Cultivar resistance is a major asset for the management of crop diseases and can play an important role in agroecological transition. However, the wide deployment of a reduced number of resistance genes can lead to a rapid adaptation of pathogen populations and to a loss of resistance efficiency. The objective of this study was to characterize and...
Phelipanche ramosa is a weed holoparasite which became a major agronomic problem for several crops in France. The yield and quality losses may be complete and lead to the abandonment of crops in the most infested fields. Chemical weed control using synthetic herbicides does not have a direct effect on this weed because the first half of its reprodu...
Bread wheat can be infected and/or contaminated by several genera of mycotoxin producing fungi. In the European Union, several mycotoxins are subject to defined limits for human consumption. Speculation has arisen about the potential higher contamination level of mycotoxins produced by Fusarium species in organic compared to conventional production...
La gestion des plantes adventices constitue une problématique majeure en céréales à paille. Depuis le développement des premiers herbicides de synthèse, ce levier a été largement utilisé à travers le monde, permettant une gestion efficace et peu coûteuse des adventices. Cependant, dans un contexte de réduction des intrants de synthèse, la recherche...
La gestion des adventices constitue une problématique majeure en céréales à paille afin de mener la transition agroécologique de l’agriculture française. Le choix de variétés ayant une capacité de compétition élevée vis-à-vis des adventices a fait l’objet de peu d’investissements et généré peu de résultats probants, notamment du fait de difficultés...
Invasions of new races can have contrasted consequences on populations of Puccinia striiformis f.sp. tritici, causing yellow rust of wheat. For example, the emergence of PstS7 (Warrior race) had major impacts in Europe and in France. By contrast, PstS2 had no impact in this country, while it affected significantly other parts of the world. The obje...

Monitoring spatiotemporal changes in varietal resistance and understanding its drivers seem essential to managing plant diseases but require having access to the genetic basis of disease resistance and to its deployment. In this study, we focused on yellow rust (Puccinia striiformis f. sp. tritici ) for three decades in France, by using field adult...
Phelipanche ramosa is a major weed holoparasite characterized by a broad host range with a suboptimal development on numerous hosts, suggesting inter- or intra-species specificities. Seeds of P. ramosa germinate after exposure to exogenous chemicals exuded by surrounding host roots such as strigolactones, the concentrations of these germination sti...
Rainfed lowland rice fields in northern Togo are increasingly infested by the facultative hemiparasitic weed Rhamphicarpa fistulosa that is widely reported throughout sub-Saharan Africa to be one of the most damaging weeds in rice fields. In this geographical area, some studies have shown that soil characteristics may influence the presence and/or...
Aims: Individual growth constitutes a major component of individual fitness. However, measuring growth rates of herbaceous plants nondestructively at the individual level is notoriously difficult. This study, based on an accurate non-destructive method of aboveground biomass estimation, aims to assess individual relative growth rates (RGRs) of some...
Herbaceous boundaries adjacent to arable fields can deliver ecosystem services not sufficiently provided at the field scale, as well as disservices such as increased weed pressure. The levels of services and disservices depend on the management regime implemented in these boundaries. Our study was conducted in Western France, where herbaceous bound...
Un modèle a été réalisé pour évaluer l’impact des pratiques agricoles sur la diversité des prairies. Pour tester les prédictions d’un modèle théorique d’écologie, le modèle d’équilibre dynamique, nous avons suivi 18 prairies permanentes du Massif central aux pédoclimats et modes de gestion variés. Nous avons mis en évidence une diminution de la ric...
Résumé
La longévité commerciale de certaines variétés de blé tendre pourrait partiellement s’expliquer par la présence de résistances durables à la rouille jaune, une maladie importante en France. Pour tester cette hypothèse et identifier des résistances durables, nous nous sommes focalisés sur les épidémies des dernières décennies dans le Bassin P...
Management of biotic interactions has been recognized as a potential substitute for costly agrochemical inputs. Competition is one of the most important biotic interactions known to regulate populations and govern species assemblages. However, although theoretical and empirical work has been produced on competition, in situ experimental evidence is...
Road verges provide a refuge for numerous plant species, especially in agroecosystems characterized for decades by a general decline in semi-natural habitats and edge density. Beyond the influence of present landscape structure on the local structure and composition of plant communities, past landscape structure could also have a substantial effect...
The present document details how the Wheatamix consortium, inspired by ecological experiments exploring relationships between plant biodiversity and ecosystem functioning (e.g. the Jena experiment Weisser et al. 2017), selected bread wheat (Triticum aestivum L.) lines, phenotyped them across a range of functional traits and used this information to...
