FTIR analyses of pericarp cell walls from fruits at the RR stage. (A) Representative FTIR spectra of pericarp cell walls from WT1 and transgenic lines (TFM7-OE4 and TFM7-CS1). (B and C) PCA scores plot in principal component analysis (PCA) of FTIR spectra. Scores obtained on PC1-PC2 (B) or PC1-PC3 (C) clearly discriminated transgenic TFM7-CS spectra from TFM7-OE and WT spectra. (D) PC1 loading for analyzed characteristic peaks in FTIR spectra. Exploratory PCA was performed using the complete set of 54 FTIR spectra (18 FTIR spectra for each population).
