Abstract: 
Pinus nigra J.F. Arnold, European black pine, is a typical component of Mediterranean and subMediterranean coniferous forests with highly fragmentary distribution. Western Mediterranean
populations of this species have been studied genetically to date, while eastern populations from
the central Balkans, which are larger and more abundant, are still genetically understudied. We
analyzed seven populations of P. nigra representing all infraspecific taxa recognized within
the central Balkans (subspecies nigra with varieties nigra and gocensis Đorđević; and subspecies pallasiana (Lamb.) Holmboe with varieties pallasiana and banatica (Endl.) Georgescu et
Ionescu), with three chloroplast microsatellites (cpDNA SSRs) and one mitochondrial (mtDNA)
locus.Although our molecular data failed to support circumscription of studied infraspecific taxa,
we found that genetic patterns at both genomes are in accordance with those found previously
in westward populations of this species, that is – exceptionally high levels of genetic diversity
(HT=0.949) and low genetic differentiation (GST=0.024) at the cpDNA level, and moderate
levels of genetic diversity (HT=0.357) and genetic differentiation (GST=0.358) at the mtDNA
level. Based on genealogical relations of mtDNA types currently present in Balkans’ and Iberian/
African populations, we inferred that the ancestral gene pool of P. nigra already harbored polymorphism at position 328 prior to the divergence to two lineages currently present in westward
and eastward parts of the species range distribution. Subsequent occurrence of three mutations,
which distinguish these two lineages, suggests their long-term isolation
