Thématiques de recherche

Chimiste de formation intéressée par la physiologie des plantes, leur métabolisme et leurs interactions avec l’environnement, je travaille sur deux projets différents autour des Composés Organiques Volatiles (COV) émis par les plantes.

Projet BIOMASP+

Les plantes émettent des composés organiques volatiles qui influencent considérablement les propriétés physicochimiques de l’atmosphère : capacité oxydante, temps de résidence des gaz à effet de serre, formation d’aérosols organiques secondaires… Le but du projet BIOMASP+ est de comprendre ces interactions biosphère-atmosphère ainsi que l’effet de la pollution sur ces émissions.

Dans le cadre de ce projet, les flux de COV biogéniques sont étudiés au niveau de la plante mais également au niveau du couvert végétal sur deux sites d’étude : la forêt de Puéchabon (Gard, France) et la forêt Atlantique (São Paulo, Brésil). Il s’agira de mieux comprendre les facteurs inhérents et externes influençant les émissions de COV par les plantes.

Projet CapZeroPhyto

Les COV émis par les plantes peuvent avoir différentes fonctions, telles que l’attraction de pollinisateurs, la répulsion d’herbivores ou encore dans l’interaction plante-plante. En particulier, les COV émis par une plante lors d’attaques par un herbivore peuvent déclencher chez une autre plante réceptrice ses propres mécanismes de défense (priming). Cette interaction plante-plante est d’un grand intérêt en agroécologie pour stimuler les défenses des plantes contre les ravageurs, et ainsi proposer de nouvelles stratégies de protections des cultures.

Dans le cadre de ce projet, l’interaction entre plants de tomates (Solanaceae) est étudiée en réponse à l’attaque par le ravageur Tuta absoluta. Englobant une approche phylogénétique, il s’agit de voir comment cette interaction varie avec la distance phylogénétique entre les plants.

Research interests

Chemist by training with a strong interest in the physiology of plants, their metabolism and their interaction with the environment, I am currently working on two distinct projects structured around Volatile Organic Compounds (VOCs) emitted by plants.

BIOMASP+ project

Plants emit many volatile organic compounds which can have a great impact on the physicochemical properties of the atmosphere: oxidative capacity, life-time of greenhouse gases, formation of secondary organic aerosols… The aim of the project BIOMASP+ centers around understanding the biosphere-atmosphere interactions and the effect of pollution on these interactions.

In this project, biogenic VOCs fluxes are studied at the plant level but also at the canopy level on two different sites: Puechabon forest (Gard, France) and the Mata Atlantica (São Paulo, Brazil). The main interest is to understand the inherent and external factors modulating VOCs emissions by the plants.

CapZeroPhyto

VOCs emitted by plants can play different major roles, such as attracting pollinators, repelling herbivores or in plant-plant interaction. Specially, VOCs emitted by a plant species under herbivore attack can trigger on another plant its own defense mechanisms (priming). This plant-plant interaction is of high interest in agroecology, to promote crop defense against pest, and thus offering new strategies for crop protection.

In this aim, the interaction between tomato plants (Solanaceae) is studied in response to the attack by the specialist pest Tuta absoluta. Within a phylogenetic approach, the main thrust of the project is to answer how this plant-plant interactions vary with the phylogenetic distance between plants.

Research interests

Soil scientist fascinated by plant ecophysiology, my research focusses on soil-plant interactions in both natural and controlled conditions. I am particularly interested in silicon (Si), a major component of the Earth’s crust and soils, that is increasingly considered as a key element in plant ecology and agriculture through the fantastic process of biosilicification (mineral deposits in plant organs as seen on the left).

Research thematic

I combine expertise in soil science and plant ecophysiology to work on three different research axes:

• The influence of soil properties, and in particular their evolution over time through the use of long-term chronosequences, on silicon cycling (e.g., soil Si pools and fluxes, Si availability for plants, Si uptake by plants and silicification, biological versus lithological control on Si cycling)
• The control of overlooked biotic factors on soil-plant Si mobility (e.g., soil microorganisms, large herbivores, root exudates), and how they could be leveraged to increase crop Si status through specific agricultural practices.
• Developing functional trait-based approaches to better understand the role and functions of Si and silicification in plant ecophysiology, and how it aligns with major ecological theories (plant growth/defense tradeoff, plant economics spectrum, resource availability hypothesis, etc.).

