Project description:The genome of two isogenic lines from Aedes aegypti from Ile Royale, French Guiana, with a marked difference in resistance to deltamethrin was investigated in order to understand the genetic basis of this phenotypic difference. Genomic sequencing was performed both with Illumina short, paired reads and with Minion long reads.
Project description:These findings establish minion as a novel microprotein required for muscle development, and define a two-component program for the induction of mammalian cell fusion.
Project description:Here we describe CapTrap-Seq, an experimental workflow designed to address the problem of reduced transcript end detection by long-read RNA sequencing methods, especially at the 5' ends. We apply CapTrap-Seq to profile transcriptomes of the human heart and brain and we compared the obtained results with other library preparation approaches. CapTrap-Seq is a platform-agnostic method and here tested the method by using 3 different long-read sequencing platforms: MinION (ONT), Sequel (PacBaio) and Sequel II (PacBio).
Project description:The aim of this study was to identify TBBPA-degrading organisms in a complex microbial community by a metagenome-based functional metaproteomic approach, using protein-based stable isotope probing (protein-SIP). Firstly, the degradation kinetics were evaluated in order to simulate the decrease of residual mass of the labelled compound based on experimental data. In sequence, a metagenome was generated, and biomass was collected in different time-points for protein-SIP in incubations with 13C-TBBPA. This approach allowed for the identification organisms assimilating labelled carbon from the cometabolic degradation of a micropollutant.
Project description:To evaluate targeted MinION next generation sequencing as a diagnostic method for detection of pathogens in human blood and plasma, human blood or plasma samples were spiked with measured amounts of viruses, bacteria, protozoan parasites or tested pathogen-free as negative controls. Nucleic acid was extracted from samples and PCR amplification performed in multiplex primer pools with a procedure described in ArrayExpress experiment submission ID 18379. The PCR products were used for library preparation. The libraries sequenced on an Oxford Nanopore MinION. The passed reads aligned with a custom reference file to determine the identity of the pathogen in the sample.
Project description:S. meliloti strains with a bi- and monopartite genome configuration were constructed by consecutive Cre/lox-mediated site-specific fusions of the secondary replicons. Beside the correct genomic arrangements, these strains and precursors were tested for variations in the nucleotide sequence. Futher, a marker fequency analysis was performed to test if replication is initiated at all origins and to determine the replication termination regions of the triple replicon fusion molecule. To gain the sequence data for these analyses, respective strains were applied to whole genome sequencing using an Illumina MiSeq-System and Oxford Nanopore (MinION) sequencing technology.
Project description:To investigate the effect of aging on mitochondrial gene expression we isolated liver mitochondria from 4 12-week and 4 65-week C57BL/6N WT mice. We then isolated RNA and prepared the barcoded library using PCR-cDNA Barcoding Kit SQK-PCB109 and ran it on MinIOn R9.4.1 Flow cells.
