Arbuscular mycorrhizal fungi (AMF) contribute to plant health management, especially in bioprotection against soil-borne pests such as root-knot nematodes (Meloidogyne spp.). These worldwide spread pests have a particularly severe impact on vegetable crops. Our aim is to combine AMF and companion plants as agroecological means to reduce...

Les champignons mycorhiziens à arbuscules (CMA) contribuent à la santé des plantes, notamment grâce à leur effet de biocontrôle contre les ravageurs du sol tels que les nématodes à galles (Meloidogyne spp.). Ces parasites ont un impact particulièrement sévère sur les cultures maraîchères. Notre objectif est de coupler les effets de biocontrôle...

The regulation of carbon allocation between photosyn-thetic source leaves and sink tissues in response to stress is an important factor controlling plant yield. Ascorbate oxidase is an apoplastic enzyme, which controls the redox state of the apoplastic ascorbate pool. RNA interference was used to decrease ascorbate oxidase activity in tomato...
