Multilocus genomic associations among selected taxa of genus Potentilla (Rosaceae) in Poland using RAPD analysis

Abstract

Nine taxa of Potentilla species from Poland representing P. sect. Terminales (DÅ‘ll.) Gren et Godr. and P. sect. Aureae (Wolf) Juz. were analyzed via a series of RAPD (random amplified polymorphic DNA) to tests (1) the hypotheses that the six species representing P. subsect. Collinae Juz. of section P. Terminales, i.e. P. collina Wibel, P. thyrsiflora Zimmeter, P. wimannania Günther et Schummel, P. leucopolitana P. J. Müll., P. leucopolitana P. J. Müll. ´ P. incana P. Gertner, B. Meyer et Scherb, P. koernickei Zimmeter, are genetically differentiated enough to be considered as a separate taxa, and (2) the position of populations of P. thyrsiflora and P. collina with respect to section Terminales (P. argentea L) and section Aureae (P. tabernaemontani Ascherson and P. incana P. Gaertner, B. Meyer et Scherb.). The clustering of RAPD-based genetic similarity values using the UPGMA method resulted in the dendrogram shown that exist incompletely accordance among RAPD and morphological variation. According to ‘overgenomic’ associations based on a series of selected at random genomic loci, P. thyrsiflora and P. collina are closely related and similarly related to the species: P. argentea, P. tabernaemontani and P. incana hypothesized as being their ‘parental’. Within section Terminales, our dendrogram shows P. argentea to be relatively isolated from the other members of the section analysed, P. thyrsiflora and P. collina.
