Running title: Multi-locus polymorphism in Populus tremula Keywords: demography, linkage disequilibrium, nucleotide polymorphism, Populus tremula Multilocus patterns of nucleotide polymorphism and the demographic history of Populus tremula
I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high frequency derived mutations at silent sites, relative to neutral e...

متن کاملMolecular population genetics of inducible defense genes in Populus tremula
Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred. Herbivores, on the other hand, respond to these plant defenses by evolving counte...
متن کاملEfficient Agrobacterium-Mediated Transformation of Hybrid Poplar Populus davidiana Dode × Populus bollena Lauche
Poplar is a model organism for high in vitro regeneration in woody plants. We have chosen a hybrid poplar Populus davidiana Dode x Populus bollena Lauche. By optimizing the Murashige and Skoog medium with (0.3 mg/L) 6-benzylaminopurine and (0.08 mg/L) naphthaleneacetic acid, we have achieved the highest frequency (90%) for shoot regeneration from poplar leaves. It was also important to improve ...
متن کامل[Sexual differences in climatic response of dioecious Populus davidiana tree].
The tree-ring width series and standardized chronologies of Populus davidiana trees in broad-leaved and Korean pine forest in Changbai Mountains were developed separately for male and female trees. Their differential radial growth and their relationship with climatic conditions were analyzed to reveal the effect of gender on radial growth and their climatic responses. It was found that there wa...
