Titre : Genetic diversity and differentiation of two Mediterranean pines (Pinus halepensis Mill. And Pinus pinaster Ait.) along a latitudinal cline using chloroplast microsatellite markers Type de document : Électronique Auteurs : A Gomez ; Giovanni Vendramin ; Santiago Gonzàlez-Martinez ; Ricardo Alia Année de publication : 2005 Article en page(s) : 257-263 Langues : Anglais (eng) Mots-clés : Pinus halepensis Mill., 1768 Pinus pinaster Aiton, 1789 Résumé : Several studies have reported glacial refugia and migration pathways for different pine species in the Iberian Peninsula, all of them based on a single-species approach. In this paper, chloroplast microsatellites (cpSSRs) are used to compare population genetic structure and diversity estimates for interspecific pairs of populations located along a cline from southwestern (latitude 36°32′ N, longitude 5°17′ W) to northeastern Spain (latitude 42°14′ N, longitude 2°47′ E) in two widely distributed Mediterranean pines, Pinus halepensis Mill. and Pinus pinaster Ait. Some cpSSRs were shared between species, facilitating comparison of levels of gene diversity at the species level and inferences about within and among species differentiation. P. pinaster showed a much higher number of variants (29) and haplotypes (69) than P. halepensis (20 and 21, respectively). Moreover, genetic diversity estimates for interspecific pairs of populations along the cline were negatively correlated. Three main causes may explain the differences between species in the present-day distribution of genetic diversity: (1) the distribution of genetic variability before the Quaternary glaciations, with an earlier presence of P. pinaster in the Iberian Peninsula and a late spread of P. halepensis from eastern and central Europe, (2) the location of the Holocene glacial refugia and the migration pathways from these refugia to the present-day range (from northeast to southwest in P. halepensis and from southwest to northeast and northwest in P. pinaster) and (3) the interactions between species during the postglacial spread.

Titre : Geography determines genetic relationships between species of mountain pine (Pinus mugo complex) in western Europe Type de document : Électronique Auteurs : Myriam Heuertz ; Jennifer Teufel ; Santiago Gonzàlez-Martinez ; Alvaro Soto ; Bruno Fady (1960-) ; Ricardo Alia ; Giovanni Vendramin Année de publication : 2009 Article en page(s) : 16 p. Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Génétique et écologie (dynamique, démographique, sélection) Mots-clés : Pinus mugo Turra, 1764 Pinus sylvestris L., 1753 Résumé : Our aims were to test whether morphological species of mountain pines were genetically supported in the western part of the distribution range of the Pinus mugo species complex (Pinus mugo Turra sensu lato), to resolve genetically homogeneous clusters of populations, to determine historical demographic processes, and to assess the potential hybridization of mountain pines with Scots pine, Pinus sylvestris L. Populations were sampled in the Iberian System, the Pyrenees, the French Mont Ventoux, Vosges and Jura mountains, the German Black Forest and throughout the Alps. This corresponded to a range-wide sampling for mountain pine sensu stricto (Pinus uncinata Ram.) and to a sampling of the western parts of the ranges of dwarf mountain pine (Pinus mugo Turra sensu stricto) and bog pine/peatbog pine [Pinus rotundata Link/Pinus × pseudopumilio (Willk.) Beck]. In total, 786 individuals of P. mugo sensu lato from 29 natural populations, and 85 individuals of P. sylvestris from four natural populations were genotyped at three chloroplast microsatellites (cpSSRs). Populations were characterized for standard genetic diversity statistics and signs of demographic expansion. Genetic structure was explored using analysis of molecular variance, differentiation statistics and Bayesian analysis of population structure (BAPS). One hundred haplotypes were identified in P. mugo sensu lato. There was a stronger differentiation between geographical regions than between morphologically identified taxa (P. mugo sensu stricto, P. uncinata and P. rotundata/p. × pseudopumilio). Overall genetic differentiation was weak (GST = 0.070) and displayed a clear phylogeographic structure [NST = 0.263, NST > NST (permuted), P < 0.001]. BAPS identified a Pyrenean and an Alpine gene pool, along with several smaller genetic clusters corresponding to peripheral populations. The core regions of the Pyrenees and Alps were probably recolonized, respectively by P. uncinata and P. uncinata/P. mugo sensu stricto, from multiple glacial refugia that were well connected by pollen flow within the mountain chains. Pinus rotundata/P. x pseudopumilio populations from the Black Forest, Vosges and Jura mountains were probably recolonized from various glacial populations that kept their genetic distinctiveness despite late glacial and early Holocene expansion. Marginal P. uncinata populations from the Iberian System are compatible with elevational shifts and long-term isolation. The causes of haplotype sharing between P. mugo sensu lato and P. sylvestris require further research Lien pérenne : DOI : 10.1111/j.1365-2699.2009.02223.x / HAL : hal-02664628

Titre : A new scenario for the Quaternary history of European beech populations: palaeobotanical evidence and genetic consequences Type de document : Imprimé Auteurs : Donatella Magri ; Giovanni Vendramin ; Bernard Comps ; Isabelle Dupanloup ; Thomas Geburek ; Dušan Gömöry (1961-) ; Malgorzata Latalowa ; Thomas Litt ; Ladislav Paule ; Joan Maria Roure ; Ioan Tantau ; W. O. van der Knaap ; Rémy Petit ; Jacques-Louis de Beaulieu (1942-) Année de publication : 2006 Article en page(s) : 199-221 Langues : Anglais (eng) Mots-clés : Fagus sylvatica L., 1753 Résumé : Here, palaeobotanical and genetic data for common beech (Fagus sylvatica) in Europe are used to evaluate the genetic consequences of long-term survival in refuge areas and postglacial spread. Four large datasets are presented, including over 400 fossil-pollen sites, 80 plant-macrofossil sites, and 450 and 600 modern beech populations for chloroplast and nuclear markers, respectively. The largely complementary palaeobotanical and genetic data indicate that: (i) beech survived the last glacial period in multiple refuge areas; (ii) the central European refugia were separated from the Mediterranean refugia; (iii) the Mediterranean refuges did not contribute to the colonization of central and northern Europe; (iv) some populations expanded considerably during the postglacial period, while others experienced only a limited expansion; (v) the mountain chains were not geographical barriers for beech but rather facilitated its diffusion; and (vi) the modern genetic diversity was shaped over multiple glacial–interglacial cycles. This scenario differs from many recent treatments of tree phylogeography in Europe that largely focus on the last ice age and the postglacial period to interpret genetic structure and argue that the southern peninsulas (Iberian, Italian and Balkan) were the main source areas for trees in central and northern Europe.
