Definition

Metatranscriptomics is the study of RNA transcripts obtained from environmental samples, providing insight into gene expression and regulation in microbial communities. It helps to understand the functional activity of microorganisms in their natural habitats.

5 Must Know Facts For Your Next Test

  1. Metatranscriptomics helps identify active metabolic pathways in microbial communities.
  2. It can reveal how environmental changes influence microbial gene expression.
  3. Techniques often involve high-throughput sequencing of RNA (RNA-Seq).
  4. Data from metatranscriptomics can be used to explore community-wide responses to stress or pollutants.
  5. Metatranscriptomics complements metagenomics by focusing on functional rather than genetic potential.
