Unraveling Genetic Diversity Amongst European Hazelnut (Corylus avellana L.) Varieties in Turkey..
European hazelnut ( ) is a diploid (2n = 22), monecious and wind-pollinated species, extensively cultivated for its nuts. Turkey is the world-leading producer of hazelnut, supplying 70–80% of the world’s export capacity. Hazelnut is mostly grown in the Black Sea Region, and maintained largely through clonal propagation. Understanding the...Oztolan-Erol, Nihal ; Helmstetter, Andrew J. ; İnan, Asuman ; Buggs, Richard J. A. ; Lucas, Stuart J.

Evidence for the Widespread Occurrence of Bacteria Implicated in Acute Oak Decline from Incidental Genetic Sampling.
Acute Oak Decline (AOD) is complex syndrome affecting Britain’s keystone native oak species, (Quercus robur L. and Q. petraea L. (Matt.) Liebl.), in some cases causing mortality within five years of symptom development. The most distinguishable symptom is weeping stem lesions, from which four species of bacteria have been isolated:... -

Introgression between Betula tianshanica and Betula microphylla and its implications for conservation
In areas where closely related species meet, the possibility that they may hybridize must be taken into account by conservationists. Hybridization may have positive or negative consequences for the long‐term future of species. If present, its dynamics need to be understood. Betula microphylla is a declining wetland tree species in... -

Repeated long-distance dispersal and convergent evolution in hazel
Closely related species with a worldwide distribution provide an opportunity to understand evolutionary and biogeographic processes at a global scale. Hazel (Corylus) is an economically important genus of tree and shrub species found in temperate regions of Asia, North America and Europe. Here we use multiple nuclear and chloroplast loci...Helmstetter, Andrew J. ; Buggs, Richard J. A. ; Lucas, Stuart J.
