Sažetak
Comparative cytological analyses combined with phylogeny have been applied in three closely related genera Anemone, Hepatica and Pulsatilla in order to decipher aspects of their evolutionary differentiation. Heterochromatin distribution as well as 35S and 5S rDNA localization is determined for the first time in eleven Anemone and three Pulsatilla species. The mechanisms involved in karyotype evolution are identified and interpreted in a phylogenetic context established from combined ITS of the 35S and NTS of the 5S rDNA trees. Investigated Anemone species exhibited great variations in position of heterochromatin and in number and position of 5S and 35S rDNA. One to three 35S and one to three 5S rDNA loci were present in investigated taxa. 35S rDNA loci are positioned on the short arm of acrocentric chromosomes, while for 5S rDNA loci there is no preferential chromosomal position. The cytogenetic data obtained in this study are supported by the molecular data ; species within the same clade of the ITS and NTS phylogeny have the similar heterochromatin banding pattern as well as number and distribution of rDNA loci. Results of this study generally agree with present classification of Anemoninae and support the hypothesis of the Mediterranean centre of origin of Anemone.
