DHAR — Solanum lycopersicum

Summary

SlDHAR (SOLYC05G054760.4) encodes a dehydroascorbate reductase, a member of the DHAR1/2/3/4 family with glutathione S-transferase and thioredoxin-like domains, possessing dehydroascorbate reductase, glutathione transferase, glutathione binding and copper binding activities. In tomato, this gene is associated with salt stress tolerance and has been linked to numerous processes including ascorbate and glutathione metabolism, the ascorbate-glutathione cycle, the xanthophyll cycle, protein glutathionylation, oxygen metabolism, nitrogen fixation, polyamine metabolism, and positive regulation of salicylic acid-mediated signaling. It is also associated with traits such as fruit firmness, fruit size and shape, carotenoid and flavonoid content, sugar and starch content, photosynthetic ability, quantum yield, water use efficiency, biomass yield, root and shoot growth parameters, leaf relative water content, germination rate, and seed longevity. The protein localises to the chloroplast, mitochondria, apoplast, vacuole, plastid, cytosol and plasma membrane.
