Evolution of herbicide resistance in mugwort (Ambrosia artemisiifolia L.): search for genetic determinisms and application to molecular diagnosis

2022

Common ragweed (Ambrosia artemisiifolia L.), a particularly troublesome and allergenic weed, is mainly controlled in agricultural fields using ALS inhibitor herbicides. Recent cases of herbicide resistance have been reported in France and are jeopardising the efficacy of this mode of action. Both target site resistance (TSR, structural mutation in ALS gene) and non target site resistance (NTSR, regulatory and/or structural mutations in secondary metabolism) are involved. The fundamental aim of this work was to identify the genetic determinisms of resistance to ALS inhibitors that have evolved in common ragweed populations in France. As an applied objective, this work also aimed to prepare t…

Runs of homozygosity in the Italian goat breeds: impact of management practices in low-input systems

2021

Abstract Background Climate and farming systems, several of which are considered as low-input agricultural systems, vary between goat populations from Northern and Southern Italy and have led to different management practices. These processes have impacted genome shaping in terms of inbreeding and regions under selection and resulted in differences between the northern and southern populations. Both inbreeding and signatures of selection can be pinpointed by the analysis of runs of homozygosity (ROH), which provides useful information to assist the management of this species in different rural areas. Results We analyzed the ROH distribution and inbreeding (FROH) in 902 goats from the Italia…

Sport commitment and adherence: A social-cognitive analysis. (Compromiso deportivo y adherencia: Un análisis cognitivo social).

2011

Abstract Statement of problem: This study aimed to analyse the ability of a model based on achievement motivation and self-determination theories to predict adherence to competitive sport. This model incorporated commitment as predictor of adherence. A prospective study was performed with a sample of 302 handball players aged between 14 and 18 years. Structural equation modelling gave support to the model proposed. It was verified the sequence of relationships between perceptions of coach-created mastery climate, psychological needs, self-determined motivation, commitment, and adherence. The major contribution of the study was to confirm a motivational model of adherence based on social-cog…

Extending existential feeling through sensory substitution

2023

AbstractIn current philosophy of mind, there is lively debate over whether emotions, moods, and other affects can extend to comprise elements beyond one’s organismic boundaries. At the same time, there has been growing interest in the nature and significance of so-called existential feelings, which, as the term suggests, are feelings of one’s overall being in the world. In this article, I bring these two strands of investigation together to ask: can the material underpinnings of existential feelings extend beyond one’s skull and skin? To begin, I introduce and adopt a componential-systemic view of extended affectivity. In doing so, I specify the vehicle externalist criteria for extension em…

Legumes in 21st century Europe: present and future importance in agri-food systems? New challenges for reseach.

2013

Intensification of agriculture since 1950 has globally led to the decline of grain legume crops, which currently represent less than 3 % of arable crops in France and Europe. Nevertheless, legumes have several major assets (i) as plant proteins for animal feed and human food and (ii) as plants fixing atmospheric N2 and thereby saving nitrogen inputs in cropping systems, and (iii) as diversification crops. The analysis of forage and grain legume producing systems in France showed that the dominant system results in a lock-in of the different factors limiting legume insertion into the current systems. But legumes could have a major role to play in the agroecological transition towards more su…

Modelling cropping system effects on branched broomrape dynamics in interaction with weeds

2018

International audience; Branched broomrape, Phelipanche ramosa (L.) Pomel, is a parasitic plant which infects many crop and weed species. As a holoparasite, it entirely relies on host resources to survive and reproduce. It is a major pest in oilseed rape in France. Its management has to be thought as a part of the overall weed management because infected weeds either must be killed to limit crop infection or can be used to stimulate suicidal parasite germinations. In order to design efficient pest management strategies, we modelled the effects of cropping systems on P. ramosa dynamics in interaction with weeds in a model called PHERASYS. PHERASYS functions and parameters were based on the l…
