CXIP1 — Solanum lycopersicum

Summary

SlCXIP1 (CXIP1) on tomato chromosome 2 encodes a glutaredoxin family protein with a monothiol GRX-rel domain and thioredoxin-like fold. It exhibits calcium:proton antiporter activity, glutathione disulfide oxidoreductase activity, and 2Fe-2S cluster binding. The gene is associated with pigment accumulation, response to biotic stimulus, cellular manganese and zinc ion homeostasis, S-nitrosylation, and immune system processes. It localizes to the tonoplast, vacuole, chloroplast envelope and stroma, and mitochondria. SlCXIP1 is linked to traits including drought tolerance, submergence tolerance, oxidative stress response, germination rate, leaf elongation rate, stomatal resistance and opening, quantum yield, photochemical quenching, transpiration rate, cadmium concentration, and manganese sensitivity. It is also connected to phenotypes such as iron-sulfur cluster formation, embryo development and viability, phosphate homeostasis, cadmium tolerance, and abscisic acid sensitivity. Related genes in other species are linked to calcium transport, abiotic stress response, and cold and cadmium sensitivity.
