De Novo Whole Genome Sequencing Service

What Is De Novo Whole Genome Sequencing

De novo sequencing, also known as whole-genome sequencing, refers to the process of sequencing an organism without any prior reference sequence information. Through bioinformatics analysis methods such as assembly and alignment, the genomic sequence of the species can be obtained. By using whole-genome de novo sequencing technology, the complete genomic sequences of animals, plants, bacteria, and fungi can be obtained, thereby advancing the research of these species. Once the whole-genome sequence is completed, a genomic database for the species can be constructed, providing an efficient platform for post-genomic studies of the species and supplying DNA sequence information for subsequent gene mining and functional validation. With the use of next-generation high-throughput sequencing technologies, it is possible to efficiently and cost-effectively obtain the genomic sequences of all species, including animals, plants, bacteria, and fungi, thereby promoting research on these species.

1.Comparative Genomic Analysis

Using the progressiveMauve software, the chromosome sequences of 9 strains of Escherichia coli O104:H4 isolates are aligned to show information on mobile genetic elements and genomic variable regions. By utilizing the core SNP (Single Nucleotide Polymorphism) site information, a maximum likelihood phylogenetic tree is constructed to reveal the evolutionary relationship among the strains.

2. Repeat Sequence Analysis

Two methods, de novo prediction and database-based alignment, are employed to analyze the transposable elements (TEs) in the genome sequences of the Natal longhorned beetle and the Dampwood termite. The results from both methods are integrated and analyzed using the RepeatModeler software to construct a transposable element sequence database. The RepeatClassifier software is used to classify the transposable elements. The sequence variation rate of transposable elements in both termite genomes is calculated to reveal potential mechanisms of genome expansion.

3. Metabolic Pathway

Reconstruction Based on the genome annotation information of the restriction-free dechlorinating bacterium (PER-K23), the biosynthesis of quinoline-like compounds is predicted to involve four metabolic pathways.

4. Gene Evolution Analysis

Using the gene sequences of 117 single-copy orthologous proteins, a maximum likelihood species phylogenetic tree is constructed for the strains of Mollicutes, Haloplasma, and Firmicutes. This analysis reveals the acquisition and loss of the mreB and fib genes in the genomes of different bacterial strains.
