Fig. 2. Principal component scores plot of PC1 (75.5%) against PC2 (16.2%) from PCA
of all metabolites identified by LC–MS for the various transgenic genotypes and
controls, with samples labelled according to line number. Where SGT1 lines = filled
black squares; SGT2 lines = filled grey squares; SGT3 lines = open squares; C = tissue
culture (TC) control; W = wild-type (WT) control; E = empty vector (BIN+) controls.
