True identity of the european freshwater Ulva (Chlorophyta, Ulvophyceae) revealed by a combined molecular and morphological approach
Original language description
A set of 18 freshwater and morphologically similar marine samples of Ulva were collected from inland and coastal waters throughout Europe to assess their taxonomic identity and invasive potential. An additional 11 specimens were obtained from herbaria. The material was studied using a combination of classical morphological methods and molecular techniques; the latter included sequencing of the nuclear internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2) and the chloroplast RUBISCO LSU (rbcL) gene and comparison of the ITS2 secondary structure predictions. Based on classical methods, all the specimens could be determined as U. flexuosa Wulfen and could be further divided into three groups matching three infra-specific taxa. This pattern was generally well supported by molecular phylogenetic analyses. All sequenced samples formed a monophyletic lineage within Ulva, showing a putative synapomorphy in the ITS2 secondary structure. The individual subspecies corresponded to phylogenetic
