Fig. 5From: Metatranscriptomic analyses reveal ruminal pH regulates fiber degradation and fermentation by shifting the microbial community and gene expression of carbohydrate-active enzymesmRNA expressions of the carbohydrate-active degrading enzymes. The top 10 enzymes were selected (a). Sequence counts were expressed as relative abundance (%). Heatmap shows enzymes that were significantly affected by pH effect and sample fractions (b). Rows are color coded according to Z-score. A Z-score change of + 1 is equal to one standard deviation above the row mean. Blue represents upregulation, and red represents downregulationBack to article page
