New microRNAs in Drosophila
Ontology highlight
ABSTRACT: MicroRNAs (miRNA) are small, endogenous RNAs that regulate the expression of mRNAs posttranscriptionally. Evolutionarily new miRNAs, like new protein-coding genes, are dominantly expressed in reproductive organs. To dissect the evolutionary dynamics of new miRNAs in Drosophila spp, we sequenced small RNAs from two species of Drosophila, including four samples from reproductive organs and one sample from imaginal discs / CNS. miRNA expression profile shows vast majority of new miRNAs are specifically expressed in testes and/or ovaries, suggesting a role of sexual selection for new miRNA evolution.
