Figure 3.

Cumulative radicle emergence of the TIP3 and TIP4;1 mutants and complemented lines in the presence of 75‐nM ABA. Seeds were incubated for 3 days at 5°C/dark on water to remove primary dormancy then transferred to 75‐nM ABA in buffer at pH 5.0 and cumulative radicle emergence recorded during incubation at 25°C/light over 11 days. (a) Response of the TIP3 single and double mutants and the complemented line YFP‐TIP3;2. (b) Response of the tip4;1 mutant and the complemented line YFP‐TIP4;1. In both cases, the wild type is Col‐0. Data are mean ± SE (n = 3). Absence of error bars indicates SE is smaller than the symbol
