Phylogenomics and Placement of Polyploidy with Transcriptomes in Brassicaceae.

Cheaper sequencing costs due to next-generation sequencing (NGS) and corresponding computer tools have dramatically impacted the field of plant systematics. At this time, the most cost effective method for systematists allows multiplexing samples for sequencing of DNA. These resulting data provide researchers with the ability to obtain multiple perspectives on the evolutionary relationships among plants from three organellar genomes: the plastid (or chloroplast), mitochondrial, and nuclear genome. However, due to the lack of reads coming from nuclear genomes, it remains difficult to resolve relationships without more expensive, deep sequencing or targeted sequence capture. Here we show how transcriptomics can be leveraged for the identification of single copy nuclear genes, useful for phylogenomic inference.
