Metabolite changes associated with the altered colour phenotype of IL6-3.
(A) Carotenoid profiles, obtained by HPLC-UV/Vis analysis, recorded at 450 nm; (i), M82; (ii), IL6-3. The chromatographic peaks and UV/Vis spectra are 1-lutein, 2-β-carotene and 3-lycopene. (B) Quantitative changes associated with pathway components. The position of the proposed step in the pathway up-regulated (the fruit specific lycopene β-cyclase, CYC-B) is indicated. (C) Physical map of chromosome 6, showing the position of IL6-3 and CYC-B. (D) PCA of the metabolomic dataset for Il6-3; (i) scatter diagram of the score values, highlighting the separation based on variance in chemical composition between IL6-3 (brown dots) and the M82 control (red dots). The % contribution of each component to the variance is shown (ii), loadings plot of variables with the identity of some of the variables annotated. Only variables contributing to a significant difference (p-value of < 0.05) are shown.
