SR1 — Nicotiana attenuata

Summary

A4A49_03193 (NaSR1, also known as NaCIPK14, SNRK3.22, PKS5, and other synonyms) on chromosome 11 of coyote tobacco (Nicotiana attenuata) 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 other molecular functions. The gene is associated with response to pH, reactive oxygen species anabolism, regulation of potassium transport, regulation of abscisic acid anabolism, and regulation of systemic acquired resistance. It is linked to traits including drought sensitivity, alkali soil sensitivity, bacterial blight disease resistance, submergence tolerance, and mineral and ion transport. Localization evidence connects the product to the tonoplast, thylakoid, and stress granules. Studies of related genes in other species link the family to oxidative stress tolerance, pathogen resistance, and abiotic stress tolerance.
