Danio rerio egg microbiome variation
Microbiomes are integral to the fitness of many animals, yet little is known about the early-life microbiome assembly. What is known largely comes from studies in non-model organisms, where it is difficult to isolate host genetics and the environment as drivers of microbiome assembly. We used a popular vertebrate model, zebrafish (Danio rerio) to address the major drivers of early-life microbiome assembly.
