A next-generation sequencing method for overcoming the multiple gene copy problem in polyploid phylogenetics,applied to <Emphasis Type="Italic">Poa</Emphasis> grasses

Background  

Polyploidy is important from a phylogenetic perspective because of its immense past impact on evolution and its potential future impact on diversification, survival and adaptation, especially in plants. Molecular population genetics studies of polyploid organisms have been difficult because of problems in sequencing multiple-copy nuclear genes using Sanger sequencing. This paper describes a method for sequencing a barcoded mixture of targeted gene regions using next-generation sequencing methods to overcome these problems.
