Natural selection on the Arabidopsis thaliana genome in present and future climates

Nature 2019 Moises Exposito-Alonso, 500 Genomes Field Experiment Team, Hernán A. Burbano, Oliver Bossdorf, Rasmus Nielsen & Detlef Weigel Through the lens of evolution, climate change is an agent of natural selection that forces populations to change and adapt, or face extinction. However, current assessments of the risk of biodiversity associated with climate change1 do… Continue reading Natural selection on the Arabidopsis thaliana genome in present and future climates

Leaf economics and slow-fast adaptation across the geographic range of Arabidopsis thaliana

Scientific reports 2019 Kevin Sartori, François Vasseur, Cyrille Violle, Etienne Baron, Marianne Gerard, Nick Rowe, Oscar Ayala-Garay, Ananda Christophe, Laura Garcia de Jalón, Diane Masclef, Erwan Harscouet, Maria del Rey Granado, Agathe Chassagneux, Elena Kazakou, Denis Vile Life history strategies of most organisms are constrained by resource allocation patterns that follow a ‘slow-fast continuum’. It… Continue reading Leaf economics and slow-fast adaptation across the geographic range of Arabidopsis thaliana

Secondary metabolites have more influence than morpho‐physiological traits on litter decomposability across genotypes of Arabidopsis thaliana

New Phytologist 2019 Elena Kazakou, François Vasseur, Kevin Sartori, Etienne Baron, Nick Rowe, Denis Vile Although interspecific variation in plant phenotype is recognised to impact afterlife processes such as litter decomposability, it is still unclear which traits and selection pressures explain these relationships. Examining intraspecific variation is crucial to identify and compare trait effects on… Continue reading Secondary metabolites have more influence than morpho‐physiological traits on litter decomposability across genotypes of Arabidopsis thaliana

Nonlinear phenotypic variation uncovers the emergence of heterosis in Arabidopsis thaliana

PLoS biology 2019 François Vasseur, Louise Fouqueau, Dominique de Vienne, Thibault Nidelet, Cyrille Violle, Detlef Weigel Heterosis describes the phenotypic superiority of hybrids over their parents in traits related to agronomic performance and fitness. Understanding and predicting nonadditive inheritance such as heterosis is crucial for evolutionary biology as well as for plant and animal breeding.… Continue reading Nonlinear phenotypic variation uncovers the emergence of heterosis in Arabidopsis thaliana

Transcriptional natural variation at FLM induces synergistic pleiotropy in Arabidopsis thaliana

bioRxiv 2019/1/1 Mathieu Hanemian, François Vasseur, Elodie Marchadier, Elodie Gilbault, Justine Bresson, Isabelle Gy, Cyrille Violle, Olivier Loudet Investigating the evolution of complex phenotypes and the underlying molecular bases of their variation is critical to understand how organisms adapt to the environment. We used leaf growth as a model trait as it is highly integrative… Continue reading Transcriptional natural variation at FLM induces synergistic pleiotropy in Arabidopsis thaliana

Increasing plant group productivity through latent genetic variation for cooperation

bioRxiv 2019/1/1 Samuel E Wuest, Nuno D Pires, Shan Luo, Francois Vasseur, Julie Messier, Ueli Grossniklaus, Pascal A Niklaus Technologies for crop breeding have become increasingly sophisticated, yet it remains unclear whether these advances are sufficient to meet future demands. A major challenge with current crop selection regimes is that they are often based on… Continue reading Increasing plant group productivity through latent genetic variation for cooperation

Climate as a driver of adaptive variations in ecological strategies in Arabidopsis thaliana

Annals of Botany 2018 François Vasseur, Kevin Sartori, Etienne Baron, Florian Fort, Elena Kazakou, Jules Segrestin, Eric Garnier, Denis Vile, Cyrille Violle The CSR classification categorizes plants as stress tolerators (S), ruderals (R) and competitors (C). Initially proposed as a general framework to describe ecological strategies across species, this scheme has recently been used to… Continue reading Climate as a driver of adaptive variations in ecological strategies in Arabidopsis thaliana

Image-based methods for phenotyping growth dynamics and fitness components in Arabidopsis thaliana

Plant methods 2018 François Vasseur, Justine Bresson, George Wang, Rebecca Schwab, Detlef Weigel We developed two models to predict plant dry mass and fruit number from the parameters extracted with the analysis of rosette and inflorescence images. Predictive models were trained by sacrificing growing individuals for dry mass estimation, and manually measuring a fraction of… Continue reading Image-based methods for phenotyping growth dynamics and fitness components in Arabidopsis thaliana

Adaptive diversification of growth allometry in the plant Arabidopsis thaliana

Proceedings of the National Academy of Sciences 2018 François Vasseur, Moises Exposito-Alonso, Oscar J Ayala-Garay, George Wang, Brian J Enquist, Denis Vile, Cyrille Violle, Detlef Weigel Are there biological constants unifying phenotypic diversity across scales? Metabolic scaling theory (MST) predicts mathematical regularity and constancy in the allometric scaling of growth rate with body size across… Continue reading Adaptive diversification of growth allometry in the plant Arabidopsis thaliana
