GSH2 — Brassica juncea

Summary

BjGSH2 (BJUA09G66860S) on Indian mustard chromosome A09 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, and its product localises to plastids and cytosol. BjGSH2 is associated with photosynthetic rate, cadmium and ozone tolerance, endoplasmic reticulum stress response and morphology, seedling and plant development, root growth, jasmonate hypersensitivity, and 2,4-dinitrotoluene response. Studies of related genes in other species link the family to glutathione biosynthesis, cadmium resistance, stress tolerance, phytochelatin synthesis, and traits including net photosynthetic rate, chlorophyll content, transpiration rate, stomatal resistance, seed maturation, and seedling growth.
