Genotyping-by-sequencing (GBS) is a method to discover and genotype simultaneous genome-wide high-throughput single nucleotide polymorphisms (SNPs). GBS is based on reducing genome complexity with restriction enzymes. Here we describe a method developed by Elshire et al. for constructing simplified GBS libraries and recent bioinformatic approaches developed to analyze the large volume of polymorphism data generated by this method. GBS approach is suitable for population studies, taxonomic and phylogenic studies, germplasm characterization, and breeding and trait mapping for a wide range of organisms, including plants with complex genomes.
