Fig. 2From: Metatranscriptomic analysis of colonic microbiota’s functional response to different dietary fibers in growing pigsBray-Curtis PCoA plot of colonic bacteria of the abundant genes. The percentages in the axis labels represent the percentages of variation explained by the principal components. A closer proximity of dots indicates higher similarity.
