abstract：:Glutathione (GSH) is one of the main antioxidants in plants. Legumes have the specificity to produce a GSH homolog, homoglutathione (hGSH). We have investigated the regulation of GSH and hGSH synthesis by nitric oxide (NO) in Medicago truncatula roots. Analysis of the expression level of gamma-glutamylcysteine synthet...
