristem initiation and size, anthocyanin accumulation in response to UV light, green leaf volatile biosynthesis, cell tip growth, detoxification, and determination of bilateral symmetry. It localizes to the suberin network, Casparian strip, periarbuscular membrane, mitochondria, and plasmalemma. Studies of related ABCG family members in other species link the family to salt, heat, osmotic, and cold tolerance, as well as fusarium head blight response.
