Gene ontology enrichment analysis of differentially expressed genes. Selected GO-terms, enriched in genes up-regulated (a) and down-regulated (b) in rumen of buffaloes fed a TMR + green feed (Treated) in comparison with those fed the TMR diet (Control), are shown. GO terms were classified as molecular function (purple bars), cellular component (green bars) and biological process (blue bars). Bar graphs indicate the statistical significance of the enrichment, as -log10 (adj p-value). Vertical yellow bars indicate the cut-off level for significance (p < 0.05, adjusted by Benjamini-Hochberg correction)
