DHAR — Brassica oleracea

Summary

BoDHAR (BOLC102_C08P028950.1) on cabbage chromosome 8 encodes a dehydroascorbate reductase with glutathione transferase activity and copper binding capacity, belonging to the DHAR1/2/3/4 family. The gene is associated with the ascorbate-glutathione cycle, ascorbate metabolism, protein glutathionylation, cellular oxidant detoxification, and responses to hydrogen peroxide, ozone, jasmonic acid, zinc, and symbiotic fungi. It is linked to regulation of salicylic acid-mediated signaling, symbiotic processes, seed longevity, and chlorophyll fluorescence. Localization evidence connects the product to the cytosol, chloroplast stroma, mitochondria, apoplast, vacuole, nucleus, and plasmalemma. Associations with photosynthetic rate, drought stress tolerance, abiotic stress tolerance, seed longevity, and ascorbate and glutathione redox states have been observed. Related genes in other species are linked to drought tolerance, aluminum tolerance, and oxidative stress tolerance.
