SR1 — Nicotiana attenuata

Summary

A4A49_19558 (NaSR1, also known as NaCIPK14, PKS5, and SNRK3.19) on coyote tobacco chromosome 10 encodes a protein with a NAF/FISL domain and a serine/threonine kinase domain, annotated with nucleoside diphosphate kinase activity, protein kinase inhibitor activity, and proton-transporting ATPase activity. The gene is associated with responses to pH, reactive oxygen species biosynthesis, regulation of potassium transport, abscisic acid biosynthesis, and systemic acquired resistance. It is linked to traits including drought sensitivity, alkali soil sensitivity, bacterial blight disease resistance, submergence tolerance, and responses to various fungal diseases such as rice sheath blight and wheat stripe rust. Localization evidence connects the product to the tonoplast, thylakoid, and stress granules. Related genes in other species are linked to salt tolerance, heat stress response, and defense against bacterial and fungal pathogens.
