Total poly-aliphatic suberin in roots of wild-type and suberin mutants. Mean values of total suberin are given in milligrams of suberin per gram of delipidated dry residue (DR) from 3–4 replicate samples ± SE. Each replicate consisted of roots from four pooled plants at 4-weeks old. ANOVA results indicated significant interactions between genotype and treatment effects (Table S1). Asterisks indicate significant differences by Student’s t-test at p < 0.05 comparing control and treatment.
