Animal/Plant Whole Genome De Novo Sequencing

Cow-bred for meat, skin and milk.

Plant and animal de novo sequencing refers to the sequencing of a new genome by bioinformatics analysis without any reference sequence, which is aligned, spliced, and assembled to generate the initial genome sequence of a specific organism. Through this method, the whole genome sequences of plants and animals can be obtained, and then a series of studies such as functional gene mining, regulatory metabolic network construction, and species evolution analysis can be carried out downstream of the species to advance the research of the species. Based on the features of long read length, no GC preference, and high sequencing accuracy, CD Genomics can help our customers decipher most of the structural properties of the genome using long-read technologies.

Advantages of De Novo Sequencing with Long-Read Technologies

-PacBio SMRT Sequencing

PacBio SMRT Sequencing technology has two sequencing modes, including continuous long read (CLR) and circular consensus sequencing (CCS). Among them, CCS can generate High-fidelity (HiFi) reads, the latest data type developed by PacBio with long reads and high accuracy. As a result, PacBio HiFi reads can greatly enhance the accuracy of genome assembly, even for the most complex genomes.

-Oxford Nanopore Sequencing

Nanopore sequencing differs from other sequencing platforms in that the nucleotides are read directly, eliminating the need for a DNA synthesis process. Moreover, the nanopore sequencing platform itself has no significant technical limitations on DNA read length. Ultra-long read lengths (ULR, N50=100-200Kb, one of the data types generated by nanopore sequencing) can be utilized for high-quality genome assembly.

Application of Animal/Plant Whole Genome De Novo Sequencing

  • Building species databases.
  • Study of the evolutionary origin of species, trait characteristics.
  • Mining functional genes.
  • Laying the foundation for subsequent resequencing to discover single nucleotide polymorphisms (SNPs) and other genetic variants.

Long-read technologies combined with other complementary technologies have become the technology of choice for plant and animal genome assembly.
