Project description:The gut microbiota composition is unique to every individual but is shaped by common factors including diet, lifestyle, medication use, early-life determinants, living environment or genetics. Most of these factors may be influenced by ethnicity. This study explored variations in fecal microbiota composition in 6048 individuals with different ethnic backgrounds living in the same geographical area (Amsterdam, the Netherlands).
Project description:Quantitative proteomic experiments were performed on tryptic digests of proteins purified from the leaves of Arabidopsis thaliana. Wild type plants were compared to bzip28 bzip60 mutant plants. WT and bzip28 bzip60 mutant plants were infected with Drecslera gigantea and compared to non¬-infected control plants
Project description:In this study, C. gigantea miRNAs and their target genes were investigated by extracting RNA from young roots, tender stems, young leaves, and flower buds of C. gigantea to establish a small RNA (sRNA) library and a degradome library to further sequence. This study identified 194 known miRNAs belonging to 52 miRNA families and 23 novel miRNAs. Among the miRNA families, 158 miRNAs from 27 miRNA families were highly conserved and existed in a plurality of plants. In addition, 60 different targets for 30 known families and one target for novel miRNA were identified by high-throughput sequencing and degradome analysis in C. gigantea. Our analyses showed that conserved miRNAs have higher expression levels and more family members as well as more targets than other miRNAs. Meanwhile, these conserved miRNAs were found to be involved in auxin signal transduction, regulation of transcription, and other developmental processes in plants, which will help further understanding regulatory mechanisms of C. gigantea miRNAs. The samples were collected from the young roots, tender shoots, young leaves and flower buds of wild C. gigantea growing in Jiangsu Province. TRIzol reagent (Invitrogen, USA) was used to extract the total RNAs [20]. An Illumina next-generation sequencing system, i.e. the 1 G Genome Analyzer sequencing platform, was utilized for sRNA sequencing. An Illumina HiSeq 2000 (LC Sciences, USA) was used for degradome sequencing.
Project description:To explore the methylome differences of swine breeds with different traits of commercial interest, we sampled liver tissues from a Chinese well-known elite native breed of Enshi black pig, a Large White pig, and a Chinese wild boar living within the same environment at the same daya-old (90d).
