No Evidence of Geographical Structure of Salicinoid Chemotypes within Populus Tremula
Salicinoids are well-known defense compounds in salicaceous trees and careful screening at the population level is warranted to fully understand their diversity and function. European aspen, Populus tremula, is a foundation species in Eurasia and highly polymorphic in Sweden. We exhaustively surveyed 102 replicated genotypes from the Swedish Aspen collection (SwAsp) for foliar salicinoids using...
متن کامل20-(Z)-Cinnamoylsalicortin: A novel salicinoid isolated from Populus tremula
Using a combination of NMR and mass spectroscopic techniques, we have isolated a new salicinoid from the foliage of European aspen (Populus tremula) and identified it as 20-(Z)-cinnamoylsalicortin. The relatively high amounts in foliage and the similarity in structure to bioactive salicinoids isolated from other salicaceous trees indicates that this compound may have implications for the study ...
متن کاملRunning 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 کاملRunning title: Association mapping in Populus tremula Nucleotide polymorphism and phenotypic associa- tions within and around the phytochrome B2 locus in European aspen (Populus tremula, Salicaceae)
We investigated the utility of association mapping to dissect the genetic basis of naturally occurring variation in bud phenology in European aspen (Populus tremula). With this aim, we surveyed nucleotide polymorphism in 13 fragments spanning an 80 kb region surrounding the phytochromeB2 locus. Although polymorphism varies substantially across the phyB2 region, we detected no signs for deviatio...
