GSH2 — Brassica juncea

Summary

BjGSH2 (BJUB07G32100S) on Indian mustard chromosome B07 encodes a glutathione synthase, an enzyme with glutathione synthase activity that also binds glutathione, ATP and magnesium, and forms homodimers. The gene is associated with glutathione anabolism, sulfate assimilation, sulfur metabolism, stress and jasmonic acid responses, and homeostasis. Its product localises to the plastid and cytosol. BjGSH2 is associated with photosynthetic rate, cadmium and ozone tolerance, endoplasmic reticulum stress response, root growth, seedling and plant development, and jasmonate hypersensitivity. Related genes in other species are linked to glutathione and phytochelatin biosynthesis, cadmium and cesium stress tolerance, and severe developmental phenotypes including seedling lethality and glutathione deficiency.
