Dietary broccoli mediates divergence of cecal microbial community structure in Ahr^b/b and Ahr^d/d mice. Pie chart representation and relative abundance of bacterial phyla from control or broccoli-fed (A) Ahr^b/b and (D) Ahr^d/d mice. Broccoli impacts Firmicutes/Bacteroidetes ratio and overall microbial diversity as determined by the Shannon Diversity Index found in (B) Ahr^b/b and (E) Ahr^d/d mice. Relative 16S rDNA abundances of microbial taxa that are significantly altered by administration of broccoli diet in (C) Ahr^b/b and (F) Ahr^d/d mice. Data represent the mean relative 16S rDNA abundance (%) (n=8 per genotype/diet group) ± SEM.
