Data from: Phylogeography and niche modelling of the relict plant Amborella trichopoda (Amborellaceae) reveal multiple Pleistocene refugia in New CaledoniaValérie Poncet, François Munoz, Jérôme Munzinger, Yohan Pillon, Céline Gomez, Marie Couderc, Christine Tranchant-Dubreuil, Serge Hamon & Alexandre De Kochko
Amborella trichopoda Baill. (Amborellaceae, Amborellales), the sole living member of the sister group to all other extant Angiosperms, is endemic to New Caledonia. We addressed the intraspecific phylogeography of Amborella by investigating whether its present population genetic structure could be related to its current and past habitats. We found moderate range-wide genetic diversity based on nuclear microsatellite data, and detected four well-differentiated, geographically distinct genetic groups using Bayesian clustering analyses. We modeled the ecological niche...
Data from: Host resistance, population structure and the long-term persistence of bubonic plague: contributions of a modelling approach in the Malagasy focusFanny Gascuel, Marc Choisy, Jean-Marc Duplantier, Florence Débarre & Carine Brouat
Although bubonic plague is an endemic zoonosis in many countries around the world, the factors responsible for the persistence of this highly virulent disease remain poorly known. Classically, the endemic persistence of plague is suspected to be due to the coexistence of plague resistant and plague susceptible rodents in natural foci, and/or to a metapopulation structure of reservoirs. Here, we test separately the effect of each of these factors on the long-term persistence of plague....
Data from: Genome mining reveals the genus Xanthomonas to be a promising reservoir for new bioactive non-ribosomally synthesized peptidesMonique Royer, Ralf Koebnik, Mélanie Marguerettaz, Valérie Barbe, Guillaume P. Robin, Chrystelle Brin, Sébastien Carrere, Camila Gomez, Manuela Hügelland, Ginka H. 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: Wolbachia increases susceptibility to Plasmodium infection in a natural systemFlore Zélé, Antoine Nicot, Arnaud Berthomieu, Mylène Weill, Olivier Duron, Ana Rivero & F. Zele
Current views about the impact of Wolbachia on Plasmodium infections are almost entirely based on data regarding artificially transfected mosquitoes. This work has shown that Wolbachia reduces the intensity of Plasmodium infections in mosquitoes, raising the exciting possibility of using Wolbachia to control or limit the spread of malaria. Whether natural Wolbachia infections have the same parasite-inhibiting properties is not yet clear. Wolbachia–mosquito combinations with a long evolutionary history are, however, key for understanding what...