Key message:
We present and highlight a partitioning procedure based on the Rao quadratic entropy index to assess temporal in situ inter-annual varietal and genetic changes of crop diversity. For decades, Western-European agroecosystems have undergone profound changes, among which a reduction of crop genetic diversity. These changes have been high...
Phelipancheramosa is a major root-holoparasitic damaging weed characterized by a broad host range, including numerous Fabaceae species. In France, the agricultural threat posed by P. ramosa has increased over two decades due to the appearance of a genetically differentiated pathovar presenting a clear host specificity for oilseed rape. The new path...
QuestionsManagement practices implemented on road verges are partly established to preserve biodiversity in agricultural landscapes. Their evaluation was primarily based on the analysis of the taxonomic structure and composition of communities. What is the relationship between management practices and the functional characteristics of road-field pl...
We examined the commercial life cycle of varieties of arable crops that could bring a better understanding of the drivers of their commercial success. In the current study, we propose indicators to describe the commercial life cycle of a variety and test their relevance on a case study centered on bread wheat varieties in France. We focus on yellow...
A null model randomizing semi-quantitative multi-classes (or ordinal) data by swapping sub-matrices while both the row and the column marginal sums are held constant.
Integrating principles of ecological intensification into weed management strategies requires an understanding of the many relationships among weeds, crops and other organisms of agro-ecosystems in a changing context. Extensively used during the last two decades in weed science, trait-based approaches have provided general insights into weed commun...
An in-depth analysis of the spatio-temporal evolution of crop diversity in agricultural landscapes is necessary to provide insights on how to improve the resilience of agroecosystems to climate instability and new pest pressures by increasing in situ crop diversity, while promoting a greater sustainability of agriculture. However, most of the indic...
Branched broomrape (Phelipanche ramosa (L.) Pomel) is a holoparasite weed causing significant yield losses on several crops, especially in France on winter oilseed rape fields. The ability to induce germination of seeds of branched broomrape, variable between host species, represent an important information to identify the status of weed species pr...
Quels ont été les principaux facteurs sociotechniques, économiques, organisationnels et réglementaires susceptibles d’avoir influencé la diversité cultivée au cours des dernières décennies ? Dans cet article, nous présentons les résultats d’une réflexion sur le blé tendre, espèce cultivée d’intérêt économique majeur. Nous y présentons l’évolution d...
Phelipanche ramosa is a generalist parasitic weed known to cause yield losses in various crops, especially in winter oilseed rape, its new preferred host in France. This parasitic plant is also able to complete its life cycle on many Brassicaceae weeds, which are thus important alternative hosts. We studied a set of 14 common Brassicaceae weeds and...
Transportation infrastructures are usually considered as damaging for biodiversity because of their barrier effect. However, through their rights-of-way, transportation infrastructures can also enhance biodiversity as corridor or refugia for many species. These contradictory effects of transportation infrastructures on biodiversity have been studie...
QuestionsPlant communities of road verges adjoining arable fields are often managed for conservation purposes. How do the diversity and composition of plant communities differ within and between berms, embankments and field margins? What is the influence of management practices on the diversity and composition of plant communities within and betwee...
How weed communities assemble represents one the key issues of weed science. For a decade, functional approaches have been applied to investigate the processes that govern weed community assembly. In most previous studies, trait values have been generally averaged over multiple populations and habitats. Consequently, conspecifics display similar tr...
Aims
In agro-ecosystems, crop types, i.e., the crop species and its associated agricultural practices, have been shown to influence the taxonomic as well as functional composition of weed communities. However, the processes underlying weed community assembly within a crop type are poorly understood, especially regarding the contributions of local f...
Malgré de nombreux travaux menés, les mécanismes d’assemblage des espèces adventices en communautés restent à identifier. Or cette compréhension est cruciale pour concevoir des stratégies de gestion permettant de préserver la biodiversité des plantes adventices tout en maintenant la production agricole. Ce travail de thèse avait pour objectif de co...
Background and aims – Recent methodological and theoretical advances in community ecology have
allowed more robust exploration of complementary facets of biodiversity in plant communities. Focusing
on semi-natural permanent grasslands of the French Jura Mountains, we assessed how taxonomic,
phylogenetic and functional diversity metrics vary among t...
Arable weeds are a key component of the biodiversity of agroecosystems, but have faced a marked decline due to agricultural intensification. Recently, the crop edge has been considered as a potential refugia for many species. Indeed, weed species richness and abundance are higher in the crop edge than in the field margin and the field core. In this...
