Discovery of evolutionary conserved genes governing leaflets formation in eudicots plants
group of Patrick Laufs have identified genes of the
regulation network involved in leaflet formation during leaf development.
This work has been published in Science
(19 december 2008) together with a group from the University of Oxford.
Works on plant development, initiated in the group for more than ten years, has shown that the NAM/CUC regulatory genes’ family is involved in boundary domains setup between leaves, during their initiation at the tip of shoots in the cruciferous model plant Arabidopsis thaliana. Serrations formation on its simple leaves is also controlled by a member of this regulatory gene family. In Arabidopsis, a natural variation can be observed: leaf margins are more or less incised depending on the gene pool of the wild type plant. The scientists hypothesized that some of these regulators could play a role in leaflets formation in plants with compound leaves.
Comparative study of
leaf development in four plants harbouring compound leaves: columbine
(Ranunculaceae), tomato (Solanaceae), cardamine (Brassicaceae) and pea
(Fabaceae) showed that NAM/CUC3 genes control serration and leafletformation.

Loïc Lepiniec received the price of plant biology from Académie des sciences for hisworks in integrative biology
Project leader Inra at the Seed Biology Laboratory from the IJPB and head of the Plant Biology Departement, Loïc Lepiniec was honored the 25th november 2008 by the Octave Mirbeau et Valentine Allorge price. This price of plant biology from the Académie des sciences awarded every four years comes to reward its works led since 1996 on the genetic determinism and molecular of the seed quality in the model plant Arabidopsis thaliana.

Georges Pelletier organized the conference « Aspects of genetics and plant breeding » the 25th march 2008 for his medals ceremony of “insignes de la Légion d’honneur”, l’INRA, Versailles
This ceremony initiated by INRA honour an
outstanding scientific who produced pioneering contributions of first
order to plant breeding field (haploid plant achievement, device of trangenesis
techniques, development of research on the model plant Arabidopsis). This
conference recounted some of the major progress in the plant genetics
field and its application in plant breeding during the last years (programme).
History of this scientific field was recalled as an introduction by Georges
Pelletier. Guy Riba, Deputy Director General, in charge of scientific
programmes, resources and evaluation, opened the ceremony. He emphasized
the major role of Georges Pelletier in new knowledge acquiring and economic
impact of his scientific work (hybrids of rape and cabbage, haploid* asparagus).
The ceremony was closed with the prizegiving by Jean-Claude Mounolou from
d’Agriculture de France” (see

FLAVO WORKSHOP 2008 :
Flavonoids, Diet and Human Health
June 19th 2008, INRA-IJPB, Versailles, France
FREE Registration (On-line registration is mandatory due to limited seats and open until June 12)
Preserving human health by improving plant food has become a major societal issue.
FLAVO is a European Commission-funded research project aiming at the production of the knowledge and tools necessary to develop healthier and consumer-desirable fruits, vegetables and derived foods/beverages containing optimal levels of flavonoids.
Flavonoids are polyphenolic compounds found in fruits and vegetables that may protect against cancer and cardiovascular diseases and extend lifespan. FLAVO is focused on crops and model plants (e.g. grape, apple, and strawberry) and their derived products (wine, fruit juices and jams). These fruits are rich sources of flavonoids and their derived products are largely consumed.
The development of plant food with specific flavonoid contents is expected to have a direct impact on food quality and human health, to offer new market opportunities, to increase thecompetitiveness of the Agri-Food sector and to reduce health care expenses.
workshop will present the results obtained within FLAVO and the interest
of using flavonoids to develop functional foods. More largely, it will
also address industrial applications, market opportunities and consumer
attitudes towards functional foods and beverages. These topics will be
structured into 4 themes:
This workshop will bring together leading researchers and representatives of the academy, consumer organisations,professional federations, unions of crop breeders, agro-food industries and mass press.
