National Institute for Agricultural Research

The National Institute for Agricultural Research (INRA) is a public research institution under the joint authority of the Ministry of Higher Education and Research and the Ministry of Agriculture, Agrifood and Forests. The research conducted at INRA concerns agriculture, food, nutrition and food safety, environment and land management, with particular emphasis on sustainable development.

The project will more particularly involve a research unit of the Poitou-Charentes Centre of INRA. This research unit, UR P3F (Unité de Recherches Pluri-disciplinaire Prairies et Plantes Fourragères) is committed in research about genetics, breeding and eco-physiology of grassland species. It gathers scientists from the Plant Science department of INRA (BAP), which includes plant genetics and breeding, and from the Environment and Agronomy department (EA). The main focus of this unit is the improvement of services provided by pluri-specific grasslands in the context of an agro-ecological agriculture. Within this frame, UR P3F develops investigations combining skills in quantitative and population genetics, in plant breeding and genetic resource conservation and in plant eco-physiology and agronomy. The project will involve UR P3F scientists from the BAP department (Jean-Paul Sampoux, Isabelle Litrico and Philippe Barre) and a scientist from the EA department (Didier Combes).

This FACCE-JPI project will contribute to an INRA collaborative initiative approved by the INRA meta-programme AAFCC (Adapting Agriculture and Forestry to Climate Change). This collaborative initiative, named CLIMAGIE, is led by Jean-Louis Durand, head of UR P3F. It gathers several INRA units to join their efforts in contributing to improve adaptation and resilience of grasslands in the face of climate change.

INRA UR P3F hosts a genebank for grasslands species which maintains the national collections for these species in collaboration with French plant breeding companies. This genebank has received seal of approval and grant for entering the French network of Biological Resource Centres managed the IBISA GIS. It will provide part of the accessions required for the genebank set. Staff from the genebank will also contribute their experience to collect new genetic material for the in situ set. UR P3F benefits of large acreages of experiment fields and has high skill staff for carrying out fine in-field phenotypic records, including eco-physiological measurements such as canopy temperature. UR P3F has facilities to perform NIRS (Near Infra-Red Spectrometry) measurements of nitrogen content and quality components of grass forage such as water soluble carbohydrates. UR P3F holds a laboratory able to carry out various genotyping methods that will carry out the DNA extractions and check of DNA quality planned for INRA in the project.

INRA UR P3F will use an INRA platform at UMR Ecology and Ecophysiology of Forests (UMR 1137, Nancy) for nitrogen content and 13C discrimination assessments. INRA sequencing platforms of Evry (LPGV) and Clermond-Ferrand (GENTYANE) will be used for the sequencing tasks assigned to INRA in the project. The INRA bioinformatics platform of URGI (Evry), maintaining a multispecies centralized information system, will be used for repository and share of data of the project. The UMR Ecology and Ecophysiology of Forests (Nancy) holds an extended database system for environmental (and notably climatic) data storage managed by Vincent Badeau who will be the leader of two tasks in the project. This facility will be used to provide environmental data for the project.
