Project description:Chromatin, DNA and RNA were extracted from young A. alpina Pajares primary stem leaves. Chromatin and DNA methylation immunoprecipitation experiments were performed using commercially available antibodies and analyzed by Illumina sequencing (ChIP-seq and MeDIP-seq). Transcriptome data were generated by RNA-seq. ChIP-seq analysis of H3K4me3, H3K27me3 and H3K27me1 enrichment profiles and MeDIP-seq analysis of 5mC enrichment profiles in 2 biological replicates. RNA-seq analysis of mRNA levels in 1 biological replicate.
Project description:Transcriptomic profile of Arabis alpina apex enriched material. We compared apices from plants grown for 2 weeks in long days (20M-BM-0C) (juvenile) with apices from plants grown for 8 weeks in long days (20M-BM-0C) (adult) and apices from plants grown for 2 weeks and then shifted in vernalization for 4 weeks with apices from plants grown for 8 weeks and than shifted to vernalization for 4 weeks. 2x2 factorial design. 2 starting ages (2 weeks and 8 weeks) and 2 developmental conditions (before and after vernalization). 4 biological replicates for each condition (16 arrays). Reference: pool of the 16 arrays.

Project description:Analyses of new genomic, transcriptomic or proteomic data commonly result in trashing many unidentified data escaping the ‘canonical’ DNA-RNA-protein scheme. Testing systematic exchanges of nucleotides over long stretches produces inversed RNA pieces (here named “swinger” RNA) differing from their template DNA. These may explain some trashed data. Here analyses of genomic, transcriptomic and proteomic data of the pathogenic Tropheryma whipplei according to canonical genomic, transcriptomic and translational 'rules' resulted in trashing 58.9% of DNA, 37.7% RNA and about 85% of mass spectra (corresponding to peptides). In the trash, we found numerous DNA/RNA fragments compatible with “swinger” polymerization. Genomic sequences covered by «swinger» DNA and RNA are 3X more frequent than expected by chance and explained 12.4 and 20.8% of the rejected DNA and RNA sequences, respectively. As for peptides, several match with “swinger” RNAs, including some chimera, translated from both regular, and «swinger» transcripts, notably for ribosomal RNAs. Congruence of DNA, RNA and peptides resulting from the same swinging process suggest that systematic nucleotide exchanges increase coding potential, and may add to evolutionary diversification of bacterial populations.
