Abstract	The present study was conducted to evaluate the influence of salt or water stress conditions on the production of daidzein (4.7-dihydroxy isoflavone) or its glycoside (daidzin) and to obtain correlations with enzymes of Ca 2+ signaling phosphoprotein cascade in hairy root cultures of Psoralea corylifolia L (fabaceae). Culturing of hairy roots for five weeks in presence of salt (300 mM NaCl) decreased their growth, but nearly doubled daidzein production during the first two weeks of culture in comparison to untreated controls (p < 0.01). However, such changes could not be noted upon water stress caused by 5% polyethylene glycol. Salt stress-induced increase in daidzein production was associated with oxidative stress as evidenced by accumulation of reactive oxygen species, end products of lipid peroxidation, decreased ratio of reduced and oxidized glutathione and up-regulation of antioxidant enzymes such as superoxide dismutase and glutathione peroxidase. Simultaneous increases in intracellular Ca 2+ levels were concomitant with increased activities of Ca 2+ dependent protein kinases and calcineurin, but decreased activity of Ca 2+ - calmodulin dependent protein kinase. The results indicate correlations between salt stress-induced increase in daidzein production with oxidative stress and Ca 2+ - signaling events.
