RCN1 — Triticum aestivum

Summary

TRAESCS5B02G087400, also known as RCN1, TaABCG2, or TaABCG10-5B, encodes an ABC transporter of the ABCG family with ATP-coupled transmembrane transporter activity and ATP hydrolase activity. In bread wheat (Triticum aestivum) on chromosome 5B, this gene is associated with Fusarium head blight resistance. It is linked to suberin biosynthetic processes, Casparian strip and membrane localization, and responses to salt, osmotic stress, hypoxia, and hormones including gibberellin, jasmonic acid, auxin, and salicylate. The gene is also associated with potassium and sodium ion homeostasis, regulation of secondary shoot formation, green leaf volatile biosynthesis, detoxification, and arbuscular mycorrhizae formation. Related genes in other species are linked to grain number, grain weight, plant height, spike length, and root and shoot biomass traits.
