TL;DR: The role of seed exchange networks in the preservation and adaptation of crop specific and genetic diversity is discussed in this article, where the authors advocate a diversity of approaches to foster the creation of robust and policy-relevant knowledge.
Journal ArticleDOI
Genetic diversity and spatial structure within a natural stand of a tropical forest tree species, Carapa procera (Meliaceae), in French Guiana
Agnès Doligez,Hélène Joly +1 more
TL;DR: No clear-cut spatial pattern was observed in pollen allele frequencies, which supports the hypothesis of extensive pollen flow, and the overall lack of structure is consistent with the data already available on the mating system of this predominantly outcrossing species.
Journal ArticleDOI
Fine-scale spatial genetic structure with nonuniform distribution of individuals.
TL;DR: A novel individual-based model of isolation by distance was constructed to simulate genetic evolution within nonuniformly distributed continuous plant populations and found larger values of spatial genetic autocorrelations in highly clumped populations than in uniformly distributed populations.
Journal ArticleDOI
High outcrossing rates in fields with mixed sorghum landraces: how are landraces maintained?
TL;DR: Although the biological traits of sorghum led to extensive pollen flow among landraces, selection exerted by farmers appears to be a key parameter affecting the fate of new genetic combinations from outcrossing events.
Journal ArticleDOI
Gene flow among wild and domesticated almond species: insights from chloroplast and nuclear markers.
Malou Delplancke,Nadir Alvarez,Anahí Espíndola,Hélène Joly,Laure Benoit,Elise Brouck,Nils Arrigo +6 more
TL;DR: High genetic diversity levels in both species along with substantial and symmetric gene flow between the domesticated P. dulcis and the wild P. orientalis suggests that ad hoc transgene containment strategies would be required if genetically modified cultivars were introduced in the northwestern Mediterranean.
