Evolution of angiosperms
The EVA team conducts fundamental research in the field of plant evolution, at scales ranging from the population (micro-evolutionary scale) to flowering plants (angiosperms) as a whole (macro-evolutionary scale).
These questions are organized into three axes: (1) Evolutionary drivers of plant adaptation and species diversification; (2) evolution of pollen and flowers; (3) description of flowering plant diversity to improve our knowledge in relation to the taxonomy and systematics of these organisms.
The research conducted by the EVA team involves a wide array of approaches including population genetics, molecular evolution, phylogenetic reconstruction, ancestral state reconstruction, molecular dating, cytogenetics, and floral development.

Evolutionary drivers of plant adaptation and species diversification
Research is conducted on wild species and crops using multi-level (from genes to ecosystems) and interdisciplinary (biology, geography, social sciences) approaches.
This research is structured into four major subprojects: 1) variability in genome organization, local adaptation and species diversification, 2) microevolutionary processes promoting species emergence and diversification 3) Genetic architecture of traits involved in adaptation to contrasted environments, and 4) Crop seed exchanges as a driver of population adaptation to global change.
Evolution of pollen and flowers
The flower is a key innovation of the most diversified group of land plants, the angiosperms. Beyond a highly conserved basic groundplan, they present an amazing diversity that is believed to have been largely shaped by the interaction with pollinating agents. Using a variety of approaches combining ancestral state reconstruction, diversification rate analyses, developmental floral biology and evo-devo studies, we aim to unravel (i) the diversification patterns having led to the observed diversity of flowering plants, (ii) the patterns of floral trait evolution, and (iii) the developmental and genetic bases of floral trait diversity.
