Figure 7. Mutants with altered levels of abscisic acid (ABA) and gibberellic acid (GA) have altered germination time variability.

Distributions of germination times for indicated genotypes. cyp707a1-1 and cyp707a1-1 cyp707a2-1 mutants lack enzymes involved in ABA catabolism, while ga3ox-3 and ga3ox1-3 ga3ox2-1 mutants lack enzymes involved in GA biosynthesis. Plots show the percentage of all seeds that were sown, that germinated on a given day. Grey-coloured bars show the germination time distribution of seed batches from replicate mother plants. For Col-0 and each mutant, the mean coefficient of variation of germination times, mode days to germination and final percentage germination is shown (averaged across the replicate batches [n = 3]). Data are representative of at least two independent experiments for each genotype. Source data is provided in Figure 7—source data 1.
