The use of next-generation sequencing (NGS) technologies for genotyping by sequencing (GBS) is becoming an increasingly important, cost-effective, and unique tool.  NGS is useful for association studies and genomics-assisted breeding in a range of plant and animal species, including those with complex genomes that lack a reference sequence. It can be used for the discovery and identification of SNPs or to screen large panels of known markers.

The Ion Proton™ and Ion PGM™ Sequencers enable plant and animal researchers to use flexible, high-throughput GBS to perform fast and cost-effective studies.

GBS: advantages of the Ion Proton™ and Ion PGM™ Sequencers
  • Allow both SNP marker confirmation and de novo marker (SNP) discovery, even in cases where there is no reference genome
  • Provide attractive, low-cost options for large numbers of samples and data points
  • Utilize highly multiplexed sequencing to scale from thousands to millions of data points per day
  • Enable 2–4 hour sequencing turnaround times to facilitate efficient planning for the next reproduction cycle
  • Deliver a high degree of accuracy of SNP calling
  • Offer versatility for many applications: de novo and targeted resequencing, transcriptome sequencing, and more

Ion PGM™
Multiplex enrichment PCR

In cases where a set of SNPs has been defined for a section of the genome, this approach uses PCR primers designed to amplify the targets of interest. View our complete solution for multiplex PCR below. Creating and ordering custom panels is easy with the Ion AmpliSeq™ Designer: a free, online assay design tool that enables custom design for any genome. Use the preloaded bovine, chicken, pig, and sheep genomes to design your custom panel, or easily upload a FASTA file with your desired reference sequences for your genome of interest.
