PCA of the metabolic profiling data set. PCA was performed with a metabolite data matrix (351 metabolite-candidate peaks versus samples, relative levels as a variable) obtained from non-polar and polar fractions (Supplementary Table S2). (a) Score plot for PC1 vs. PC2. Percentage values in parentheses are the respective contribution ratios. (b) The factor loading plots for PC1 vs. PC2. Each plot represents 351 metabolite-candidate peaks, and the loading scores are given in Supplementary Table S3. PC, principal component; MR-CTB51A, MucoRice-CTB transgenic rice line 51A; MR-RNAi, MucoRice-RNAi; NPB-HP, O. sativa cv. Nipponbare grown hydroponically in a growth chamber; NPB-PF, Nipponbare grown in an open-air paddy field.
