Changes in the content of secondary metabolites of fruits and seeds in response to autopolyploidization. The bars represent the log10-fold change in metabolite content from the induced-autopolyploid lines in comparison to their donor lines. The bars facing right (positive) indicate increased content, and the bars facing left (negative) indicate decreased content. Values are presented as the means ± se of six autotetraploid and six autohexaploid independent lines. The values in parentheses represent the m/z for each metabolite. NA, non-annotated.
