La plateforme GenoSol de l’UMR Agroécologie de l’INRA de Dijon est une structure unique en Europe, centrée sur la (micro)biologie des sols. Ses missions s’articulent autour de trois activités principales : un Conservatoire des Ressources Génétiques Microbiennes, une Plateforme Technique de caractérisation moléculaire du métagénome microbien, un Système d’Information sur la diversité microbienne des sols et de l’environnement. Depuis 2015, la Plateforme GenoSol est certifiée ISO 9001 pour le Conservatoire des Ressources Génétiques Microbiennes.

The eDNA platform

6 Avril 2017,

Publié par Bioécologie

This technical platform has been set up to allow ecologists to perform large-scale analysis of environmental DNA via a metabarcoding approach. DNA metabarcoding refers to high throughput DNA-based identification of multiple species from environmental DNA. The main applications consist in diet analysis from feces, in biodiversity assessment using soil or water samples, and in palaeo-environment reconstruction using lake sediments and permafrost samples.

The eDNA platform is composed of three pre-PCR extraction rooms dedicated to feces, soil, and ancient DNA, and to several post-PCR rooms dedicated to the purification and the titration of PCR products. The next generation sequencing on Illumina platforms (HiSeq or MiSeq) is outsourced.

Research  policy observers  are increasingly concerned  about the potential  impact  of current  academic working conditions on mental health, particularly in PhD students. The aim of the current study is three-fold. First, we assess the prevalence of mental health problems in a representative sample of PhD students in Flanders,  Belgium  (N = 3659). Second, we compare  PhD students  to three other samples: (1) highly educated in the general population (N = 769); (2) highly educated employees (N = 592); and (3) higher education students (N = 333). Third, we assess those organizational factors relating to the role of PhD students that predict mental health status. Results based on 12 mental health symptoms (GHQ-12) showed that 32% of PhD students are at risk of having or developing a common psychiatric disorder, especially depression. This estimate was significantly higher than those obtained in the comparison groups. Organizational policies were significantly associated with the prevalence  of mental health problems. Especially work family interface, job demands  and job control, the supervisor’s leadership  style, team decision-making culture, and perception of a career outside academia  are linked to mental health problems.
