PLS plot of the intestinal microbiota and analyzed parameters of individual mice at 22 weeks. Projections to latent structures (PLS) loadings biplot of the microbiota (T-RFs of the T-RFLP profile) and the physiological parameters (A through Q) of the individual mice in the small intestine (A) and caecum (B). For the small intestine PC1 explained 25.6% and PC2 15.6% of the variation. For caecum the PC1 explained 26.4% and PC2 16.4% of the variation. Blue open circle represents mice in the control group (Ctrl); orange open triangle for the group supplemented with L. plantarum DSM 15313 (Lp); green dot for the group supplemented green tea (GT); red triangle for the group supplemented L. plantarum DSM 15313 and green tea (Lp + GT). Letters denote metabolic parameters, A, body weight; B, body fat content; C, periovarian white adipose tissue; D, liver weight; E, spleen weight; F, caecum weight; G, liver cholesterol; H, liver TAG; I, plasma ALT; J, plasma cholesterol; K, plasma insulin; L, plasma glucose; M, plasma leptin; N, PPARα mRNA; O, PPARγ mRNA; P, CD36 mRNA; Q, SR-B1 mRNA. Symbol X denotes T-RFs. T-RFs having the biggest influence on the model are marked by numbers indicating the fragment size.
