Hypothesis
The study aims to identify and characterize microRNAs in the evolutionarily basal insect Blattella germanica.
Conclusion
The study identified many known and novel microRNAs in Blattella germanica, with a significant number found in the ovaries.
Supporting Evidence
- 38 known miRNAs and 11 known miRNA*s were identified.
- 70 miRNA candidates conserved in other insects were found.
- 170 candidates specific to Blattella germanica were identified.
- Five novel miRNA precursors were validated by PCR and sequencing.
Takeaway
Researchers looked at tiny molecules called microRNAs in cockroaches to understand how they help control growth and development.
Methodology
The study used high throughput Solexa sequencing to analyze small RNA libraries from the whole body of last instar nymphs and adult ovaries.
Limitations
The genome of Blattella germanica has not been sequenced, which complicates the identification of miRNA precursors.
