This work examines the involvement of haem oxygenase-1 (HO-1) in salicylic acid (SA)-induced alleviation of oxidative stress as a result of cadmium (Cd) stress in alfalfa (Medicago sativa L.) seedling roots. CdCl(2) exposure caused severe growth inhibition and Cd accumulation, which were potentiated

Seeds of soybean (Glycinemax L.) exposed to 50 mg/L (Cd50), 100 mg/L (Cd100) and 200 mg/L (Cd200) cadmium solution for 24, 48, 72 and 96 h were examined with reference to Cd accumulation, oxidative stress and antioxidative responses. Soybean seeds accumulated Cd in an exposure time-and dosage-depend

In plants and other organisms, glutathione (GSH) biosynthesis is catalysed sequentially by γ-glutamylcysteine synthetase (γECS) and glutathione synthetase (GSHS). In legumes, homoglutathione (hGSH) can replace GSH and is synthesized by γECS and a specific homoglutathione synthetase (hGSHS). The s
… Homoglutathione (hGSH) is present in some leguminous plants including soybean and bean. … However, hGSH synthesis in non-leguminous plants has not been reported so far. … We constructed transgenic tobacco plants expressing soybean hGSH synthetase (hGSHS). … Although the transgenic tobacco plants exhibited higher hGSHS activity than glutathione (GSH) synthetase activity, hGSH content was much lower than GSH content. …

… The function of homoglutathione (γGluCysβAla, hGSH) and hydroxymethylglutathione (γGluCysSer, HMGSH) for the photoreduction of H_2O_2 was investigated. … Five to ten percents of the total leaf tripeptide were found in the chloroplasts of the hGSH species Glycine max and Phaseolus coccineus and of Triticum aestivum, a species which has HMGSH in addition to GSH. …
