AAT1 — Zea mays

Summary

ZM00001EB197320 (ZmAAT1, also known as CAT3, CAT4, CAT5, CAT6, CAT10, CAT11, AAT1, CAT1, CAT2) on maize chromosome 4 encodes a basic amino acid permease with L-lysine, L-glutamate, and general amino acid transmembrane transporter activity, belonging to the AA/rel_permease1 family. The gene is associated with amino acid transport, cellular amino acid homeostasis, L-arginine import, and responses to osmotic stress and abscisic acid. It has been linked to brittle endosperm, plant color, ear length, leaf chlorophyll content, carotenoid content, salt response, proline content, anthocyanin content, salinity tolerance, heat tolerance, germination rate, grain number, oxidative stress response, root length, chlorophyll content, plant height, grain yield, salt tolerance, drought tolerance, cold tolerance, senescence, oxidative stress tolerance, stomatal development, catalase activity, seed germination, hydrogen peroxide accumulation, peroxisome aggregation, programmed cell death, hydrogen peroxide scavenging, leaf amino acid concentration, circadian rhythm, hypersensitive response, amino acid concentration, root growth, plant growth, circadian clock-regulated gene expression, hydrogen peroxide tolerance, salicylic acid accumulation, leaf senescence, plant biomass, gamma irradiation tolerance, viral resistance, flowering time, reproductive fitness, resistance to Colletotrichum higginsianum, resistance to Pseudomonas syring
