Specific-Locus Amplified Fragment Sequencing (SLAF-Seq) as High-Throughput SNP Genotyping Methods.

Most plant agronomic traits are quantitatively inherited. Identification of quantitative trait loci (QTL) is a challenging target for most scientists and crop breeders as large-scale genotyping is difficult. Molecular marker technology has continuously evolved from hybridization-based technology to PCR-based technology, and finally, sequencing-based high-throughput single-nucleotide polymorphisms (SNPs). High-throughput sequencing technologies can provide strategies for sequence-based SNP genotyping. Here we describe the SLAF-seq that can be applied as the SNP genotyping approach. The high-throughput SNP genotyping methods will prove useful for the construction of high-density genetic maps and identification of QTLs for their deployment in plant breeding and facilitate genome-wide selection (GWS) and genome-wide association studies (GWAS).
