Drosophila melanogaster small RNA sequence from 14 libraries

ABSTRACT: High-throughput sequencing of Drosophila melanogaster small RNAs. total RNA, ~18-26nt RNAs isolated using PAGE, ligation to adapters requires 5' monophosphate and 3' OH Small RNAs were sequenced from D. melanogaster heads (male and female), body (male and female), S2 and Kc cells and different stages of embryo. Raw sequences were clipped by 3' linker sequences recognition, and select clipped sequences longer than 18 nt

Endogenous RNA interference provides a somatic defense against Drosophila transposons.

Chung Wei-Jen WJ Okamura Katsutomo K Martin Raquel R Lai Eric C EC

Current biology : CB 20080522 11

<h4>Background</h4>Because of the mutagenic consequences of mobile genetic elements, elaborate defenses have evolved to restrict their activity. A major system that controls the activity of transposable elements (TEs) in flies and vertebrates is mediated by Piwi-interacting RNAs (piRNAs), which are approximately 24-30 nucleotide RNAs that are bound by Piwi-class effectors. The piRNA system is thought to provide primarily a germline defense against TE activity.<h4>Results</h4>Here, we describe a ...[more]

The birth and death of microRNA genes in Drosophila

Project description:MicroRNAs (miRNAs) are small, endogenously expressed RNAs that regulate mRNAs post-transcriptionally. The class of miRNA genes, like other gene classes, should experience birth, death and persistence of its members. We carried out deep sequencing of miRNAs from three species of Drosophila, and obtained 107,000 sequences that map to no fewer than 300 loci that were not previously known. We observe a large class of miRNA genes that are evolutionarily young, with a rate of birth of 12 new genes per million years (Myr). Most of these new miRNAs originated from non-miRNA sequences. Among the new genes, we estimate that 96% disappeared quickly in the course of evolution; only 4% of new miRNA genes were retained by natural selection. Furthermore, only 60% of these retained genes became integrated into the transcriptome in the long run (60 Myr). This small fraction (2.5%) of surviving miRNAs may later on become moderately or highly expressed. Our results suggest that there is a high birth rate of new miRNA genes, accompanied by a comparably high death rate. The estimated net gain of long-lived miRNA genes, which is not strongly affected by either the depth or the breadth (number of tissues) of sequencing, is 0.3 genes per Myr in Drosophila Keywords: 454 microRNA deep sequencing Three small RNA samples from male heads of D. melanogaster, D. simulans and D. pseudoobscura were analyzed. The small RNAs were sequenced by 454 technology. After removing the flank adaptor sequences, the inserted sequences greater than 18nt were extracted.
