Metagenomics is the study of the genetic material of communities of organisms present in environmental samples. Given that most microbial organisms are not culturable, obtaining unbiased data on the biodiversity of samples relies on sequencing the pool of genetic material that is extracted from them. Phylogenetic analysis generally involves amplification of specific genes (often rRNA genes) followed by sequencing, whilst whole-genome sequencing aims to study the set of functional activities encoded in the sample. Metatranscriptomics is the study of all of the genes expressed in the sample.
The EBI Metagenomics resource provides a single access point to submit, analyse, visualise and retrieve metagenomics and metatranscriptomics datasets (Figure 1).
