- My current research is in the field of Evolutionary Developmental Genetics (evo-devo). Evo-devo brings additional important complement to the Modern Synthesis theory at least for multicellular organisms, pinpointing the importance of development as a potential source of constraints that interplay with natural selection to produce morphological diversity in the course of evolution.
Since the 2000s, I have been focussing on the evolution of floral traits, namely floral symmetry and petal formation and shape (1 and 2, 4, 6, 8 and 9). I chose these traits because they have evolved several times independently during angiosperm diversification, most probably as a result of convergent selective pressures for pollination efficiency.
Such traits are interesting subjects for evo-devo research, because they provide the opportunity to examine the relative importance of developmental/historical constraints and selection in morphological evolution. The comparative analyses of genes and gene networks in a phylogenetic framework allow the generality of the toolkit and evolutionary tinkering concepts to be appreciated.
External Collaborators on my present research: Sophie Nadot (ESE), Florian Jabbour (MNHN), Etienne Delannoy (URGGV, IPS2), Patrick Laufs (IJPB).
My previous research has also been built on my persistent interest in the genetic and molecular bases of morphological diversity in plants. The underlying hypothesis of my approaches has been that the polymorphism of regulatory factors is of primary importance for morphological evolution.
I have used quantitative proteomics to have an access to the variability of regulatory mechanisms of gene expression in maize and to decipher their genetic architecture (11). I analyzed the molecular polymorphism and diversity of candidate genes in wild and cultivated accessions in the genus Zea, to get an insight into the molecular bases of the response to selection for kernel storage compounds during and after domestication (5, 7). I have also been interested in the evolutionary history of gene families (duplication, gene loss, patterns of selection), some members of which have been found to play important roles in morphological variation (3, 10).
