ABA sensitivity of OsCPK9 -OX and OsCPK9 -RNAi rice lines. Three-day-old rice seedlings were treated with 1 μM or 3 μM ABA for 14 days and then photographed (A). Length and dry weight of roots and shoots of rice seedlings harvested after the 14-day ABA treatment (B). Data are means ± SE calculated from four independent experiments. Asterisks indicate significant difference between the WT and transgenic lines (*p <0.05; **p <0.01).
