Description du projet
Renforcer la biosécurité des arbres en Europe
Le changement climatique expose les forêts européennes à un risque accru de pathogènes invasifs et de maladies infectieuses. Cette situation a des répercussions sur la bioéconomie forestière, qui peut contribuer à l’atténuation du changement climatique. Il est primordial de trouver de nouvelles solutions pour protéger les forêts et maintenir la biosécurité sans faire appel à des méthodes chimiques. Dans ce contexte, le projet RESISTREE, financé par l’UE, a pour ambition de pallier les lacunes de nos connaissances concernant la phase d’établissement des invasions biologiques. Il se concentrera sur les espèces principales de hêtres européens. Ce projet permettra d’améliorer notre compréhension des processus d’invasion et débouchera sur des découvertes révolutionnaires concernant les moyens de renforcer la biosécurité et la prévention des maladies chez les plantes sans recourir à des produits chimiques.
Objectif
Invasive alien pathogens and emerging infectious diseases are an unprecedented threat to the capacity of European forests to supply the growing bioeconomy with renewable biomass, carbon sequestration and other essential ecosystem benefits. To strengthen the biosecurity against these pathogens, new, science-based and socially acceptable forest protection solutions need to be developed. The research in RESISTREE will target central knowledge gaps related to a crucial phase of a biological invasion, the establishment phase. Specifically, RESISTREE will deliver in-depth information about the host phenotypic traits and associated mycobiome that can suppress establishment of the invasive Phytophthora-species (Oomycetes) on one of the key stone species of European forests, the European beech (Fagus sylvatica L.). We will test hypotheses about (1) H1 - Endophyte assemblages differ between healthy and Phytophthora-infected beech trees; (2) H2 - Certain endophytic fungi (individual species or groups) limit the growth of Phytophthora-species through different mechanisms; (3) H3 - Lesion formation in beech tissues depends on the quality or quantity of endophytic infections in the tissue; and (4) H4 - Phytophthora root infection influences the growth and morphology of seedlings before visible symptoms (chlorosis,lesions) appear. RESISTREE combines theory and methods from ecology, cell biology, mycology and forest pathology, resulting in an original, multidisciplinary research with high potential for ground-breaking findings. RESISTREE will promote transfer of knowledge between academia and the private sector, resulting in an interdisciplinary project. RESISTREE adheres to priorities of the H2020 program, and follow the European recommendations included in the Directive 2009/128/EC, which calls for non-chemical methods of plant protection.
