Arabidopsis thaliana

Arabidopsis thaliana is a small flowering plant (angiosperm) that belongs to the Brassicaceae family (cabbage, mustard, rapeseed, radish…). It is widely used for studying plant genetics, evolution and development. The small size of the plant and its rapid lifecycle are particularly convenient for research. The small size of its genome (first plant genome sequenced in 2000), simple genetic transformation using Agrobacterium tumefaciens, and large public mutant collections make it a valuable model for understanding the genetic and molecular biology of flowering plants.

 


A moss

 

The moss Physcomitrella patens belongs to one of the most ancient group of land plants and is used for studies of plant evolution. This moss presents a high level of homologous recombination when transformed and is the only plant where gene targeting is feasible. We also study it as a model photosynthetic eukaryote for the regulation of growth and biofuel production. We can grow it in vitro throughout its complete life cycle.

For specific projects we are also using photosynthetic bacteria or crop plants such as tomato.​.
