Primary metabolome changes in transgenic seeds. A, Principal component analysis of GC-MS metabolite profiling data of wild-type (WT) and SSE genotypes. Variance explained by each component is indicated in brackets; principal component analysis was based in 56 annotated metabolites. B, Changes in the contents of individual metabolites in mature dry seeds of both SSE genotypes. Data shown in A and B are means ± se of five replicates. The bars in B represent the log10-fold change in metabolites contents in seeds from both SSE genotypes compared to wild-type seeds. The bars facing right (positive) indicate increased content, and the bars facing left (negative) indicate decreased content. Significance was calculated using the two-way ANOVA test of P < 0.05 and identified by asterisks.
