Response of the ppr96 mutants to salt stress. (A) and (B) Verification of the T-DNA insertion in the ppr96 mutants. Positions of T-DNA insertions in the At2g03380 gene, and PPR96 expression was not detected in mutants plants. (C–F) Germination rates of seeds after 7 days in the presence or absence of NaCl. (G) Phenotypic comparison of root lengths of plants grown on MS medium with or without NaCl. Images were recorded on day 7 after the transfer of 7-day-old seedlings from ½ MS medium to plates containing NaCl. Bars = 1 cm. (H) Effect of different NaCl concentrations on root growth in Col-0 and mutant plants. Data represent means ± SD (n = 30). Student's t-tests were used to generate the P-values. ^*P < 0.05; ^**P < 0.01.
