DHAR3 — Glycine max

Summary

GLYMA_18G040100V4, designated GmDHAR3, encodes a dehydroascorbate reductase with glutathione transferase activity, belonging to the DHAR1/2/3/4 and glutathione S-transferase families. The enzyme is associated with ascorbate metabolism, the ascorbate-glutathione cycle, glutathione anabolism, protein glutathionylation and oxidation, cellular oxidant detoxification, metabolic burst, regeneration, stomatal closure, chlorophyll fluorescence, lipid homeostasis and metabolism, nitric oxide storage, and positive regulation of salicylic acid-mediated signaling. It is linked to seed longevity and viability, drought and salt tolerance, root yield and length, shoot and biomass yield, leaf relative water content and water potential, net photosynthetic and transpiration rates, water use efficiency, stomatal resistance, and chlorophyll, carotenoid, proline, and ascorbate content. The protein localizes to the chloroplast envelope, stroma, plastid, and cytosol. Related genes in other species are linked to high light stress tolerance.
