Abiotic stress sensitivity of PCA22 transgenic plants. (A–C) Effect of mannitol, PEG, and ABA treatment on cotyledon greening. Seeds were sown on MS agar plates supplemented with 400 mM mannitol (A), 10% PEG (B), or 1 μM ABA (C), and were permitted to grow for 7, 8, and 9 days after germination (DAG). Seedlings with green cotyledons were counted (triplicates; n=50 each). Error bars represent the SD. Differences between WT and transgenic plants grown under the same conditions are significant at 0.05>P>0.01 (*) or P<0.01 (**).
