Description du projet
Tester la tolérance des plantes aux métaux lourds
Les agriculteurs et les décideurs politiques commencent à repenser certaines pratiques agricoles en raison de la libération de produits agrochimiques dans l’environnement, causant une contamination des sols par des métaux lourds. Cet important problème environnemental entraîne des pertes à court terme dans la production agricole, avec des répercussions à long terme sur l’environnement et la santé. Le projet BACTEPEA, financé par l’UE, ciblera les interactions moléculaires entre une actinobactérie probiotique (Micromonospora cremea) et son hôte Pisum sativum (pois). Il examinera la capacité de l’actinobactérie probiotique à stimuler la tolérance de la plante aux sols pollués par des métaux lourds. Les découvertes aideront à formuler de meilleures méthodes de gestion des sols et des pratiques agricoles durables.
Objectif
Agriculture is currently confronting (i) an increasing human population and (ii) limitations of soil use due to, among other reasons, pollution levels above food safety threshold values. Some agricultural practices increase the heavy metal content (HM) of agricultural soil, representing an important threat for the European agricultural development. The use of microorganisms as plant growth promoters has been increasingly studied for a number of years, but it has only recently been proposed to improve plant metal tolerance. Regrettably, plant-microorganism-pollutant interactions are still poorly understood and the molecular underlying mechanisms are mostly unknown. The abovementioned challenges for agricultural production require the study of these mechanisms to better promote a more efficient and sustainable agriculture. This project will venture into new unchartered territory by focusing on the molecular interactions between a probiotic actinobacterium (Micromonospora cremea) and its host, Pisum sativum (garden pea), in the presence of HMs. We will evaluate the capacity of M. cremea CR30 to improve plant tolerance to HM polluted soils, in addition to unraveling the molecular dialogue during the first and late steps of their interaction. Early step interactions are crucial in plant promotion and protection against external stresses, like pollution by HM. Here, we propose the use of new -omic technologies to study these molecular interactions between plants and microorganisms under metal stress, providing a new pathway for an improved soil management. This project addresses a crucial objective in food security, the development of sustainable agricultural practices to control potentially adverse HM effects on plant health.
