To understand the range of human genetic and physiological diversity, the microbiome and the factors that influence the distribution and evolution of the constituent microorganisms must be characterized. At the conclusion of each program, deliverables transition to other sources of support or use by the broader scientific community. At present, metagenomic analyses of complex microbial communities are limited by the availability of suitable reference genomes, which are needed for confident assignment of the short sequences produced by the current generation of highly parallel DNA sequencers. Natl Acad. Second, it will be necessary to find better, faster and more scalable heuristics for generating huge phylogenetic trees that contain millions of sequences. The study, which included dozens of collaborators, was part of the second phase of the Human Microbiome Project (HMP). 72, 135143 (2006).

In particular, heterogeneous rates of evolution in different protein families pose substantial problems for search-based methods: considerable similarities at the primary-structure level might not persist over time, and the secondary and tertiary structures of the proteins are usually unknown, thus preventing the use of structure-based alignment techniques. Now customize the name of a clipboard to store your clips. This coupling of comparative metagenomics with germ-free animal models shows one way to proceed from in silico predictions to experimental tests of whole-community microbiome function. It requires coordination between scientists, governments and funding agencies.
