Glutathione metabolism in soybean callus-cultures as affected by salinity

El-Enany, A.E. (Assiut Univ. (Egypt). Botany Dpt.)
Induction and growth of soybean callus cultures were influenced by NaCl. Protein content was raised as NaCl was increased in the Murashige and Skoog medium. Total sulfhydryl group (-SH) and glutathione (GSH) concentrations were also increased in NaCl treated cultures. The affinity of glutathione reductase (GR) for oxidized glutathione (GSSG) was gradually increased as NaCl level aws raised in the medium. The GSH/GSSG ratio was raised significantly as the result of GR activity. The increase in GR activity may constitute an adaptative response of soybean callus to NaCl.
