Bananas (Musa spp.), including dessert and cooking types, are giant perennial monocotyledonous herbs of the order Zingiberales, a sister group to the well-studied Poales, which include cereals. Bananas are vital for food security in many tropical and subtropical countries and the most popular fruit in industrialized countries1. The Musa domestication process started some 7,000 years ago in Southeast Asia. It involved hybridizations between diverse species and subspecies, fostered by human migrations2, and selection of diploid...
Data from: Understanding the recent colonization history of a plant pathogenic fungus using population genetic tools and Approximate Bayesian ComputationBenoit Barrès, Jean Carlier, Marc Seguin, Catherine Fenouillet, Christian Cilas & Viginie Ravigné
Understanding the processes by which new diseases are introduced in previously healthy areas is of major interest in elaborating prevention and management policies as well as in understanding the dynamics of pathogen diversity at large spatial scale. In this study, we aimed to decipher the dispersal processes that have led to the emergence of the plant pathogenic fungus Microcyclus ulei, which is responsible for the South American Leaf Blight (SALB) that has affected rubber trees...
Data from: Recent range expansion and agricultural landscape heterogeneity have only minimal effect on the spatial genetic structure of the plant pathogenic fungus Mycosphaerella fijiensisJean Carlier, Adrien Rieux, Viginie Ravigne, Luc De Lapeyre De Bellaire & Marie-Françoise Zapater
Understanding how geographical and environmental features affect genetic variation at both the population and individual levels is crucial in biology, especially in the case of pathogens. However, distinguishing between these factors and the effects of historical range expansion on spatial genetic structure remains challenging. In the present study, we investigated the case of Mycosphaerella fijiensis-a plant pathogenic fungus that has recently colonized an agricultural landscape characterized by the presence of potential barriers to gene flow,...
Data from: The chestnut blight fungus world tour: successive introduction events from diverse origins in an invasive plant fungal pathogen.Cyril Dutech, Benoit Barrès, Julen Bridier, Cécile Robin, Michael G. Milgroom & Virginie Ravigné
Clonal expansion has been observed in several invasive fungal plant pathogens colonizing new areas, raising the question of the origin of clonal lineages. Using microsatellite markers, we retraced the evolutionary history of introduction of the chestnut blight fungus, Cryphonectria parasitica, in North America and western Europe. Combining discriminant analysis of principal components and approximate Bayesian computation analysis, it was shown that several introduction events from genetically differentiated source populations have occurred in both invaded areas....
Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts. Remarkably, their evolutionary history has received little attention, and there is no firm agreement on how many species should be recognized within the black rat complex. This species complex is native to India and Southeast Asia. According to current taxonomic classification, there are three taxa living in sympatry in several parts of Thailand, Cambodia and Lao People's Democratic Republic, where this...
Data from: Comparison of the genetic determinism of two key phenological traits, flowering and maturity dates, in three Prunus species: peach, apricot and sweet cherryPatrick Lambert, David Ruiz, Luca Dondini, Eudald Illa, Jean-Marc Audergon, Stefano Tartarini, Philippe Letourmy, Elisabeth Dirlewanger, José Quéro-Garcia, Loïck Le Dantec, Bénédicte Quilot-Turion & Pere Arus
The present study investigates the genetic determinism of flowering and maturity dates, two traits highly affected by global climate change. Flowering and maturity dates were evaluated on five progenies from three Prunus species, peach, apricot and sweet cherry, during three to eight years. Quantitative trait locus (QTL) detection was performed separately for each year and also by integrating data from all years together. High heritability estimates were obtained for flowering and maturity dates. Several QTLs...
