Human-mediated dispersal of weed species during the Holocene: A case study of Chenopodium album agg.
Original language description
We showed that the most haplotype-diverse area for the entire Chenopodium album aggregate is central Asia. Interestingly, Europe is poor in terms of haplotype diversity, showing the same level of diversity as the western Asian region. The pairwise genetic differentiation between Europe, the Mediterranean and western Asia is lower than between any of these regions and either central Asia or Siberia. This points to the origin of the European Chenopodium species pool as being in western Asia. In some phylogenetically-defined clades, species could not be distinguished based on cpDNA haplotypes due to a high level of haplotype sharing. However, in others, the haplotype variation follows the species boundaries. Using the Chenopodium album agg. species as a model, we show the importance of central Asia as one of the main centres of diversity for weedy species. However, the group’s colonisation of Europe had its origins in western Asia, highlighting the importance of human-mediated dispersal of ruderal and weed plant species accompanying the westward spread of agriculture in the Neolithic period.
