Single-Nucleotide Polymorphism Genotyping in Mapping Populations via Genomic Reduction and Next-Generation Sequencing: Proof of Concept
We report the results of a proof-of-concept experiment that validates the use of multiplex identifier (MID) barcodes and next-generation sequencing (454-pyrosequencing and Illumina GAIIe) to simultaneously discover and genotype single nucleotide polymorphisms (SNPs) from mapping populations using po...

We report the results of a proof-of-concept experiment that validates the use of multiplex identifier (MID) barcodes and next-generation sequencing (454-pyrosequencing and Illumina GAIIe) to simultaneously discover and genotype single nucleotide polymorphisms (SNPs) from mapping populations using pooled genomic reduction libraries. The genomic reduction library utilized here consisted of 60 individuals from an (L.) Heynh. mapping population. A total of 1720 and 504 SNPs were de novo identified and genotyped across the mapping population using only bioinformatic analyses of the progeny sequence fragments from the 454-pyrosequencing and Illumina datasets, respectively.
