Project description:Neosalanx taihuensis is widely distributed in freshwater and brackish water areas in China. Due to its high commercial value, it has been artificially introduced into many lakes and reservoirs, showing strong ecological adaptability. Here, a gap-free chromosome-level reference genome was constructed by combining short reads, PacBio HiFi long reads, Nanopore ultralong reads and Hi-C data. The reference genome of N. taihuensis was 397.29 Mb with a contig N50 of 15.61 Mb. The assembled sequences were anchored to 28 chromosomes. Furthermore, 20,024 protein-coding genes and 98.16% of the predicted genes were annotated in publicly available biological databases. This high-quality gap-free assembled genome will provide an essential reference for studying the evolution and ecological adaptability of N. taihuensis.

Genome sequencing of strain Cellulosimicrobium sp. TH-20 with ginseng biotransformation ability.

Project description:Biotransformation for increasing the pharmaceutical effect of ginsenosides is getting more and more attractions. Strain Cellulosimicrobium sp. TH-20 isolated from ginseng soil samples was identified to produce enzymes contributing to its excellent biotransformation activity against ginsenosides, the main active components of ginseng. Based on phylogenetic tree and homology analysis, the strain can be designated as Cellulosimicrobium sp. Genome sequencing was performed using the Illumina Miseq to explore the functional genes involved in ginsenoside transformation. The draft genome of Cellulosimicrobium sp. TH-20 encoded 3450 open reading frames, 51 tRNA, and 9 rRNA. All ORFs were annotated using NCBI BLAST with non-redundant proteins, Gene Ontology, Cluster of Orthologous Gene, and Kyoto Encyclopedia of Genes and Genomes databases. A total of 11 genes were selected based on the functional annotation analysis. These genes are relevant to ginsenoside biotransformation, including 6 for beta-glucosidase, 1 for alpha-N-arabinofuranosidase, 1 for alpha-1,6-glucosidase, 1 for endo-1,4-beta-xylanase, 1 for alpha-L-arabinofuranosidase, and 1 for beta-galactosidase. These glycosidases were predicted to catalyze the hydrolysis of sugar moieties attached to the aglycon of ginsenosides and led to the transformation of PPD-type and PPT-type ginsenosides.

Proteogenomics of Microbacterium sp. Viu2A strain and its response to uranium

Project description:This project is a proteomic comparison of Microbacterium sp. Viu2A exposed to 10 µM nitrate uranyl versus control condition without uranyl. Three sampling time points (30 min, 4h and 24h) were analyzed. The proteomics datasets were obtained using a protein database derived from the Microbacterium sp. Viu2A complete genome.
