ANT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0161240, symbol ANT1 (also known as HvANT1 or HvANT2), encodes an aromatic amino acid transmembrane transporter on barley chromosome 2H. The product belongs to the AA_transpt_TM family and exhibits amino acid permease activity, localising to the vacuolar and ER membranes. In barley, ANT1 is associated with grain pericarp colour and linked to melanin, anthocyanin, flavonoid and phenylpropanoid anabolism, as well as amino acid membrane transport, RNA transport, pigmentation and response to nematodes. Associations also connect the gene to grain yield, plant growth and flavonoid and anthocyanin content. Studies of related genes in other species link the family to auxin transport, chloroplast and vascular development, tillering and salt tolerance.
