DNA barcoding approach fails to discriminate Central European bladderworts (Utricularia, Lentibulariaceae), but provides insights concerning their evolution
Original language description
The main features to distinguish the seven native Utricularia species occurring in central Europe are found in flower shape, but flowering identification is often doubtful and uncertain. A recent morphometric work highlighted that there are no univocal reliable extra-floral morphological features allowing a safe identification at species level. Therefore, DNA barcoding approach is attempted here. Molecular analyses were performed to search for DNA barcodes using nuclear ITS (rDNA), plastid (cpDNA) trnL-trnF IGS and rps16 intron sequences. Generally, the barcoding approach failed to discriminate Utricularia species, although it could be of some help in the U. minor aggregate. With few exceptions, U. bremii shows peculiar DNA regions different from U. minor for both plastid markers investigated. However, interesting hypotheses could be derived from the obtained networks, including hybridization events to explain the rise of mostly sterile species, such as U. stygia. This species clusters with the other species of the U. intermedia aggregate in plastid phylogenetic graphs, while it is closely related to species of the U. minor aggregate in ITS phylogenetic graphs.
