Fig. 5: Effects of NR on the rat microbiota diversity.
A α-diversity calculated by the Shannon diversity index. *p < 0.05, **p < 0.01. Shown as median and quartiles (1st and 3rd) and the minimum and maximum by the whiskers. B PCoA plots of β-diversity based on Bray-Curtis distance matrix for the study period. Colors are according to diet and treatment groups. Axes indicate the proportion of variance explained. C Abundance heatmaps of differentially abundant features at the species level. n = 6–8.
