GCN2 — Nicotiana attenuata

Summary

A4A49_01453 (GCN2) in coyote tobacco (Nicotiana attenuata) on chromosome 7 encodes a eukaryotic translation initiation factor 2alpha kinase with ATP-binding activity, belonging to the protein kinase superfamily. The gene is associated with abscisic acid (ABA) anabolism and signaling, stomatal closure, seed germination, translation initiation, protein synthesis, and response to cadmium. The encoded protein localizes to the cytosol and nucleus. GCN2 is associated with abscisic acid content, leaf relative water content, stomatal opening, chlorophyll content, and drought tolerance.
