Project description:Raw RNAseq data from ferns sampled in Singapore. Organ specific samples were selected for assembly via denovo assembly for comparative transcriptomics.
Project description:To investigate the effect of Decitabine and SB939 treatment on the expression of endoretroviral elements. We treated 9 cell lines with DMSO, Decitabine, SB939 or a combination of Decitabine and SB939 and performed RNA-seq. This data was used to generate a denovo transcriptome assembly to identify novel mRNAs expressed from endoretroviral elements.
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:Whole Genome Sequencing and analysis of Pan-Drug Resistant Acinetobacter baumannii using a Hybrid Denovo Approach (Illumina and Nanopore)
Project description:Constructing high-quality haplotype-resolved genome assemblies has substantially improved the ability to detect and characterize genetic variants. A targeted approach providing readily access to the rich information from haplotype-resolved genome assemblies will be appealing to groups of basic researchers and medical scientists focused on specific genomic regions. Here, using the 4.5 megabase, notoriously difficult-to-assemble major histocompatibility complex (MHC) region as an example, we demonstrated an approach to construct haplotype-resolved assembly of the targeted genomic region with the CRISPR-based enrichment. Compared to the results from haplotype-resolved genome assembly, our targeted approach achieved comparable completeness and accuracy with reduced computing complexity, sequencing cost, as well as the amount of starting materials. Moreover, using the targeted assembled personal MHC haplotypes as the reference both improves the quantification accuracy for sequencing data and enables allele-specific functional genomics analyses of the MHC region. Given its highly efficient use of resources, our approach can greatly facilitate population genetic studies of targeted regions, and may pave a new way to elucidate the molecular mechanisms in disease etiology.
