AAT1 — Zea mays

Summary

ZM00001EB136100 (AAT1) on maize chromosome 3 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 osmotic stress response and abscisic acid response. 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, and SALTTL. Associations also include 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, salt tolerance, leaf senescence, plant biomass, gamma irradiation tolerance, viral resistance, flowering time, reproductive fitness, resistance to Colletotrichum higginsianum, resistance to Pseudomonas syringae, and stomatal closure. The encoded protein localises to the nuclear envelope, tonoplast, plant-type vacuole, endoplasmic reticulum, mitochondria, membrane, plasmalemma, and cytoplasm.
