Metatranscriptome sequencing

Unraveling gene expression in microbial populations with the power of NGS 

What is metatranscriptomics?

Metatranscriptomics is the collective study of expressed mRNA from complex microbial communities.1 Using metatranscriptome sequencing to study gene expression in a microbial population, researchers can gain important insights on how microbes respond to a given environment at a specific time. Sequencing RNA from microbiomes can reveal not only which microbes are present, but also their functional activities.

Discover the potential of community-level transcriptional information

Powered by next-generation sequencing (NGS) technologies, metatranscriptomics is a research field that spans diverse applications in agriculture, biotechnology, medicine, and more.1-4 In addition to providing data about a complex microbial community’s behavior and function, metatranscriptome sequencing can also provide valuable information about the community's environment or host.

Given the vast number (millions) of genes whose regulatory systems are not yet understood, metatranscriptomics is poised to make critical biological insights at the community level from native environments.

Metatranscriptome FAQs

Metagenomics is the study of all the genes found within a microbial population sample.5 In contrast, metatranscriptomics is the study of expressed genes, or the transcriptome, of a population.1

16S rRNA sequencing is a specific method that targets the 16S rRNA gene, which is only found in prokaryotes (ie, bacteria and archaea).6 Unlike metatranscriptomics or metagenomics, 16S rRNA sequencing cannot detect other microbes such as viruses and fungi. Although this method is not as susceptible to host DNA contamination, it is limited in detecting functional information and identifying strains/variants compared to metatranscriptomic or metagenomic sequencing methods.
