Genomic basis and evolutionary potential for extreme drought adaptation in Arabidopsis thaliana

Nature ecology & evolution 2018 Moises Exposito-Alonso, Francois Vasseur, Wei Ding, George Wang, Hernán A Burbano, Detlef Weigel As Earth is currently experiencing dramatic climate change, it is of critical interest to understand how species will respond to it. The chance of a species withstanding climate change is likely to depend on the diversity within the… Continue reading Genomic basis and evolutionary potential for extreme drought adaptation in Arabidopsis thaliana

Genetic architecture of nonadditive inheritance in Arabidopsis thaliana hybrids

Proceedings of the National Academy of Sciences 2016 Danelle K Seymour, Eunyoung Chae, Dominik G Grimm, Carmen Martín Pizarro, Anette Habring-Müller, François Vasseur, Barbara Rakitsch, Karsten M Borgwardt, Daniel Koenig, Detlef Weigel The ubiquity of nonparental hybrid phenotypes, such as hybrid vigor and hybrid inferiority, has interested biologists for over a century and is of… Continue reading Genetic architecture of nonadditive inheritance in Arabidopsis thaliana hybrids

PHENOPSIS: Quelles évolutions technologiques du premier automate de phénotypage des plantes?

Cahier des Techniques de l'INRA 2016 Myriam Dauzat, Anaëlle Dambreville, Justine Bresson, Denis Vile, Bertrand Muller, Vincent Negre, Garance Koch, François Vasseur, Alexis Bediee, Maxence Desigaux, Denis Fourreau, Christine Granier Afin de répondre aux besoins de phénotypage à haut débit dans le domaine végétal, le LEPSE (Laboratoire d’Ecophysiologie des plantes sous stress environnementaux) et la… Continue reading PHENOPSIS: Quelles évolutions technologiques du premier automate de phénotypage des plantes?

Quantifying spatial heterogeneity of chlorophyll fluorescence during plant growth and in response to water stress

Plant Methods 2015 Justine Bresson, François Vasseur, Myriam Dauzat, Garance Koch, Christine Granier, Denis Vile We developed a method to quantify the dynamics of spatial heterogeneity of photosynthetic efficiency through the distribution-based analysis of Fv/Fm values. The method was applied to Arabidopsis thaliana grown under well-watered and severe water deficit (survival rate of 40%). First,… Continue reading Quantifying spatial heterogeneity of chlorophyll fluorescence during plant growth and in response to water stress

Testing models for the leaf economics spectrum with leaf and whole-plant traits in Arabidopsis thaliana

AoB Plants 2015 Benjamin Blonder, François Vasseur, Cyrille Violle, Bill Shipley, Brian J Enquist, Denis Vile The leaf economics spectrum (LES) describes strong relationships between multiple functional leaf traits that determine resource fluxes in vascular plants. Five models have been proposed to explain these patterns: two based on patterns of structural allocation, two on venation… Continue reading Testing models for the leaf economics spectrum with leaf and whole-plant traits in Arabidopsis thaliana

Multivariate genetic analysis of plant responses to water deficit and high temperature revealed contrasting adaptive strategies

Journal of experimental botany 2014 François Vasseur, Thibaut Bontpart, Myriam Dauzat, Christine Granier, Denis Vile How genetic factors control plant performance under stressful environmental conditions is a central question in ecology and for crop breeding. A multivariate framework was developed to examine the genetic architecture of performance-related traits in response to interacting environmental stresses. Ecophysiological… Continue reading Multivariate genetic analysis of plant responses to water deficit and high temperature revealed contrasting adaptive strategies

Interact to survive: Phyllobacterium brassicacearum improves Arabidopsis tolerance to severe water deficit and growth recovery

PLoS One 2014 Justine Bresson, François Vasseur, Myriam Dauzat, Marc Labadie, Fabrice Varoquaux, Bruno Touraine, Denis Vile Mutualistic bacteria can alter plant phenotypes and confer new abilities to plants. Some plant growth-promoting rhizobacteria (PGPR) are known to improve both plant growth and tolerance to multiple stresses, including drought, but reports on their effects on plant… Continue reading Interact to survive: Phyllobacterium brassicacearum improves Arabidopsis tolerance to severe water deficit and growth recovery

Phenotyping the kinematics of leaf development in flowering plants: recommendations and pitfalls

Wiley Interdisciplinary Reviews: Developmental Biology 2013 Maryline Lièvre, Nathalie Wuyts, Sarah J Cookson, Justine Bresson, Mélanie Dapp, François Vasseur, Catherine Massonnet, Sébastien Tisné, Mathilde Bettembourg, Crispulo Balsera, Alexis Bédiée, Frédéric Bouvery, Myriam Dauzat, Gaëlle Rolland, Denis Vile, Christine Granier Leaves of flowering plants are produced from the shoot apical meristem at regular intervals and they… Continue reading Phenotyping the kinematics of leaf development in flowering plants: recommendations and pitfalls

Gibberellins regulate the transcription of the continuous flowering regulator, RoKSN, a rose TFL1 homologue

Journal of experimental botany 2012 Marie Randoux, Julien Jeauffre, Tatiana Thouroude, François Vasseur, Latifa Hamama, Marjorie Juchaux, Soulaiman Sakr, Fabrice Foucher The role of gibberellins (GAs) during floral induction has been widely studied in the annual plant Arabidopsis thaliana. Less is known about this control in perennials. It is thought that GA is a major… Continue reading Gibberellins regulate the transcription of the continuous flowering regulator, RoKSN, a rose TFL1 homologue

A common genetic basis to the origin of the leaf economics spectrum and metabolic scaling allometry

Ecology letters 2012 François Vasseur, Cyrille Violle, Brian J Enquist, Christine Granier, Denis Vile Many facets of plant form and function are reflected in general cross‐taxa scaling relationships. Metabolic scaling theory (MST) and the leaf economics spectrum (LES) have each proposed unifying frameworks and organisational principles to understand the origin of botanical diversity. Here, we… Continue reading A common genetic basis to the origin of the leaf economics spectrum and metabolic scaling allometry
