Fig. 5From: Characteristics of intestinal bacteriophages and their relationship with Bacteria and serum metabolites during quail sexual maturity transitionHeat maps illustrating the relationships between differential gut bacteriophage species and differential serum metabolites. The X-axis denotes serum metabolites, while the Y-axis refers to bacteriophage species. Significance levels are denoted as: *P < 0.05, **P < 0.01, and ***P < 0.001Back to article page
