Cell wall proteins and Development

The plant cell wall is a dynamic structure playing important roles during growth, differentiation, during the interactions with pathogens and in response to environmental abiotic factors. The cell wall is both a source and a site of perception of signals. Our work aims at understanding the function of cell wall proteins during development. It requires (i) the identification of cell wall proteins and of the corresponding genes, (ii) the following of the dynamics of the cell wall proteome in various physiological conditions, and (iii) functional analyses.

Five topics are presently worked out:
- Structural and functional proteomics
- Structure-function relationships for proteins having domains of interactions with cell wall components
- Lectin-kinase receptors and cell walls ligands
- Spatio-temporal expression of cell wall proteins during development
- Functional analysis of CIII peroxidases during Arabidopsis thaliana development
