Supplementary Figure 7

The total amount of wax, a, and the levels of alkanes and triterpenoids, b, were not significantly different between the azygous wild type control (shaded) and PL::RNAi (clear) bars, as was the case for almost all individual wax compounds. The only statistically significant (P=0.05; two-tailed t-test) differences were in the abundance of 32 and 33 carbon alkanes, but the magnitude of the differences were too small to account for the differences in fruit firmness based on transpirational water loss. We conclude that the elevated expression of CER1, which is involved in cuticular alkane biosynthesis in the RNAi line did not have a major effect on cuticle function or composition. Error bars are s.e.m. Four individual fruits, represented by dots, were sampled from the azygous and PL::RNAi PL5 genotypes.
