Genetic differentiation of oak populations within the Quercus robur/Quercus petraea complex in Central and Eastern Europe

Heredity (Edinb). 2001 May;86(Pt 5):557-63. doi: 10.1046/j.1365-2540.2001.00874.x.


Genetic structure of 25 indigenous populations of sessile and pedunculate oaks (Quercus petraea and Q. robur), originating from three geographical regions: Slovakia, Bulgaria and the Republic Mari-El (Russia), was investigated using isozyme markers. Mean number of alleles per locus ranged between 1.8 and 2.6 in Q. robur populations and from 2.0 to 3.0 in Q. petraea populations; slightly higher expected heterozygosity values were found in Q. robur compared to Q. petraea. One locus, coding for a substrate-nonspecific dehydrogenase, differentiated the two species. The interspecific component of gene diversity was 46.7% at this locus, compared to 0.4-7.8% at the remaining loci.
