Hypothesis
Can high-throughput sequencing technology reveal novel transcripts in marine metatranscriptomes?
Conclusion
The study confirms that metatranscriptomic studies of natural microbial communities are feasible and can uncover a significant number of novel gene families.
Supporting Evidence
- The study processed a total of 323,161,989 base pairs from marine microbial communities.
- 99.92% of the RNA extracted was mRNA, indicating high enrichment.
- 91% of the identified large gene families were novel.
- The methodology allows for the exploration of both structure and function of microbial communities.
Takeaway
Scientists studied tiny ocean organisms to find new genetic information using advanced sequencing technology, and they discovered many new genes that had never been seen before.
Methodology
The study used GS-FLX Pyrosequencing technology to analyze four DNA and four mRNA samples from a controlled coastal ocean study.
Potential Biases
Potential biases include the time required for filtration and the amplification process that could introduce artefactual sequences.
Limitations
The study may have biases due to the methodology used for RNA extraction and amplification.
