The target of β-lactam antibiotics is the D,D-transpeptidase activity of penicillin-binding proteins (PBPs) for synthesis of 4→3 cross-links in the peptidoglycan of bacterial cell walls. Unusual 3→3 cross-links formed by L,D-transpeptidases were first detected in Escherichia coli more than four decades ago, however no phenotype has previously been associated with their synthesis. Here we show that production of the L,D-transpeptidase YcbB in combination with elevated synthesis of the (p)ppGpp alarmone by RelA lead to full...

Fitness can be profoundly influenced by the age at first reproduction (AFR), but to date the AFR-fitness relationship only has been investigated intraspecifically. Here we investigated the relationship between AFR and average lifetime reproductive success (LRS) across 34 bird species. We assessed differences in the deviation of the Optimal AFR (i.e., the species-specific AFR associated with the highest LRS) from the age at sexual maturity, considering potential effects of life-history as well as social and...

Abdel Kader Naino Jika, Yann Dussert, Christine Raimond, Eric Garine, Anne Luxereau, Najat Takvorian, Ramatou Sidikou Djermakoye, Toudou Adam & Thierry Robert
Despite of a growing interest in considering the role of sociological factors in seed exchanges and their consequences on the evolutionary dynamics of agro-biodiversity, very few studies assessed the link between ethno-linguistic diversity and genetic diversity patterns in small-holder farming systems. This is key for optimal improvement and conservation of crop genetic resources. Here, we investigated genetic diversity at 17 SSR markers of pearl millet landraces (varieties named by farmers) in the Lake Chad Basin....

Data from: Past and present dynamics of sorghum and pearl millet diversity in Mount Kenya region

Vanesse Labeyrie, Monique Deu, Yann Dussert, Bernard Rono, Françoise Lamy, Charles Marangu, Dan Kiambi, Caroline Calatayud, Geo Coppens D’Eeckenbrugge, Thierry Robert, Christian Leclerc & Geo Coppens D'Eeckenbrugge
Crop populations in smallholder farming systems are shaped by the interaction of biological, ecological and social processes, occurring on different spatiotemporal scales. Understanding these dynamics is fundamental for the conservation of crop genetic resources. In this paper we investigated the processes involved in sorghum and pearl millet diversity dynamics on Mount Kenya. Surveys were conducted in ten sites distributed along two elevation transects and occupied by six ethnolinguistic groups. Varieties of both species grown in...

Data from: Crop-to-wild gene flow and its fitness consequences for a wild fruit tree: towards a comprehensive conservation strategy of the wild apple in Europe

Alice Feurtey, Amandine Cornille, Jacqui A. Shykoff, Alodie Snirc & Tatiana Giraud
Crop-to-wild gene flow can reduce the fitness and genetic integrity of wild species. Malus sylvestris, the European crabapple fruit tree, in particular is threatened by the disappearance of its habitat and by gene flow from its domesticated relative, Malus domestica. With the aims of evaluating threats for M. sylvestris and of formulating recommendations for its conservation, we studied here, using microsatellite markers and growth experiments: i) hybridization rates in seeds and trees from a French...

Data from: Brain size and the risk of getting shot

Anders Pape Møller & Johannes Erritzøe
Hunting kills hundreds of millions of animals annually, potentially constituting an important selection pressure on hunted species. We hypothesized that hunted individuals differing from survivors by having better ability to distinguish between dangerous humans and other human beings would be at a selective advantage. We tested whether shot individual birds had smaller brains than survivors, under the assumption that individuals with larger brains had superior escape ability. We used a large database on birds from...

Data from: Life history evolution and cellular mechanisms associated with increased size in high-altitude Drosophila

Justin B. Lack, Amir Yassin, Quentin D. Sprengelmeyer, Evan J. Johanning, Jean R. David & John E. Pool
Understanding the physiological and genetic basis of growth and body size variation has wide-ranging implications, from cancer and metabolic disease to the genetics of complex traits. We examined the evolution of body and wing size in high-altitude Drosophila melanogaster from Ethiopia, flies with larger size than any previously known population. Specifically, we sought to identify life history characteristics and cellular mechanisms that may have facilitated size evolution. We found that the large-bodied Ethiopian flies laid...

