New insights into the enteric methane production based on the archaeal genome map of ruminant gastrointestinal tract

As one of the important components of ruminant gastrointestinal tract (GIT) microbiome, archaea are involved in many biological processes, especially methanogenesis. However, the diversity and individual metabolic characteristics of archaea in this habitat remain largely understudied, partly due to the lack of a unified reference genome catalog.
