Leaf allozyme variation in cultivated and wild olive trees (Olea europaea L. )
Article Abstract:
The genetic modifications undergone by the olive tree as a result of very long-term empirical domestication was assessed by comparing the allozyme variations in cultivated and wild species. Genetic analyses showed that nine out of 11 loci studied were polymorphic with a mean of 2.7 alleles per locus. Cultivated trees had 19% heterozygous loci while wild trees had 66% heterozygous loci. Furthermore, results showed that the olive tree, Olea europea, showed a high level of enzyme polymorphism with novel genotype combinations in wild species.

Endemic North African quercus afares Pomel originates from hybridisation between two genetically very distant oak species (Q.suber L. and Q.canariensis wild.): evidence from nuclear and cytoplasmic markers
Article Abstract:
Quercus afares, an endemic North African species that combines morphological, physiological and ecological traits ecological traits of both Quercus suber and Quercus canariensis, two distant species is presented. Two Quercus afares populations of both Quercus suber nad Quercus canariensis sampled both within and outside areas where these species overlap with Quercus afares is studied.

Allozyme variation of oleaster populations (wild olive tree) (olea europaea L.) in the Mediterranean basin
Article Abstract:
Allozyme variation was analyzed at 10 loci in 31 large and 44 small oleaster populations in various habitats of the Mediterranean Basin and the Canary Islands. Intensive selection involving inbreeding took place under cultivation to obtain particular characteristics in the olive cultivars.
