Proteomics is linked to our research projects on plant biology, mainly aimed at understanding the molecular bases of plant responses and those of resistance/tolerance to biotic (pathogens and parasitic plants) and abiotic (water-related) stresses. We are using both experimental model systems (Arabidopsis thaliana, Medicago truncatula), crops (pea, sunflower, wheat, maize) and forest tree species (Oak, Quercus ilex). By studying the plant proteome (mainly in seeds, roots and leaves) we intend to characterise the natural and artificial variability (genotypes, populations, mutants, transgenics) and characterise responses to stresses (differential expression proteomics), bearing in mind both basic as well as applied purposes.

Current research project and recent publications

Functional genomics (transcriptomics and proteomics) to study variability and responses to stresses in forest tree spp. (Quercus ilex, Quercus rubur, Pinus pinaster).

1. Proteomics as a novel approach to study the Q. ilex decay disease.

Proteomics of arbuscular mycorrhizal Vitis vinifera

France/Brazil bilateral project
A two years bilateral project, financially supported by EGIDE-COFECUB/CAPES is aimed at using proteomic tools to better understand the molecular mechanisms of mycorrhizal Vitis vinifera with regards to fungal pathogen attacks

In the frame of the first year exchanges, both practical and theoretical proteomic courses have been organized at the University Federal of Santa Catarina, Florianopolis
