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: Ecological co-associations influence species’ responses to past climatic change: an example from a Sonoran Desert bark beetle

Ryan C. Garrick, John D. Nason, Rodney J. Dyer & Juan F. Fernández-Manjarrés
Ecologically interacting species may have phylogeographic histories that are shaped both by features of their abiotic landscape, and by biotic constraints imposed by their co-association. The Baja California peninsula provides an excellent opportunity to examine the influence of abiotic vs. biotic factors on patterns of diversity in plant-insect species. This is because past climatic and geological changes impacted the genetic structure of plants quite differently to that of co-distributed free-living animals (e.g., herpetofauna and small...

Data from: Phenotypic and genotypic convergences are influenced by historical contingency and environment in yeast

Aymé Spor, Daniel J. Kvitek, Thibault Nidelet, Juliette Martin, Judith Legrand, Christine Dillmann, Aurélie Bourgais, Dominique De Vienne, Gavin Sherlock & Delphine Sicard
Different organisms have independently and recurrently evolved similar phenotypic traits at different points throughout history. This phenotypic convergence may be caused by genotypic convergence and in addition, constrained by historical contingency. To investigate how convergence may be driven by selection in a particular environment and constrained by history, we analyzed nine life-history traits and four metabolic traits during an experimental evolution of six yeast strains in four different environments. In each of the environments, the...

Data from: Conserved class of queen pheromones stops social insect workers from reproducing

Annette Van Oystaeyen, Ricardo Caliari Oliveira, Luke Holman, Jelle S. Van Zweden, Carmen Romero, Cintia A. Oi, Patrizia D'Ettorre, Mohammadreza Khalesi, Johan Billen, Felix Wäckers, Jocelyn G. Millar & Tom Wenseleers
A major evolutionary transition to eusociality with reproductive division of labor between queens and workers has arisen independently at least 10 times in the ants, bees, and wasps. Pheromones produced by queens are thought to play a key role in regulating this complex social system, but their evolutionary history remains unknown. Here, we identify the first sterility-inducing queen pheromones in a wasp, bumblebee, and desert ant and synthesize existing data on compounds that characterize female...

Data from: Thank you for not flowering: conservation genetics and gene flow analysis of native and non-native populations of Fraxinus (Oleaceae) in Ireland

Muriel Thomasset, Trevor R. Hodkinson, Gwendal Restoux, Nathalie Frascaria-Lacoste, Gerry C. Douglas & Juan F. Fernandez-Manjarres
The risks of gene flow between interfertile native and introduced plant populations are greatest when there is no spatial isolation of pollen clouds and phenological patterns overlap completely. Moreover, invasion probabilities are further increased if introduced populations are capable of producing seeds by selfing. Here we investigated the mating system and patterns of pollen-mediated gene flow among populations of native ash (Fraxinus excelsior) and mixed plantations of non-native ash (F. angustifolia and F. excelsior) as...

Data from: Why do mixotrophic plants stay green? A comparison between green and achlorophyllous orchid individuals in situ

Melanie Roy, Cedric Gonneau, Alain Rocheteau, Daniel Berveiller, Jean-Claude Thomas, Claire Damesin, Marc André Selosse & M.-A. Selosse
Some forest plants adapt to shade by mixotrophy, i.e., they obtain carbon both from photosynthesis and from their root mycorrhizal fungi. Fully achlorophyllous species using exclusively fungal carbon (the so-called mycoheterotrophic plants) have repeatedly evolved from such mixotrophic ancestors. However, adaptations for this evolutionary transition, and the reasons why it has happened a limited number of times, remain unknown. We investigated this using achlorophyllous variants (i.e., albinos) spontaneously occurring in Cephalanthera damasonium, a mixotrophic orchid....

Data from: Induction of sexual reproduction and genetic diversity in the cheese fungus Penicillium roqueforti

Jeanne Ropars, Manuela López-Villavicencio, Joëlle Dupont, Alodie Snirc, Guillaume Gillot, Monika Coton, Jean-Luc Jany, Emmanuel Coton & Tatiana Giraud
The emblematic fungus Penicillium roqueforti is used throughout the world as a starter culture in the production of blue-veined cheeses. Like other industrial filamentous fungi, P. roqueforti was thought to lack a sexual cycle. However, an ability to induce recombination is of great economic and fundamental importance, as it would make it possible to transform and improve industrial strains, promoting the creation of novel phenotypes and eliminating the deleterious mutations that accumulate during clonal propagation....

Data from: Local dynamics of a fast evolving sex-ratio system in Drosophila simulans

Héloïse Bastide, Pierre R. Gérard, David Ogereau, Michel Cazemajor & Catherine Montchamp-Moreau
By distorting Mendelian transmission to their own advantage, X-linked meiotic drive elements can rapidly spread in natural populations, generating a sex-ratio bias. One expected consequence is the triggering of a coevolutionary arms race between the sex chromosome that carries the distorter and suppressors counteracting its effect. Such an arms race has been theoretically and experimentally established, and can have many evolutionary consequences. However, its dynamics in contemporary populations is still poorly documented. Here, we investigate...

Data from: Independent domestications of cultivated tree peonies from different wild peony species

Jun-Hui Yuan, Amandine Cornille, Tatiana Giraud, Fang-Yun Cheng & Yong-Hong Hu
An understanding of plant domestication history provides insights into general mechanisms of plant adaptation and diversification and can guide breeding programs that aim to improve cultivated species. Cultivated tree peonies (genus Paeonia L.) are among the most popular ornamental plants in the world, yet the history of their domestication is still unresolved. Here, we explored whether the domestication in China of historically cultivated peonies, i.e., the common and flare cultivated tree peonies, was a single...
