Germination rates of wild-type plants, tap46 mutants, complemented lines, and TAP46-overexpressing plants in the presence of ABA. A, Germination rates of wild-type (Col-0), tap46 mutants (tap46-1 and tap46-2), complemented lines of tap46-1 (Com1 and Com2), TAP46-overexpressing plants (OE1 and OE2), and abi5-1 mutant in the presence of 2 μm of ABA from day 3 to day 9 (D3–D9). B, Germination rates of wild-type (Col-0), tap46 mutants (tap46-1 and tap46-2), complemented lines of tap46-1 (Com1 and Com2), TAP46-overexpressing plants (OE1 and OE2), and abi5-1 mutant in the absence and presence of various concentrations of ABA on day 7. Three independent experiments were performed.
