With more than 400 species, the genus Potentilla has a wide distribution
causing morphological variations. Besides the wide distribution, many
conditions such as hybridization, introgression, autopolyploidy, and
allopolyploidy are observed in the genus. These can lead to
misidentifications and taxonomic problems. DNA barcoding studies are
important for species identification and solving taxonomic problems.
However, preferred DNA sequences may have different effects among
plant groups. Therefore, which DNA regions should be preferred is
important to obtain more comprehensive results. In this research, psbAtrnH IGS sequences belonging to the Potentilla taxa were examined
based on their compatibility and analyzed variable sites, passim-info
sites, and nucleotide frequencies (%) for the region relevant by using
Molecular Evolutionary Genetics Analysis (MEGA 11). Finally, a
Maximum Parsimony (MP) dendrogram was performed to evaluate the
Potentilla taxa taxonomically and phylogenetically. As a result of this
study, it can be stated that the taxa belonging to the genus Potentilla
were well grouped in the dendrogram and the use of psbA-trnH IGS
sequences is strongly recommended for further studies.
