These studies have been limited, however, by the use of few accessions per polyploid species and by low taxonomic resolution, providing clade-specific, but not species-specific origins within clades.

Twenty papers in the special issue of the American Journal of Botany explore the evolutionary importance of polyploidy. Crepis was among the first plant genera studied using biosystematic approaches, and the landmark monograph by Babcock and Stebbins (1938) established the genus as a model for research on asexual polyploids.

The resurgence in polyploidy research has followed the surprising result that many plant genomes are actually ancient polyploidy events.
The American Journal of Botany Special Issue on "The Evolutionary Importance of Polyploidy" explores the latest developments and research in the field. Michael Barker (University of Arizona), along with Drs. Chris Pires (University of Missouri), the collection gathers contributions that began as a symposium at the Botany 2015 meetings in Alberta, Canada.
The two paralogous sequences could be differentiated by large SSR number variations and one or two additional SNPs or In Dels in every 100 bp of genic region, which can serve as a reliable identifier for each locus.
