Project description:In this study, we investigated the effects of the marine microalga Tisochrysis lutea F&M-M36 (T. lutea) on cardiometabolic components of pre-MetS induced by a high fat diet, and its underlying mechanisms.
Project description:To examine the mechanisms that control flower development, we sequenced the flower bud transcriptomes of ‘High Noon’, a reblooming cultivar of P. suffruticosa × P. lutea. Both full-length isoforms and RNA-seq were sequenced in 3 floral developmental stages. A total of 15.94 Gb raw data and 457.0 million reads were generated in full-length transcript sequencing and RNA-seq.
Project description:Porcine 60K BeadChip genotyping arrays (Illumina) are increasingly being applied in pig genomics to validate SNPs identified by re-sequencing or assembly-versus-assembly method. Here we report that more than 98% SNPs identified from the porcine 60K BeadChip genotyping array (Illumina) were consistent with the SNPs identified from the assembly-based method. This result demonstrates that whole-genome de novo assembly is a reliable approach to deriving accurate maps of SNPs.
Project description:Low-pass sequencing (sequencing a genome to an average depth less than 1× coverage) combined with genotype imputation has been proposed as an alternative to genotyping arrays for trait mapping and calculation of polygenic scores. To empirically assess the relative performance of these technologies for different applications, we performed low-pass sequencing (targeting coverage levels of 0.5× and 1×) and array genotyping (using the Illumina Global Screening Array (GSA)) on 120 DNA samples derived from African and European-ancestry individuals that are part of the 1000 Genomes Project. We then imputed both the sequencing data and the genotyping array data to the 1000 Genomes Phase 3 haplotype reference panel using a leave- one-out design. We evaluated overall imputation accuracy from these different assays as well as overall power for GWAS from imputed data, and computed polygenic risk scores for coronary artery disease and breast cancer using previously derived weights. We conclude that low-pass sequencing plus imputation, in addition to providing a substantial increase in statistical power for genome wide association studies, provides increased accuracy for polygenic risk prediction at effective coverages of ∼ 0.5× and higher compared to the Illumina GSA.

Project description:Genotyping-By-Sequencing (GBS) of three co-occurring Therophytes (Catananche lutea, Geropogon hybridus and Urospermum picroides)
Project description:Deep whole genome sequencing of Drosophila melanogaster inbred lines: DGRP-28, DGRP-307, DGRP-399, DGRP-57, DGRP-639, DGRP-712, DGRP-714, DGRP-852 and Virginizer (VGN). The lines were sequenced deeply giving between 54M and 92M reads to achieve a whole genome coverage that ranged between 74X and 125X. The sequencing was used for de novo genotyping.
Project description:Because mice with Pgr-Cre mediated double ablation of Insr and Igf1r are infertile and possess trapped oocytes in their corpora lutea, we performed RNA-seq to identify candidate pathways that contribute to ovulation failure.
Project description:For developing the more SNPs and new high-density genetic linkage map of tea plant, two parents and their 326 progenies and 147 registered tea cultivars was sequencing by newly developed Affymetrix Axiom genotyping technology
