ABA phenocopies the effects of NaCl. Germination time courses of etr1-6;etr2-3;ein4-4 triple mutants transformed with genomic DNA encoding a mutant etr1 transgene containing the indicated point mutation were determined. For comparison, data from the wild type, etr1-6;etr2-3;ein4-4 triple mutants, and triple mutants transformed with a wild-type genomic ETR1 (gETR1) transgene are included. Seeds were germinated in the presence or absence of 1 µm ABA. All experiments were performed in triplicate. The average percentage of seed germination ± sd at each time is plotted for each seed line.
