ANT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0525300, designated HvANT1 on barley chromosome 5H, encodes an amino acid permease with aromatic amino acid and neutral amino acid transmembrane transporter activity, localised to the vacuolar and ER membranes. The gene is associated with grain pericarp colour, pigmentation, and the biosynthesis of melanin, anthocyanins, phenylpropanoids and flavonoids. It has been linked to flavonoid and anthocyanin content, amino acid transport, grain yield and plant growth. Studies of related genes in other species connect the family to chloroplast and vascular development, tillering and salt tolerance.
