Project description:Transposable elements comprise a large proportion of animal genomes. Transcripts of transposable elements are a source for the synthesis of endogenous siRNAs and piRNAs. In order to determine if small RNAs mapped to expressed Tc1-like elements are present during early Xenopus tropicalis development, we used Illumina (Solexa) to sequence small RNAs from gastrula-stage embryos. We obtained about 17 million reads that mapped perfectly to the genome. Small RNAs mapped to selected transposable elements were characterized and the expression of selected small RNAs was experimentally verified during development. This is the first deep sequencing experiment for small RNAs in the Xenopus tropicalis gastrula. Analysis of small RNAs expressed in the Xenopus tropicalis gastrula.

Project description:Here we report on genome-wide small RNA and transcriptome profiling of blastula, gastrula and neurula-stage Xenopus tropicalis embryos using deep sequencing. By combining bioinformatic analysis of the small RNA-seq dataset with experimental validation, we identify novel microRNAs and Piwi-interacting RNAs. We show that microRNA expression is highly dynamic and spatially localized in early embryos in contrast to Piwi-interacting RNAs, and we validate a novel microRNA prediction pipeline. We go on to identify a new class of small intronic non-coding RNAs, that we name sincRNAs. On a genome-wide scale we find that genes containing sincRNA clusters are transcriptionally repressed. Our data suggest a novel mechanism of sincRNA-mediated gene silencing in vertebrates. Examination of small RNAs and mRNA at 3 stages of Xenopus embryonic development.
