Intensive management negatively impacts field margin ecosystem service indicators at both field and landscape levels. [PDF]

Ecol Appl
Abstract Vegetated field margins generally increase plant biodiversity and connectivity in agricultural landscapes. They can deliver ecosystem services, such as providing food and shelter for insects, or maintaining biotic regulation. But they can also represent a risk, for example by hosting competitor plants or cultivated crop pests. In this work, we

Alleviation of water-deficit inhibition of plant growth by rhizosphere microbiota conditioning. [PDF]

New Phytol
Summary Rhizosphere microbiota conditioning is a promising strategy to enhance plant growth. We conditioned the rhizosphere microbiota of Brassica juncea to water deficit to assess its impact on plant growth. In a glasshouse, plants were first grown under well‐watered conditions, then exposed to moderate (MD, pF = 2.3) or extreme (ED, pF = 3.5) water ...

Structural conservation of WEE1 and its role in cell cycle regulation in plants

Scientific Reports, 2021
The WEE1 kinase is ubiquitous in plant development and negatively regulates the cell cycle through phosphorylations. However, analogies with the control of the human cell cycle by tyrosine- (Tyr-) phosphorylation of cyclin-dependent kinases (CDKs) are ...

Drivers of Viral Prevalence in Landscape-Scale Pollinator Networks Across Europe: Honey Bee Viral Density, Niche Overlap With This Reservoir Host and Network Architecture. [PDF]

Ecol Lett
Viral spill‐over from honey bees is a potential threat to wild pollinators. We used causal modelling approaches to detect the main drivers of spill‐over. Honey bee viral density, niche overlap with honey bees, urbanisation and plant‐pollinator network structure all played an important role in the transmission of BQCV, DWV‐A and DWV‐B.

Crises environnementales et sanitaires : des maladies de l’anthropocène qui appellent à refonder notre système alimentaire

Cahiers Agricultures, 2020
Depuis le milieu du XXe siècle, les impacts des activités humaines sur les écosystèmes sont croissants. À l’érosion de la biodiversité et au dérèglement climatique, ainsi qu’au développement de maladies chroniques que constituent l’obésité et le diabète,

Tillage intensity and pasture in rotation effectively shape soil microbial communities at a landscape scale

MicrobiologyOpen, 2019
Soil microorganisms are essential to agroecosystem functioning and services. Yet, we still lack information on which farming practices can effectively shape the soil microbial communities.

Identification of Novel Sources of Resistance to Seed Weevils (Bruchus spp.) in a Faba Bean Germplasm Collection

Frontiers in Plant Science, 2019
Seed weevils (Bruchus spp.) are major pests of faba bean, causing yield losses, and affecting marketability. Our objective was to identify stable sources of resistance to seed weevil attacks, determine the climatic factors that most influenced its ...

Biogeographical patterns of the soil fungal:bacterial ratio across France

mSphere, 2023
Soils are one of the major reservoirs of biological diversity on our planet because they host a huge richness of microorganisms. The fungal:bacterial (F:B) ratio targets two major functional groups of organisms in soils and can improve our understanding ...
