Comparison of the water permeance of tomato cutin in red ripe fruits from wild-type and tomato EMS mutant plants. Data are shown as median values ± minimum/maximum (n = 8–10). Differences between the wild type (WT), cus1 mutants (cus1-a, cus1-b, and cus1-c), and cud1 were tested with the Mann-Whitney U test. Asterisks indicate significant differences from the wild type (*, P < 0.05).