Data from: Continental-level population differentiation and environmental adaptation in the mushroom Suillus brevipes

Sara Branco, Ke Bi, Hui-Ling Liao, Pierre Gladieux, Helene Badouin, Chris E. Ellison, Nhu H. Nguyen, Rytas Vilgalys, Kabir G. Peay, John W. Taylor, Thomas D. Bruns & Christopher E. Ellison
Recent advancements in sequencing technology allowed researchers to better address the patterns and mechanisms involved in microbial environmental adaptation at large spatial scales. Here we investigated the genomic basis of adaptation to climate at the continental scale in Suillus brevipes, an ectomycorrhizal fungus symbiotically associated with the roots of pine trees. We used genomic data from 55 individuals in seven locations across North America to perform genome scans to detect signatures of positive selection and...

Data from: New insights into the history of domesticated and wild apricots and its contribution to Plum pox virus resistance

Stéphane Decroocq, Amandine Cornille, David Tricon, Sevda Babayeva, Aurélie Chague, Jean-Philippe Eyquard, Raul Karychev, Svetlana Dolgikh, Tatiana Kostritsyna, Shuo Liu, Weisheng Liu, Wenjuan Geng, Kang Liao, Bayram Asma, Zeynal Akparov, Tatiana Giraud, Veronique Decroocq & Bayram M. Asma
Studying domesticated species and their wild relatives allows understanding of the mechanisms of population divergence and adaptation, and identifying valuable genetic resources. Apricot is an important fruit in the Northern hemisphere, where it is threatened by the Plum pox virus (PPV), causing the sharka disease. The histories of apricot domestication and of its resistance to sharka are however still poorly understood. We used 18 microsatellite markers to genotype a collection of 230 wild trees from...

Data from: Association mapping for phenology and plant architecture in maize shows higher power for developmental traits compared with growth influenced traits

Sophie Bouchet, Pascal Bertin, Thomas Presterl, Philippe Jamin, Denis Coubriche, Brigitte Gouesnard, Jacques Laborde & Alain Charcosset
Plant architecture, phenology and yield components of cultivated plants have repeatedly been shaped by selection to meet human needs and adaptation to different environments. Here we assessed the genetic architecture of 24 correlated maize traits that interact during plant cycle. Overall, 336 lines were phenotyped in a network of 9 trials and genotyped with 50K single-nucleotide polymorphisms. Phenology was the main factor of differentiation between genetic groups. Then yield components distinguished dents from lower yielding...

Data from: Genetic diversity of oilseed rape fields and feral populations in the context of coexistence with GM crops

Diane Bailleul, Sébastien Ollier & Jane Lecomte
Despite growing concern about transgenes escaping from fields, few studies have analysed the genetic diversity of crops in an agroecosystem over several years. Accurate information about the dynamics and relationship of the genetic diversity of crops in an agroecosystem is essential for risk assessment and policies concerning the containment of genetically modified crops and their coexistence with crops grown by conventional practices. Here, we analysed the genetic diversity of oilseed rape plants from fields and...

Data from: Evolutionary radiations of Proteaceae are triggered by the interaction between traits and climates in open habitats

Renske E. Onstein, Gregory J. Jordan, Hervé Sauquet, Peter H. Weston, Yanis Bouchenak-Khelladi, Ian J. Wright, Raymond J. Carpenter & H. Peter Linder
Aim: Ecologically driven diversification can create spectacular diversity in both species numbers and form. However, the prediction that the match between intrinsic (e.g. functional trait) and extrinsic (e.g. climatic niche) variables may lead to evolutionary radiation has not been critically tested. Here, we test this hypothesis in the Southern Hemisphere plant family Proteaceae, which shows a spectacular diversity in open mediterranean shrublands in the Southwest Australian Floristic Region (SWAFR) and the Cape Floristic Region (CFR)....

Data from: Migratory connectivity and effects of winter temperatures on migratory behaviour of the European robin Erithacus rubecula: a continent-wide analysis

Roberto Ambrosini, José Cuervo, Chris Du Feu, Wolfgang Fiedler, Musitelli Federica, Diego Rubolini, Beatrice Sicurella, Fernando Spina, Nicola Saino, Anders Møller & Federica Musitelli
1. Many partially migratory species show phenotypically divergent populations in terms of migratory behaviour, with climate hypothesized to be a major driver of such variability through its differential effects on sedentary and migratory individuals. 2. Based on long-term (1947–2011) bird ringing data, we analysed phenotypic differentiation of migratory behaviour among populations of the European robin Erithacus rubecula across Europe. 3. We showed that clusters of populations sharing breeding and wintering ranges varied from partial (British...
