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

PLoS One 2014Justine 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 survival… 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 2013Maryline 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 grow… 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 2012Marie 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 regulator… 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 2012François 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 test… Continue reading A common genetic basis to the origin of the leaf economics spectrum and metabolic scaling allometry

Arabidopsis growth under prolonged high temperature and water deficit: independent or interactive effects?

Plant, Cell & Environment 2012 Denis Vile, Marjorie Pervent, Michaël Belluau, François Vasseur, Justine Bresson, Bertrand Muller, Christine Granier, Thierry Simonneau High temperature (HT) and water deficit (WD) are frequent environmental constraints restricting plant growth and productivity. These stresses often occur simultaneously in the field, but little is known about their combined impacts on plant… Continue reading Arabidopsis growth under prolonged high temperature and water deficit: independent or interactive effects?

Changes in light intensity reveal a major role for carbon balance in Arabidopsis responses to high temperature

Plant, Cell & Environment 2011François Vasseur, Florent Pantin, Denis Vile High temperature (HT) is a major limiting factor for plant productivity. Because some responses to HT, notably hyponasty, resemble those encountered in low light (LL), we hypothesized that plant responses to HT are under the control of carbon balance. We analysed the interactive effects of… Continue reading Changes in light intensity reveal a major role for carbon balance in Arabidopsis responses to high temperature
