Genome size as a marker for identifying the invasive alien taxa in Fallopia section Reynoutria

Abstract

The results indicate that the amount of nuclear DNA can be used as a reliable marker for the identification of homoploid knotweed species and their hybrids. Different evolutionary pathways for the origin of high polyploids and/or hybridogenous taxa are proposed based on genome size.
