Fig. 3. Effect of CPA on viability of soybean cells. Exponentially growing cells were treated with CPA (50 µM) for 24 hours (grey bars). Pre-treatment with 10 µM BAPTA-AM was carried out 1 hour before the 24-hour CPA treatment. Cells cultured without CPA were taken as a control (white bars). Data are means±s.d. of three independent experiments. Statistically significant at *P<0.05.
