Research in Biodiversity and Polyploidy (BP) team

Research in Biodiversity and Polyploidy (BP) team
The mission of the BP team is to describe, preserve, and classify germplasm, and to understand the genetic mechanisms that are involved in the stabilization of polyploid genomes and in the regulation of genetic recombination between relatives of a species.

The final aim of these research activities is to optimize the use of genetic diversity in cultivated polyploidy species, such as potato. BP runs the Biological Resources Center BrACySol (“Centre de Ressources Biologiques”), located in Ploudaniel, and which preserves germplasm collections of potato and its relatives, Allium (shallot and garlic), Cynara (artichoke and cardoon), and Brassica (rape and cabbage).

In addition to activities related to the preservation of healthy plant material, research on potato and its relatives enables to:

  • Understand the genetic diversity and genetic structure using molecular markers;
  • Develop new tools for long-term preservation of genetic material (cryoconservation of meristems)
  • Phenotype plant material as part of an agreement with the ACVNPT (Association of French Potato Breeders)
  • Introgress traits of interest and supply improved germplasm to members of the ACVNPT.
