SNP discovery by exome capture and resequencing in a pea genetic resource collection

Abstract

Pea is a major pulse crop in temperate regions and a model plant in genetics. Large genetic marker resources are needed to assess the genetic diversity in the species genepool and to provide selection tools for breeders. In this study, we used second-generation sequencing to perform an exome-capture protocol using a diverse pea germplasm collection, and produced a resource of over 2 million Single Nucleotide Polymorphisms. This dataset was then used to characterize the genetic diversity present in the panel and compute phylogenetic and structure analyses. The development of this resource paves the way for Genome-wide association studies and the development of powerful genotyping tools.
