title: Murine gut microbiota-diet trumps genes.
abstract: Both environmental factors and host genetics shape the composition of gut microbiota in mammals, but what matters more is insufficiently understood. In this issue of Cell Host & Microbe, Carmody et al. (2015) show that diet can overrule genotype-related differences in gut microbiota composition in different mouse populations.
