Heat map showing the most abundant operational taxonomic units (OTUs, at least 500 total) in the control (n = 4), peach (n = 4) and plum (n = 4) groups.

<p>Colors represent differences in relative abundance within samples (red: higher; white: median; blue: lower).</p

Oligonucleotides used in this study for qPCR analysis.

UPGMA hierarchical clustering using the unweighted Unifrac distance matrix.

<p>The colors represent different jackknife support: red (75–100% support); yellow (50–75%); green (25–50%); blue (<25% support). The bar represents community dissimilarity.</p

Quantitative real-time PCR results for Ruminococcaceae (family, A), <i>Faecalibacterium</i> (B), <i>Lactobacillus</i> (C), <i>Turicibacter</i> (D), Bacteroidetes (phylum, E) and <i>Bifidobacterium</i> (F) in the lean (n = 6), control obese (n = 8), peach (n = 7), and plum (n = 9) groups.

<p>Error bars represent the median and interquartile ranges (all results were normalized to qPCR data for total bacteria). Columns not sharing the same superscript are significantly different (p<0.05). *Significantly higher than all other groups.</p

Principal Coordinate Analysis (PCoA) plots of the unweighted Unifrac distance matrix.

<p>The plots show each combination of the first three principal coordinates. Red (square): control; orange (circle): plum; blue (upright triangle): peach.</p

Rarefaction plots of 16S rRNA gene sequences obtained from fecal samples.

<p>Lines denote the average of each group; error bars represent the standard deviation. This analysis was carried out using a randomly selected 2489 sequences per sample.</p

Composition of fecal microbiota in the control (n = 4), peach (n = 4) and plum (n = 4) groups at the phylum level.

<p>Bars represent median percentage of sequences. The y axis (percentage of sequences) was modified to also show the low abundant phyla.</p
