Evaluation of viticultural practices on arbuscular mycorrhizal fungi associated with grapevine
Arbuscular mycorrhiza, a mutualistic symbiosis established between plants and arbuscular mycorrhizal fungi (AMF), provides many ecosystem services such as improved soil structure, increased plant growth and nutrition, and improved tolerance to biotic and abiotic stresses. However, intensive agricultural practices and the use of phytosanitary products as for example herbicide and fungicides, have a strong impact on communities of soil microorganisms, including arbuscular mycorrhizal fungi, as well as on biological mechanisms within the ecosystem. This thesis wotk is part of the European Biovine project supported by the European Commission through the CORE Organic Cofund. The aim of this rese…
The arbuscular mycorrhizal transportome, what next!
International audience; Understanding how arbuscular mycorrhizal (AM) symbioses establish and function is one of the most important current challenges in microbial ecology. Despite the fact that the AM symbiosis requires some complex and fine molecular tuning among symbionts in order to take place, both partners benefit from each other in a number of ways. For instance, the availability, uptake and exchange of nutrients in this biotrophic interaction are key factors driving plant growth and modulating biomass allocation. This underground trade is regulated by both plant and fungal transport components [1], as for instance the long distance transport of photosynthates from leaves towards col…
Les couverts végétaux. Un atout majeur pour réduire les intrants de synthèse et augmenter les services écosystémiques au vignoble
International audience; De manière générale, un couvert végétal se définit par une espèce ou une communauté d’espèces végétales recouvrant le sol de manière permanente ou temporaire. L’agriculteur a la possibilité de semer ces couverts, selon un choix raisonné, ou bien de laisser la végétation spontanée se développer. Il existe 3 types de couverts semés avec des objectifs différents pour l’exploitant : le couvert hivernal, installé pour faire face au phénomène d’érosion du sol important pendant cette période de repos végétatif ; les engrais verts, installés avec l’objectif d’amender naturellement la parcelle, en détruisant et en enfouissant les résidus du couvert qui libèrent ainsi de la ma…
BioVine project - Increase plant health through mycorrhizal fungi
National audience; Organic vineyards still rely on large external inputs to control harmful organisms. BIOVINE will develop natural solutions based on plant diversity to control pests and reduce pesticide dependence. The capacity of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures like vineyards do not exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased plant diversity within (e.g. cover crops) and/or around vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes, fungi, nematodes), and foliar pathogens.…
