• Symposium at the Salon International de l'Agriculture 2015: soils

    The 68th United Nations General Assembly declared 2015 as the International Year of Soils.  INRA thus devoted its symposium at the Salon International de l’Agriculture to "Soils: their services and uses".

    The symposium was broadcast via direct video streaming and a live debate on this web page and via @Inra_France and @Inra_Intl with the hashtag #IYS2015.

  • Live at 2.30 pm: Where jobs are born, key advice to candidates

    Students, young grads, jobseekers: INRA hosted a conference on jobs and careers in the Institute at its dedicated stand at the International Agricultural Show Friday, 27 February from 2:30 pm to 3:30 pm. 
    The conference was broadcast via direct video streaming and a live debate on this web page and via @Inra_Intl with the hashtag #HR.

  • Meetings and symposium at SIA 2015

    To mark the Salon International de l'Agriculture 2015, INRA is organising eight meetings for its partners, focused on the topics addressed by its metaprogrammes.  
    In this International Year of Soils, the subject of the symposium on 24 February is: "Soils: their services and uses".
    Finally, the general theme of INRA's stand this year is "Climate change: understanding it, adapting to it and innovating".

  • INRA-CIRAD: a long tradition of collaboration

    On Friday, 6 February 2015, Michel Eddi, CIRAD President, and François Houllier, INRA President, signed an agreement to establish a joint international relations unit. The two spoke about their long history of working together and outlined the new unit’s international aims.

  • Sounding the alert: forests face the threat of climate change

    International experts have issued a joint declaration to raise public awareness about the possible widespread forest tree deaths due to climate change and the resulting social and ecological implications.

  • How synthetic biology could benefit from the social sciences

    Create life? To what end? Is such a goal possible or even desirable? This report details studies being carried out by INRA social scientists that deal with synthetic biology; their research is raising important questions.

  • Scrapie could breach the species barrier

    INRA scientists have shown for the first time that the pathogens responsible for scrapie in small ruminants (prions) have the potential to convert the human prion protein from a healthy state to a pathological state. In mice models reproducing the human species barrier, this prion induces a disease similar to Creutzfeldt-Jakob disease. These primary results published in Nature Communications on 16 December 2014, stress the necessity to reassess the transmission of this disease to humans.

Unearthing the Roots of Fungal Symbioses

To understand the bases of mutualistic symbiosis between soil mycorrhizal fungi and plants, an international consortium of researchers conducted the first broad, comparative phylogenomic analysis of mycorrhizal fungi.

Understanding the mechanism behind dominant and recessive gene expression

Why are some genes dominant while others are recessive? After nearly a century of investigation, hypotheses and experiments, we finally understand the inner workings of this fundamental biological phenomenon.

Phytomicronutrients: a better understanding of their biological effects

Since 2005, more than 60,000 scientific articles have been published on flavonoids. A growing number of studies are investigating the nutritional benefits of the phytomicronutrients in our food. Phytomicronutrients are found primarily in fruits and vegetables, but also in tea, coffee, wine, nuts, and brown rice.
