Microbiota changes induced by diet depend on the genetic background. Two-dimensional PLS-DA score plots constructed using the variable diet in the fast- (a), intermediate- (b), and slow-growth (c) families separately, representing the distribution of the samples between the first two components in the model. The goodness of fit and validation by the permutation test can be found in Additional file 4: Figure S3C–H. Heatmaps represent the abundance distribution (Z-score) of the OTUs identified to be driving the separation by diet in fast- (d), intermediate- (e), and slow-growth (f) families. Control (D1) and plant-based diets (D2) are represented in black and red, respectively
