Abstract
AbstractThe subterranean world hosts up to one-fifth of all biomass, including microbial communities that drive transformations central to Earth’s biogeochemical cycles. However, little is known about how complex microbial communities in such environments are structured, and how inter-organism interactions shape ecosystem function. Here we apply terabase-scale cultivation-independent metagenomics to aquifer sediments and groundwater, and reconstruct 2,540 draft-quality, near-complete and complet

Abstract
Significance Mealybugs are plant sap-sucking insects with a nested symbiotic arrangement, where one bacterium lives inside another bacterium, which together live inside insect cells. These two bacteria, along with genes transferred from other bacteria to the insect genome, allow the insect to survive on its nutrient-poor diet. Here, we show that the innermost bacterium in this nested symbiosis was replaced several times over evolutionary history. These results show that highly integrat
