High concentrations of NaCl immediately elevated cytoplasmic Ca activity in maize (Zea Mays L. cv Pioneer 3377) root protoplasts, as measured with the fluorescent probe Indo-1. The effect of salinity was inhibited by Li pretreatment but restored by inositol, suggesting that phosphoinositides mediate the stress response.
