INRAE presentation

The French National Research Institute for Agriculture, Food, and the Environment (INRAE) is a public research establishment under the dual authority of the Ministry of Agriculture and the Ministry of Research.

INRAE is recruiting researchers by open competition and offering permanent position.

It is a major player in research and innovation created on 1st of January 2020. INRAE is a research institute resulting from the merger of INRA and IRSTEA. It is a community of 12,000 people with more than 200 research units and 42 experimental units located throughout France.

The institute is among the world leaders in agricultural and food sciences, in plant and animal sciences, and is 11th in the world in ecology and environment. INRAE’s main goal is to be a key player in the transitions necessary to address major global challenges. In the face of the increase in population, climate change, scarcity of resources and decline in biodiversity, the institute develops solutions for multiperformance agriculture, high quality food and sustainable management of resources and ecosystems.

Work environment, missions and activities

The Seapag team of the UMR AGAP is developing a scientific project on genetics and varietal innovation in citrus fruits. It is strongly involved in the development of citrus genomics and phylogenomics in order to decipher the complex phylogenomic structures of cultivated forms and their link with phenotypic variability, and the analysis of the physiological, genetic and genomic bases of traits of interest in citrus fruit.
Quality of the fruits as well as the adaptation of the rootstocks is at the heart of the citrus improvement project led by the team and stakeholders. Thus, a multidisciplinary Feder project "InnovAgrumes" offers the Corsican citrus industry a new range of varieties of small-fruited citrus fruits, in a co-construction process with socio-economic and academic partners (notably the University of Corsica).
Work on the modulation of the graft phenotype by the rootstock to compensate for the impact of climate change is also underway. In support of these innovation projects, QTL analyses and genomic selection models should be developed on the quality of small citrus fruit and its modulation by the rootstock. Today, little is known about the genetic basis for the variability of pomological and organoleptic characteristics (juice, sugar, organic acids, carotenoids and polyphenols) and adaptation.
The hired researcher will be more particularly positioned at the interface between genomic studies and quantitative genetics. First, the hired researcher will exploit the massive data from the France-Genomics DynaMo project, including complete resequencing on a diversity collection and GBS on various diploid and triploid recombinant populations, in the field evaluation phase at the San Giuliano station. They will enable it to develop association studies and set up a genomic selection project aimed at accelerating varietal selection. The exploitation of these massive data for association studies with phenotypic variability in a genomic selection perspective is a major challenge for the team for an ambitious scientific valorization of the great genetic diversity managed and characterized in the CRB Citrus and in the multiple segregated populations. Strong and regular interactions will be woven with other researchers in citrus genetics/genomics and physiology based in Montpellier and the West Indies. Beyond citrus research issues, the(a) CR will be called upon to contribute to the UMR AGAP working group on quantitative genetics and selection, including genomic selection.

Training and skills

PhD or equivalent

Candidates must have a PhD or equivalent.
The hired scientist will need to have a sound background in quantitative genetics, genome functionning and biostatistics or bioinformatics with genetic specialization. Good statistical knowledge, particularly bayensian statistics with programming concepts, R Software and modelisation are required. An experience in genomic data analysis and/or Gwas approaches will be strongly appreciated.
Being fluent in English and a long duration international experience are recommended: hired scientists who will not have such previous experience will have to do a stay abroad after their intership year.
