Effect of TOC1 on stomata size. A: Simulated time courses of stomata aperture in wild type, TOC1-ox and toc1 mutant under 12 L:12D cycle for ABA = 1.3. TOC1-ox was simulated at n16 = 0.3. B: Experimental data on stomata conductance in wild type, TOC1-ox and toc1 mutant in absence (-) and presence (+) of 5 μM of exogenous ABA. Data are redrawn from .
