Sažetak
Cultivation of medicinal and aromatic plants represents a sustainable approach for growing demands for large volume production and as a protection of wild populations from over harvesting. Dalmatian sage (Salvia officinalis L., Lamiaceae) is a well-known aromatic and medicinal Mediterranean plant, native in coastal region of the western Balkan and southern Apennine Peninsulas and commonly cultivated worldwide. It is widely used in food, pharmaceutical and cosmetic industries, and the knowledge of its genetic diversity and spatiotemporal patterns is important for plant breeding programs and conservation. We used eight microsatellite markers in order to investigate the genetic diversity and structure within and among 23 indigenous and seven cultivated/naturalized populations distributed on Balkan Peninsula. The results provided clear separation of the two groups and indicated the origin of cultivated material from one restricted geographical area. Most of genetic diversity in both groups was attributable to differences among individuals within populations, while spatial analysis of indigenous populations indicated that 22.50% of genetic variance resulted from isolation by distance. Geographical structuring of indigenous populations was found with clustering analysis and three subclusters of indigenous populations appeared. The highest level of gene diversity and the number of private alleles were found in the central part of the eastern Adriatic coast suggesting that these populations were a part of genetic refugia during glaciations. Decrease of gene diversity and the number of private alleles towards north-west Adriatic and southernmost and eastern Balkan Peninsula is suggestive of subsequent colonization events.
