Validation of a set of reference genes to study response to herbicide stress in grasses
2012
Abstract Background Non-target-site based resistance to herbicides is a major threat to the chemical control of agronomically noxious weeds. This adaptive trait is endowed by differences in the expression of a number of genes in plants that are resistant or sensitive to herbicides. Quantification of the expression of such genes requires normalising qPCR data using reference genes with stable expression in the system studied as internal standards. The aim of this study was to validate reference genes in Alopecurus myosuroides, a grass (Poaceae) weed of economic and agronomic importance with no genomic resources. Results The stability of 11 candidate reference genes was assessed in plants res…
A European multicentre evaluation of detection and typing methods for human enteroviruses and parechoviruses using RNA transcripts
2020
Polymerase chain reaction (PCR) detection has become the gold standard for diagnosis and typing of enterovirus (EV) and human parechovirus (HPeV) infections. Its effectiveness depends critically on using the appropriate sample types and high assay sensitivity as viral loads in cerebrospinal fluid samples from meningitis and sepsis clinical presentation can be extremely low. This study evaluated the sensitivity and specificity of currently used commercial and in‐house diagnostic and typing assays. Accurately quantified RNA transcript controls were distributed to 27 diagnostic and 12 reference laboratories in 17 European countries for blinded testing. Transcripts represented the four human EV…
La céramique médiévale et moderne (12e - 17e siècles) en Bourgogne : production, consommation, diffusion. Projet Collectif de Recherches 2018-2021. B…
2022
Le programme collectif de recherches intitulé « La céramique médiévale et moderne (12e - 17e siècles) en Bourgogne : production, consommation, diffusion » a entamé ses travaux en 2018, pour une programmation sur quatre années, jusqu’en 2021. Il a pour objectifs de détecter les sites de fabrication potière médiévaux et moderne en Bourgogne, d’en caractériser la production et d’évaluer leur diffusion sur les sites d’habitat.Le nombre de chercheurs associés au programme, rattaché à l’UMR ARTEHIS (Dijon), varie légèrement d’année en année mais tourne en moyenne autour d’une douzaine (11 en 2018, 13 en 2019, 14 en 2020 et 2021). Ils sont issus de diverses institutions (Inrap, Etat, privé, UMR, b…
Neolithic Human Societies and Woodlands in the North-Western Mediterranean Region: Wood and Charcoal Analysis
2017
An overview of woodland history in the north-western Mediterranean region, based on charcoal analysis (Anthracology) from Mesolithic and Neolithic sites, is proposed for the Mediterranean areas of France, Spain and Portugal. The taxonomic identification of charcoal fragments and the diachronic variations of taxa frequencies provide, for each settlement, an accurate image of the local vegetal cover. During the end of the last glaciation, beginning of the Holocene, vegetation dynamics reflects the evolution of climatic and geographic conditions. Any potential ecological impact by hunter-fisher-gatherer communities (Mesolithic) remains invisible; the same comment applies to the farming-herding…
What impact does man have on the soils of the Pasques woods?
2022
About twenty kilometers north-west of Dijon, 26 deserted sites, ranging from Antiquity to the late Middle Ages, are listed in the woods of Haut Val Suzon on the margins of the finages of Saint-Martin-du-Mont, Saint -Seine-l'Abbaye, Val-Suzon, Panges and Pasques. Remarkably, the Bois de Pasques brings together 14 of them. In this small space, there are 2 ancient sites, 2 from the High Middle Ages, 1 from the 11th-12th century and 2 from the 13th century, one of which was recently destroyed and one still active but moved during Modern Times. To these are added 7 habitats established, occupied and deserted during the 14th century. Eleven sites were explored by soundings to ensure their dating …

History and environmental impact of mining activity in Celtic Aeduan territory recorded in a peat-bog (Morvan – France)
2004
International audience; The present study aims to document early mining and smelting activities by means of geochemical and pollen analyses performed in a peat-bog core collected around the Bibracte oppidum (Morvan, France), the largest settlement of the great Aeduan Celtic tribe (ca 180 BC -25 AD). The anthropogenic Pb profile indicates local mining operations starting from the Late Bronze Age, ca cal. 1400-1300 BC. Lead inputs peaked at the height of Aeduan civilization, and then decreased after the Roman conquest of Gaul, when the site was abandoned. Other phases of mining are recognised from the 11th century to Modern Times. They have all led to modifications in plant cover, probably re…
