Figure 5.

Seed germination and postgermination growth in response to salt and ABA treatments in HSFA6 mutants. A, Seed germination (%) with either 1 μm ABA or 200 mm NaCl treatment. Water treatment was used as a control. B, Seedling growth with 0.5 to 1 μm ABA on plates was photographed at day 12 after planting. abi4-1, an ABA-insensitive mutant (Col ecotype), was used as reference. C, Cotyledon greening (%) with 150 mm NaCl on plates was measured at day 12 after planting. Data are means ± sd of three biological replicates. *Significant at P < 0.05 compared with the Col.
