Data from: Historical collections reveal patterns of diffusion of sweet potato in Oceania obscured by modern plant movements and recombination

Caroline Roullier, Laure Benoit, Doyle B. McKey & Vincent Lebot
The history of sweet potato in the Pacific has long been an enigma. Archaeological, linguistic and ethnobotanical data suggest that prehistoric human-mediated dispersal events contributed to the distribution in Oceania of this American domesticate. According to the “tripartite hypothesis”, sweet potato was introduced into Oceania from South America in pre-Columbian times, and was then later newly introduced, and diffused widely across the Pacific, by Europeans via two historically documented routes from Mexico and the Caribbean....

Data from: Genetic mapping of two components of reproductive isolation between two sibling species of moths, Ostrinia nubilalis and O. scapulalis

Réjane Streiff, Brigitte Courtois, Serge Meusnier & Denis Bourguet
We report the quantitative trait loci (QTL) mapping of reproductive isolation traits between Ostrinia nubilalis (the European corn borer) and its sibling species O. scapulalis (the Adzuki bean borer), focusing on two traits: mating isolation (mi) and pheromone production (Pher). Four genetic maps were generated from two backcross families, with two maps (one chromosomal map and one linkage map) per backcross. We located 165–323 AFLP markers on these four maps, resulting in the identification of...

Data from: On the origin of sweet potato (Ipomoea batatas (L.) Lam) genetic diversity in New Guinea, a secondary centre of diversity

Caroline Roullier, Rosa Kambouo, Janet Paofa, Doyle McKey & Vincent Lebot
New Guinea is considered the most important secondary centre of diversity for sweet potato (Ipomoea batatas). We analysed nuclear and chloroplast genetic diversity of 417 New Guinea sweet potato landraces, representing agro-morphological diversity collected throughout the island, and compared this diversity with that in tropical America. The molecular data reveal moderate diversity across all accessions analysed, lower than that found in tropical America. Nuclear data confirm previous results, suggesting that New Guinea landraces are principally...

Data from: The “Dr Jekyll and Mr Hyde fungus”: noble rot versus gray mold symptoms of Botrytis cinerea on grapes

Elisabeth Fournier, Pierre Gladieux & Tatiana Giraud
Many cryptic species have recently been discovered in fungi, especially in fungal plant pathogens. Cryptic fungal species co-occurring in sympatry may occupy slightly different ecological niches, for example infecting the same crop plant but specialized on different organs or having different phenologies. Identifying cryptic species in fungal pathogens of crops and determining their ecological specialization is therefore crucial for disease management. Here we addressed this question in the ascomycete Botrytis cinerea, the agent of grey...

Data from: Molecular characterisation of trophic ecology within an island radiation of insect herbivores (Curculionidae: Entiminae: Cratopus).

James J. N. Kitson, Ben H. Warren, F. B. Vincent Florens, Claudia Baider, Dominique Strasberg & Brent C. Emerson
The phytophagous beetle family Curculionidae is the most species-rich insect family known, with much of this diversity having been attributed to both co-evolution with food plants and host-shifts at key points within the early evolutionary history of the group. Less well understood is the extent to which patterns of host use vary within or among related species, largely because of the technical difficulties associated with quantifying this. Here we develop a recently characterised molecular approach...

Data from: Genome mining reveals the genus Xanthomonas to be a promising reservoir for new bioactive non-ribosomally synthesized peptides

Völler, Julie Noëll, Isabelle Pieretti, Saskia Rausch, Valérie Verdier, Stéphane Poussier, Philippe Rott, Roderich D. Süssmuth & Stéphane Cociancich
Background: Various bacteria can use non-ribosomal peptide synthesis (NRPS) to produce peptides or other small molecules. Conserved features within the NRPS machinery allow the type, and sometimes even the structure, of the synthesized polypeptide to be predicted. Thus, bacterial genome mining via in silico analyses of NRPS genes offers an attractive opportunity to uncover new bioactive non-ribosomally synthesized peptides. Xanthomonas is a large genus of Gram-negative bacteria that cause disease in hundreds of plant species....

Data from: Cryptic diversity and gene flow among three African agricultural pests: Ceratitis rosa, Ceratitis fasciventris and Ceratitis anonae (Diptera, Tephritidae)

Massimiliano Virgilio, Helene Delatte, Serge Quilici, Thierry Backeljau & Marc De Meyer
The ‘Ceratitis FAR complex’ is a species complex of African fruit flies (Diptera, Tephritidae) including the major agricultural pest Ceratitis rosa and the morphologically similar Ceratitis fasciventris and Ceratitis anonae. To resolve their intra- and interspecific genetic relationships and to estimate gene flow within this complex, we surveyed allelic variation at 16 microsatellite loci in 27 African populations of the three morphospecies. Interpopulation genetic distances and individual Bayesian assignments distinguished five genotypic clusters: two involving...

Data from: Estimation of the dispersal of a major pest of maize by cline analysis of a temporary contact zone between two invasive outbreaks

Gérald Bermond, Aurélie Blin, Elodie Vercken, Virginie Ravigné, Adrien Rieux, Sophie Mallez, Thibaut Morel-Journel, Thomas Guilllemaud & Thomas Guillemaud
Dispersal is a key factor in invasion, and in the persistence and evolution of species. Despite the importance of estimates of dispersal distance, dispersal measurement remains a real methodological challenge. In this study, we characterized dispersal by exploiting a specific case of biological invasion, in which multiple introductions in disconnected areas lead to secondary contact between two differentiated expanding outbreaks. By applying cline theory to this ecological setting, we estimated σ, the standard deviation of...
