The development of eight microsatellite loci in the wild daffodil Narcissus triandrus (Amaryllidaceae) / Kathryn A. Hodgins in Molecular Ecology Notes, vol. 7 (2007)

Public [article]  inMolecular Ecology Notes > vol. 7 (2007) . - pp. 510-512 Titre : The development of eight microsatellite loci in the wild daffodil Narcissus triandrus (Amaryllidaceae) Type de document : Livre Auteurs : Kathryn A.

From enriched libraries, we identified 58 unique microsatellite loci. We designed primer pairs for 27 of these loci and screened genomic DNA from 38 to 40 adults from a single population. For eight polymorphic loci, the number of alleles per locus ranged from five to 17. As six primers also amplified loci in three other Narcissus species, including two horticultural varieties, we expect that some of these markers will be transferable to other Narcissus species."

Elm clone identification and the conundrum of the slow spread of Dutch Elm Disease on the Isle of Man / M. Coleman in New Journal of botany, vol. 6, n°2-3 (Année 2016)

Public [article]  inNew Journal of botany > vol. 6, n°2-3 (Année 2016) . - pp. 79-89 Titre : Elm clone identification and the conundrum of the slow spread of Dutch Elm Disease on the Isle of Man Type de document : Livre Auteurs : M. Coleman, Auteur ; S.W. A'Hara, Auteur ; P.R. Tomlinson, Auteur ; P.J. Davey, Auteur Année de publication : 2016 Article en page(s) : pp. 79-89 Langues : Anglais Catégories : [Espèces (in biblio)] Ulmaceae [Espèces (in biblio)] Ulmus Mots-clés : génétique  microsatellite Résumé : "This study was undertaken as part of a review of Ulmus L. for the forthcoming Flora of the Isle of Man. We have adopted molecular and morphological methods to reassess the identity of Ulmus on the Isle of Man and to explore the possibility that past records of English Elm, a single genotype cultivar called U. minor ‘Atinia’, were misidentifications. First, we utilised seven DNA microsatellite markers to test clone identity in a collection of 23 elms from across the Isle of Man. Sixteen samples were matched to a reference sample of Dutch Elm, U. × hollandica ‘Major’, and one sample was matched to a reference sample of English Elm. In parallel, we appraised a method employed to identify English Elm using a leaf shape metric, and found that leaf width divided by length values > 0.69 are indicative of this clone. Both molecular and morphological results in this study highlight that Dutch Elm has been misidentified as English Elm in the past, and that English Elm may in fact be a rare occurrence on the Island. The susceptibility of U. × hollandica ‘Major’ to Dutch Elm Disease suggests that the unusually slow spread of the disease on the Island is unlikely to be the result of local disease resistance in the elm population. One possibility that we explore is that the Scolytus beetle vector may experience suboptimal climatic conditions that could be limiting its dispersal, thereby reducing the rate of spread of infection."

Genetic consequences of long-term isolation for the last French population of Eryngium viviparum (Apiaceae) / Pauline Rascle in Botanical Journal of the Linnean Society, vol. 191, n°8 (Année 2019)

Public [article]  inBotanical Journal of the Linnean Society > vol. 191, n°8 (Année 2019) . - pp. 285-298 Titre : Genetic consequences of long-term isolation for the last French population of Eryngium viviparum (Apiaceae) Type de document : Livre Auteurs : Pauline Rascle, Auteur ; Elodie Flaven, Auteur ; Frédéric Bioret, Auteur ; Sylvie Magnanon, Auteur ; Erwan Glemarec, Auteur ; Sébastien Gallet, Auteur ; Eric Imbert, Auteur Année de publication : 2019 Article en page(s) : pp. 285-298 Langues : Anglais Catégories : [Espèces (in biblio)] Eryngium viviparum Mots-clés : conservation génétique  plante menacée  microsatellite Résumé : "Eryngium viviparum (Apiaceae) is an endangered endemic plant of the Atlantic region of Europe, growing in seasonally flooded sites, and is characterized by a highly disjunct distribution. It occurs in just a few sites in the north-western part of the Iberian Peninsula and in a single locality in France. To improve the conservation status of E. viviparum in France, a conservation programme has been implemented to reintroduce the species. Before considering such an operation, genetic studies were conducted to determine the genetic status of the last French population and to identify the genetic source that should be considered for the best reintroduction strategy. Using microsatellite markers, we documented the genetic structure of the last French population and compared its genetic diversity with that of ten Iberian populations, which cover the three geographical regions where the species occurs. As expected, the French population of E. viviparum shows low genetic diversity due to a bottleneck and geographical isolation. The evolutionary potential appears low, with no private alleles in this population. Furthermore, this population is highly differentiated from the Iberian populations in terms of genetic variation and ecological niche. These results bring new questions regarding the conservation of E. viviparum in France, especially for management and reintroduction aimed at favouring genetic diversity and avoiding extinction."

Natural selection on floral traits through male and female function in wild populations of the heterostylous daffodil Narcissus triandrus / Kathryn A. Hodgins in Evolution, vol. 62, fasc. 7 (2008) 

Public [article]  inEvolution > vol. 62, fasc. 7 (2008) . - pp. 1751-1763 Titre : Natural selection on floral traits through male and female function in wild populations of the heterostylous daffodil Narcissus triandrus Type de document : Livre Auteurs : Kathryn A. Hodgins, Auteur ; Spencer Barrett, Auteur Année de publication : 2008 Article en page(s) : pp. 1751-1763 Langues : Anglais Catégories : [Espèces (in biblio)] Narcissus triandrus [Thèmes] Reproduction Mots-clés : microsatellite  trait floral Résumé : "Measurements of natural selection in hermaphrodite populations require the analysis of performance through both female and male sex functions. Here, we investigate selection on three floral traits: flower number, flower length, and corona width through both sex functions in natural populations of the tristylous daffodil Narcissus triandrus. Selection through female function was examined in six populations, and in two of these we also estimated male selection gradients using multilocus microsatellite genotyping of parents and offspring. We detected significant directional selection for flower number through female function, and significant stabilizing selection for corona width and flower length through male function. Variation in male reproductive success was strongly influenced by the distance between mates and was significantly higher than variation in female reproductive success in one population, a result consistent with Bateman's principle. However, variation through both sex functions was similar in the other population and there was a significant negative correlation between female and male fitness indicating sex‐specific trade‐offs in reproductive success. Selection on floral design in N. triandrus was stronger through male than female function probably because floral morphology plays an important role in promoting effective cross‐pollen transfer in populations of this heterostylous species."

In France, the first one is rare and endangered, whereas the second is common. To compare their population genetic structure, seven polymorphic microsatellite markers were characterized. We found no polymorphism in R. nodiflorus, whereas R. flammula was polymorphic at each locus. The total number of alleles per locus varied from three to eight. Observed heterozygosities ranged from 0 to 0.261. This set of microsatellites offers an efficient tool to study population genetic structure and to compare the results between closely related endangered and common species."
