Restriction Site Associated DNA Sequencing Technology Service

Restriction Site Associated DNA Sequencing Technology Service

Reduced-representation sequencing is a sequencing technique developed based on second-generation sequencing that uses enzymatic cleavage, sequence capture microarray technology, or other experimental means to reduce the complexity of a species' genome and sequence-specific regions of the genome to reflect partial genomic sequence-structure information. They can be divided into Complexity reduction of polymorphic sequences (CRoPS), Restriction-site associated DNA (RAD) sequencing, and Genotyping by sequencing (GBS).

The most widely used technology is RAD-seq, which uses restriction endonucleases to cleave the genome, generate fragments of a certain size, construct sequencing libraries, and perform high-throughput sequencing of the RAD markers generated after cleavage. Since RAD markers are genome-wide DNA tags presenting small fragments near specific digestion sites, representing the sequence characteristics of the whole genome, thousands of single nucleotide polymorphic markers can be obtained in most organisms by sequencing RAD markers.

  • Technical Characteristics
    • High throughput, 10 times more RAD markers can be developed in a single sequencing than traditional molecular marker development techniques.
    • High accuracy, digital signal, and high coverage make it much more accurate than traditional molecular markers.
    • High data utilization and cost-effectiveness, especially at the population level because the complexity of the genome is greatly reduced, thus reducing the cost of sequencing.
    • Short experimental cycle time, due to the high throughput characteristics, tens of thousands of markers can be generated after a single sequencing, greatly reducing the development cycle of traditional markers.
    • Large-scale screening of SNP loci can be performed even in species without a reference genome, regardless of genome sequence constraints.

  • Applications
  • RAD sequencing based on RAD markers is a technology that can be applied in both model and non-model organisms. This means that RAD can be used in many botanical research directions. For example, to identify specific target genes from extended genomes, to establish complete genetic linkage maps of the model or non-model organisms, to perform high-density genetic mapping, and to localize the genomes of unknown species.
