Metagenomics

Common card · No. 294140

Metagenomics is the study of all genetic material from all organisms in a particular environment, (environmental DNA) providing insights into their composition, diversity, and functional potential. Metagenomics has allowed researchers to profile the microbial composition of environmental and clinical samples without the need for time-consuming culture of individual species. Metagenomics has transformed microbial ecology and evolutionary biology by uncovering previously hidden biodiversity and metabolic capabilities. As the cost of DNA sequencing continues to decline, metagenomic studies now routinely profile hundreds to thousands of samples, enabling large-scale exploration of microbial communities and their roles in health and global ecosystems. Metagenomic studies most commonly employ shotgun sequencing though long-read sequencing is being increasingly utilised as technologies advance. The field is also referred to as environmental genomics, ecogenomics, community genomics, or microbiomics...
