Preliminarno istraživanje porijekla vrste Hypericum perforatum L

Hypericum perforatum L. is considered as a hybrid species. Potential ancient hybridisation occurred in North – East Asia between european species H. maculatum Crantz. and asian species H. attenuatum Choisy on the overlaping zone of their distributions. The aim of the present study was to determine whether hybrid origin of Hypericum perforatum L. could be detected using restriction analysis of cpDNA. Three species was compared on the basis of restriction patterns of two non-coding regions within a large single copy of chloroplast genome. Out of the seven restriction patterns H. perforatum L. differs in all of them, while potential parents species H. attenuatum Choisy and H. maculatum Crantz. are identical. The obtained results indicate high degree of rearrangements in compered parts of cpDNA molecule during speciation of H. perforatum L. Restriction analysis of other chloroplast genome region or sequencing should provide better comperison of these three species and evidence of parental species.
