Figure 4.

Comparison of root suberin monomer composition between the wild type (Col-0) and mutants myb92-1 myb93-1 and cyp86a1-1 cyp86b1-1. Mean values are shown in milligrams of suberin monomer per gram of delipidated dry residue (DR) from 3–4 replicate samples ± SE. A replicate consisted of a pool of 4 plants at 4 weeks of age. Inset represents the total poly-aliphatic Scheme 0. FA, fatty acids; DCA, dicarboxylic acids; ω-OH FA, omega-hydroxy fatty acids. Asterisks indicate p < 0.05 by Student’s t-test comparing the values of the mutants to wild-type (Col 0)
