At the species level, understanding of biodiversity basically needs investigations on intraspecific genetic variation. The present study is on polymorphic plastid DNA which was confirmed to be predominantly paternally inherited in fir (Abies. spec). Two highly polymorphic chloroplast microsatellite loci exhibit distinct geographic patterns of genetic variation in Abies alba. Reconstruction of glacial refugia and genetic erosion is inferred from the patterns. Furthermore, potential of the marker for paternity analysis and for tracing pollen dispersal is presented and discussed.
