I’m a leading author of an article about the phylogenetic position of seven poorly known species of Ferula published in Systematics and Biodiversity. We also tested in this study the phylogenetic utility of several chloroplast intergenic spacers (trnH-psbA, trnS-trnG, and atpB-rbcL) for tree reconstruction of this highly diverse genus. We presented the most comprehensive tree of Ferula to date based on almost 150 ITS sequences available in GenBank. This large dataset made possible to recognize close relatives of the studied species. In addition, we clearly showed that the studied intergenic spacers are too conservative and having too many structural changes (e.g. indels) to be good markers for phylogenetic studies of the genus. This research was supported by the Polish National Science Centre grant UMO-2015/17/B/NZ8/02453.