Project

The objective of this PhD project is to better understand how wild populations of great tits and blue tits are affected by urbanization and what mechanisms are involved in the observed phenotypic differences between urban and forest populations. This study will rely on the long-term population monitoring in urban and forest habitats established in Montpellier (CEFE TIT PROJECT) , as well as on comparative analyses with the city of Paris. The thesis will particularly explore physiological aspects that have not been studied thus far. Given the characteristics of the urban environment, which is more stressful and has higher temperatures, physiological adaptations to urban life are expected to be observed. Variations in the endocrine system between urban and forest environments will be studied, focusing on stress and reproductive hormones. Additionally, aspects of respirometry will be investigated, with the primary question being: do urban birds have a metabolism pre-adapted to high temperatures due to living in an urban heat island effect environment? In a second part, the project aims to dissect how urban phenotypic shifts are driven by genetic change or plasticity. To study this aspect, common garden experiments have been set up. Data from individuals raised under similar environmental conditions can be compared to wild individuals, thus observing whether phenotypic differences between urban and forest habitats are maintained or not.

PhD thesis subject (2024-2027): Drought effects on carbon assimilation and allocation in living tree biomass in forests

Supervisors: Jean-Marc Limousin (CNRS-CEFE) and Maxime Cailleret (INRAE-RECOVER)

Forests are a major player in the global carbon (C) cycle and at the heart of the climate change mitigation initiatives of the 2015 Paris Agreement, but models strongly disagree on the projection of this C sink under future climate change. Our current understanding of climate change effects on forest’s carbon sequestration is limited by uncertainties around the allocation of carbon among the different tree organs and the link between carbon photosynthetic assimilation and sequestration in perennial tree biomass.

The main objectives of this PhD thesis are to quantify how the C allocation in tree biomass changes among the different organs (wood, roots, leaves and reproductive organs) in response to increasing water stress and decreasing C assimilation. The research project will use both the results of five long-term rainfall manipulation experiments set in different forest ecosystems (three Mediterranean forests in Southern France, one temperate forest in North-Eastern France, and one eucalypt plantation in Brazil), and of carbon fluxes measured by eddy covariance in different forest sites within the ICOS network, to study the experimental and inter-annual effects of changing water availability. It will involve the analysis and synthesis of existing data and the collection of new data using homogenized and innovative protocols in every site, especially regarding the belowground compartment that is generally understudied in forest ecosystems.

The thesis will be articulated around three main research axes: i) improve our understanding of the link between photosynthetic C uptake and wood stem growth; ii) investigate the effects of drought on tree architecture and C allocation among the different aerial tree organs; iii) quantify belowground C allocation and its response to drought.

I am interested in how changes in biodiversity and environmental conditions (atmospheric carbon dioxide, temperature, precipitation) affect plant-soil interactions, with a particular focus on plant litter and decomposer organisms. The main research goal is a mechanistic understanding of the drivers of biogeochemical cycles using experimental approaches in the field (alpine, temperate, Mediterranean and tropical forest ecosystems) and the laboratory.

Personal interests

As an ecophysiologist, my research is focused on the adaptive strategies of plants under drought (Volaire, 2018, Global Change Biology). I have particularly analysed the adaptive strategies to cope with severe water deficit, such as summer dormancy (Volaire & Norton, 2006, Annals of Botany). I also investigate the  dehydration tolerance and embolism resistance of perennial herbaceous plants under severe summer droughts as occurring in Mediterranean and semi-arid areas.  We proposed a critical view of the so called 'functional' traits that are increasingly challenged as unsuitable to fully understand plant and communities functioning (Volaire et al., 2021 Ecology and Evolution). As a consequence, I highlight the importance of seasonal phenological adaptations across species and types to survive dehydration stress (drought, frost), based on the important framework in ecology, the 'growth-stress survival' tradeoff' (Volaire et al., 2022 Annals of Botany). I am developing collaborative research projects with geneticists and ecologists to understand plant traits and strategies associated with drought survival with application to plant breeding in forage species for better adaptation to increasing aridity under climate change.

Intérêts personnels
Mes travaux portent sur les stratégies adaptatives des plantes à la sécheresse. Je travaille notamment sur les espèces herbacées pérennes sous sécheresses estivales sévères de type méditerranéen. Je couple des approches en écophysiologie, agronomie et écologie fonctionnelle. L’objectif principal est d’analyser le fonctionnement des espèces et communautés herbacées sous contrainte hydrique forte dans le cadre du changement climatique. Un cadre conceptuel et terminologique unifié des stratégies adaptatives des plantes à la sécheresse a été proposé en 2018. Les études portent notamment sur la stratégie de dormance estivale et plus largement sur la généricité du compromis fonctionnel entre potentiel de croissance et survie au stress. Une revue multi-espèces et multi-stress a été publiée en 2023 dans Annals of Botany qui propose de considérer mieux la phénologie des plantes au travers d'un 'Plant economics spectrum' saisonnier.
