Metapopulation structure and fine-scaled genetic structuring in crop-wild hybrid weed beetsJ F Arnaud
Laboratoire de Genetique et Evolution des Populations Vegetales, FRE CNRS 3268, Bâtiment SN2, Université des Sciences et Technologies de Lille Lille 1, Villeneuve d Ascq Cedex, France
Heredity (Edinb) 107:395-404. 2011..Our results highlight the need to carefully depict genetic discontinuities in weed species, when attempting to describe their local genetic neighborhoods within which genetic drift and selective processes occur...
Fine-scale geographical structure of genetic diversity in inland wild beet populationsJean François Arnaud
Laboratoire de Genetique et Evolution des Populations Vegetales, UMR CNRS 8016, Bâtiment SN2, Université des Sciences et Technologies de Lille Lille 1, F 59655 Villeneuve d Ascq Cedex, France
Mol Ecol 18:3201-15. 2009....
Evidence for gene flow via seed dispersal from crop to wild relatives in Beta vulgaris (Chenopodiaceae): consequences for the release of genetically modified crop species with weedy lineagesJ F Arnaud
UMR CNRS 8016, Laboratoire de Genetique et Evolution des Populations Vegetales, Bâtiment SN2, Universitéde Lille 1, 59655 Villeneuve d Ascq cedex, France
Proc Biol Sci 270:1565-71. 2003....
Population genetic structure in a human-disturbed environment: a case study in the land snail Helix aspersa (Gastropoda: Pulmonata)J F Arnaud
UPRESA CNRS 8016, Laboratoire de Genetique et Evolution des Populations Vegetales, Bat SN2, Universite de Lille 1, 59655 Villeneuve d Ascq cedex, France
Heredity (Edinb) 90:451-8. 2003..Overall, genetic drift, along with occasional long-distance episodes of gene flow, was presumably the most likely evolutionary force that shaped the observed pattern of genetic variation...
Emergence of gynodioecy in wild beet (Beta vulgaris ssp. maritima L.): a genealogical approach using chloroplastic nucleotide sequencesStephane Fenart
Laboratoire de Genetique et Evolution des Populations Vegetales, Universite des Sciences et Technologies de Lille, UMR CNRS 8016, Bâtiment SN2, 59655 Villeneuve d Ascq cedex, France
Proc Biol Sci 273:1391-8. 2006..The emergence of gynodioecy in wild beet is confronted with theoretical expectations, describing either gynodioecy dynamics as the maintenance of CMS factors through balancing selection or as a constant turnover of new CMSs...
Effects of fine-scale genetic structure on male mating success in gynodioecious Beta vulgaris ssp. maritimaIsabelle De Cauwer
Laboratoire de Genetique et Evolution des Populations Vegetales, UMR CNRS 8016, Bâtiment SN2, Université des Sciences et Technologies de Lille Lille 1, F 59655 Villeneuve d Ascq Cedex, France
Mol Ecol 19:1540-58. 2010....
Spatial analysis of nuclear and cytoplasmic DNA diversity in wild sea beet (Beta vulgaris ssp. maritima) populations: do marine currents shape the genetic structure?Virgil Fievet
UMR CNRS 8016, FR 1818, Laboratoire de Genetique et Evolution des Populations Vegetales, Universite de Lille 1, Bâtiment SN2, 59655 Villeneuve d Ascq cedex, France
Mol Ecol 16:1847-64. 2007..This suggests the occurrence of long-distance seed dispersal events and an asymmetrical gene flow separating the eastern and western part of the Anglo-Norman gulf...
Nuclear and cytoplasmic genetic diversity in weed beet and sugar beet accessions compared to wild relatives: new insights into the genetic relationships within the Beta vulgaris complex speciesStephane Fenart
Laboratoire de Genetique et Evolution des Populations Vegetales, UMR CNRS 8016, Universite des Sciences et Technologies de Lille, Lille 1, Bâtiment SN2, 59655 Villeneuve d Ascq cedex, France
Theor Appl Genet 116:1063-77. 2008....
Long distance pollen-mediated gene flow at a landscape level: the weed beet as a case studyStephane Fenart
Laboratoire de Genetique et Evolution des Populations Vegetales, UMR CNRS 8016, FR CNRS 1818, Bâtiment SN2, Université des Sciences et Technologies de Lille Lille 1, F 59655 Villeneuve d Ascq Cedex, France
Mol Ecol 16:3801-13. 2007..Hence, it appears evident that interfield pollen-mediated gene flow between weed beets is almost unavoidable and could contribute to the diffusion of (trans)genes in the agricultural landscape...
Sex ratio variation among gynodioecious populations of sea beet: can it be explained by negative frequency-dependent selection?Mathilde Dufay
Laboratoire de Genetique et Evolution des Populations Vegetales, UMR CNRS 8016, Universite des Sciences et Technologies de Lille Lille1, F 59655 Villeneuve d Ascq Cedex, France
Evolution 63:1483-97. 2009..The large variation of sex ratio in Beta vulgaris could thus be explained by frequency-dependent selection acting on CMS genes and restorer alleles...
Variation in pollen production and pollen viability in natural populations of gynodioecious Beta vulgaris ssp. maritima: evidence for a cost of restoration of male function?M Dufay
Laboratoire de Génétique et Evolution des Population Végétales, UMR CNRS 8016, Université des Sciences et Technologies de Lille Lille 1, Villeneuve d Ascq Cedex, France
J Evol Biol 21:202-12. 2008..Finally, we discuss the consequences of these results for pollen flow and the dynamics of gynodioecy...
Spatial structure of shell polychromatism in populations of Cepaea nemoralis: new techniques for an old debateA Bellido
UMR CNRS 6553, Equipe Evolution des populations et des aspèces Service d Ecologie du sol et de Biologie des Populations, Station Biologique de Paimpont, 35380 Plélan le Grand, France
Heredity (Edinb) 88:75-82. 2002..After removing environmental effects, a significant spatial structure still remains but was essentially caused by random processes. We argue for the importance of these last phenomena...
