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:RNA-seq technology was used to identify differentially localized transcripts from Xenopus laevis and Xenopus tropicalis stage VI oocytes. Besides the discovery of a group of novel animally enriched RNAs, this study revealed a surprisingly low conservation of vegetal RNA localization between the two frog species. mRNA profiles of Xenopus laevis and Xenopus tropicalis animal and vegetal oocyte halves were generated by RNA-seq technology. For Xenopus laevis, animal and vegetal oocyte RNA preparations from two different females were generated in duplicates. For Xenopus tropicalis, animal and vegetal oocyte RNA preparations from two different females were analyzed.

Project description:We report the application of paired-end RNA sequencing for high throughput profiling of the Xenopus transcriptome in 23 distinct developmental stages. In total, we obtained over 900 million reads and the deep coverage allowed us to examine the transcriptome in detail. First, we found that ~150 genes are transcribed before embryonic genome activation when transcription is generally thought to be repressed. Second, we discovered thousands of novel splice junctions, the majority of which modify existing gene structures. Third, we curated a confident set of 6686 non-coding transcripts in 3859 genomic loci. Many of these non-coding RNAs are also developmentally regulated, which suggests that they may play important roles during embryogenesis. Finally, we found hundreds of contigs that cannot be aligned to the reference genome, which indicates that the current genome (XenTro3) is still unfinished. Our results will aid in the full assembly and annotation of the Xenopus tropicalis genome.
