AAT1 — Zea mays

Summary

ZM00001EB427800 (ZmAAT1) on maize chromosome 10 encodes a cationic amino acid transporter C-terminal domain-containing protein with amino acid permease activity, localised to the plasmalemma. The gene is associated with a wide range of biological processes, including amino acid transport, DHN-melanin biosynthesis, toxin anabolism, asexual sporulation, nitrogen fixation, gluconeogenesis, photorespiration, and the MAPK cascade. It is linked to numerous agronomically important traits, such as grain yield, grain number, ear length, plant height, brittle endosperm, leaf chlorophyll content, carotenoid content, anthocyanin content, proline content, and responses to salt, drought, heat, and oxidative stress, as well as salinity tolerance and germination rate.
