DHAR — Capsicum annuum

Summary

CaDHAR (T459_29115) on pepper chromosome 12 encodes a glutathione S-transferase DHAR3 chloroplastic protein with dehydroascorbate reductase and glutathione transferase activities, and belongs to the DHAR1/2/3/4 family. This gene is associated with ascorbate metabolism, the ascorbate-glutathione cycle, cellular oxidant detoxification, response to hydrogen peroxide, protein glutathionylation, positive regulation of salicylic acid-mediated signaling, fruit ripening, response to jasmonic acid, ozone, zinc, and symbiotic fungi, and acquisition of seed longevity. It has been connected to traits including net photosynthetic rate, plant height, root volume and length, stem diameter, and respiration rate, as well as phenotypes such as oxidative and drought stress tolerance, chilling injury tolerance, seed longevity, and ascorbate and glutathione redox state. The protein localizes to chloroplast envelope, stroma, apoplast, vacuole, plastid, mitochondria, and cytosol.
