SR1 — Nicotiana attenuata

Summary

A4A49_00460 (SR1, NaSR1) on chromosome 7 of coyote tobacco encodes a protein with a NAF/FISL domain and a serine/threonine kinase domain, and is annotated with nucleoside diphosphate kinase activity, protein kinase inhibitor activity, and heat shock protein binding, among many other molecular functions. It is associated with responses to pH, reactive oxygen species biosynthesis, regulation of potassium transport, abscisic acid biosynthesis, systemic acquired resistance, and developmental processes involved in reproduction. The gene is linked to traits including drought sensitivity, alkali soil sensitivity, bacterial blight disease resistance, submergence tolerance, and mineral and ion transport. It localizes to the tonoplast, thylakoid, stress granule, and nuclear body. Related genes in other species are linked to pathogen resistance, abiotic stress tolerance, and light signaling.
