Abstract

Due to complex history of European forests, natural populations may not necessarily represent autochthonous genepools for forest trees. Eastern Prussian forests were famous for using non-local sources for afforestation. We studied efficiency of a set of nuclear microsatellite markers (nSSR) for genetic association and diversity studies of 194 adult trees from 5 populations genotyped at 11 nSSR loci. The Bayesian and UPGMA clustering revealed two genetically distinct groups: (a) the Baltic group, and (b) the Bavarian one and an over 200-years-old sea-side Lithuanian population of Juodkrante from the sea-side Curonian spit of Neringa. We interpret this result as putative introduction of Bavarian Scots pine back in the 18th century, when reforestation efforts were made to sustain moving sands in the dunes of Neringa. The genomic SSRs were more variable than the EST SSRs. However, the association between the variability of the nuclear microsatellite loci and their efficiency in detecting population differentiation was not strong. Keywords: nSSR, Pinus sylvestris (L.), population structure, provenance transfer, FRM transfer, molecular markers

DNA标记揭示了海边立陶宛和巴伐利亚苏格兰松种群之间的遗传联系

由于欧洲森林的复杂历史，自然种群不一定代表森林树木的原生基因库。东普鲁士的森林以利用外来资源造林而闻名。利用核微卫星标记(nSSR)对5个群体194棵成树11个基因型位点的遗传关联和多样性进行了研究。贝叶斯聚类和UPGMA聚类揭示了两个遗传上截然不同的群体:(a) 波罗的海群体，(b) 巴伐利亚群体和来自尼林加海边库尔斯口的200多年前的Juodkrante海边立陶宛人群。我们将这一结果解释为18世纪巴伐利亚苏格兰松的引入，当时人们进行了重新造林，以维持尼林加沙丘中的流动沙子。基因组SSRs比EST SSRs更具变异性。然而，核微卫星基因座的变异率与其检测群体分化的效率之间的相关性并不强。关键词:nSSR，松，种群结构，种源转移，FRM转移，分子标记

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
