Lead is a heavy metal of particular concern with respect to environmental quality and health. The lack of plant species that accumulate and tolerate Pb is a limiting factor to understand the molecular mechanisms involved in Pb tolerance. In this study we identified Hirschfeldia incana, a Brassicaceae collected from metalliferous mine spoils in Moro...

Auxin controls multiple aspects of plant growth and development. However, its role in stress responses remains poorly understood. Auxin acts on the transcriptional regulation of target genes, mainly through Auxin Response Factors (ARF). This study focuses on the involvement of SlARF4 in tomato tolerance to salinity and osmotic stress. Using a rever...

Nitrogen stress increases lipids content in microalgae, the main feedstock for algal biodiesel. Sodium tungstate was used in this study to implement nitrogen stress by inhibiting nitrate reductase (NR) in Dunaliella tertiolecta. The reduction of NR activity was accompanied by reduction of chlorophyll and accumulation of lipids. One-stage and two-st...

Le projet AMIR (Activité MInière Responsable : Enjeux, défis et solutions au Maroc) a pour ambition de contribuer à co-construire un laboratoire « réseau » interdisciplinaire et transdisciplinaire de référence internationale dans le domaine de l’activité minière responsable. A ce stade, il associe 4 équipes fondatrices, à partir de programmes de “recherche, développement, formation et innovation” qui seront pensés et menés en synergie.  Les 4 équipes sont : 1-L’Equipe Biotechnologie et Physiologie Végétales, Centre de Recherche en Biotechnologies Végétale et Microbienne, Biodiversité et Environnement, (BioPV) de la Faculté des Sciences, Université Mohammed V de Rabat; 2-Le Centre d’étude et de recherche en aménagement et urbanisme de Institut National d’Architecture et d’Urbanisme de Rabat; 3-L’UMR IRD 215 PRODIG; 4-L’UMR IRD 161 CEREGE. Les principales équipes associées au Maroc sont : Le Laboratoire “de Chimie des Matériaux et de l’Environnement” de la faculté de sciences de Marrakech et l’Equipe “Valorisation des Ressources, Environnement et Développement Durable” de l’Ecole Nationale Supérieure des mines de Rabat. L’objectif est d’élargir les équipes en fonction des compétences complémentaires et des programmes en partenariat public/privés. l’objectif du LMI AMIR est d’accompagner l’activité minière dans une perspective de responsabilité croissante, de réduire les impacts négatifs, et de restaurer les environnements dégradés, d’améliorer la gouvernance, demande une implication plus forte et plus interdisciplinaire de la science : l’approche holistique du LMI AMIR contribuera à produire les connaissances nécessaires, et permettra de proposer des solutions concrètes et acceptées par la majorité des acteurs.  Le LMI permettra l'élaboration -d’analyses et de diagnostics exhaustifs et robustes scientifiquement, -de suivis dans le temps des impacts (notion d’observatoire), -de propositions concrètes de réduction des impacts et de restauration des environnements dégradés, dans une vision partagée d’économie circulaire diversifiée et plus solidaire Les équipes fondatrices ont toutes une forte expertise dans leurs domaines respectifs relevant soit des sciences de l’ingénieur, des sciences de la nature, soit des sciences humaines et sociales. Chacune a travaillé ces dernières années en multidisciplinaire et/ou interdisciplinaire au sein de son propre champs thématique (bio-géosciences de l'environnement, biotechnologies, sciences humaines et sociales), avec une expérience acquise de longue date sur des terrains miniers diversifiés en Afrique de l’ouest et centrale, en Nouvelle-Calédonie, en Amérique latine, en France et au Maroc. De plus, à partir de leur expérience commune au Maroc de plusieurs années, voire de dizaines d’années pour certains, les équipes fondatrices (et associées) proposent de se fédérer autour d’un projet résolument interdisciplinaire et transdisciplinaire à construire, partant de programmes de recherche menés ensemble sur deux territoires miniers représentatifs de l’ensemble de la problématique au Maroc, sites miniers abandonnés et site miniers actifs.

Le Maroc est connu par ses nombreux sites miniers dont plusieurs sites d’extraction de métaux. Leur exploitation durant plusieurs décennies a entraîné l’accumulation de milliers de tonnes de résidus pour la plupart abandonnés à l'air libre. Ces résidus, riches en métaux lourds potentiellement fortement toxiques, sont à l'origine de problèmes environnementaux et de santé publique. De plus, en raison d’un couvert végétal épars et peu abondant et d’une érosion très active dans ces régions semi-arides à arides, les métaux sont dispersés ainsi à plusieurs kilomètres des sites d’origine, par le vent et par le ruissellement des eaux de surface vers les régions habitées avoisinantes. La contamination est alors aggravée, plus dévastateur et difficile à contrôler. Dans une démarche de réduction/mitigation de la contamination et de protection de ces environnements, la mise en place d'une approche de phytoréhabilitation (phytoremédiation) de ces sites pollués demeure nécessaire afin de limiter les risques engendrés pour la biodiversité et la santé de l'homme. Cependant, à l’heure actuelle, le principal obstacle au développement de la phytoremédiation réside dans le faible nombre d’espèces potentiellement utilisables à l’échelle industrielle, la faible biomasse des plantes utilisées, ainsi que le manque en connaissances des mécanismes physiologiques et du déterminisme génétique de la tolérance et de l’hyperaccumulation des métaux. C’est dans ce contexte que s’inscrit notre projet, qui a pour objectifs : - Caractériser les environnements et les substrats dans plusieurs zones minières au Maroc (Kettara (Marrakech) et Aouli-Zaida-Mibleden). - Explorer et caractériser la flore des zones contaminées par les métaux. - Etudier la réponse des plantes aux stress métalliques de point de vue morphologique et physiologique. - Identifier les bases moléculaires de la tolérance et l’accumulation des métaux lourds chez les plantes. - Développer des stratégies de réhabilitation (essai pilote) de ces sites par phytoremédiation. - Encourager le transfert de procédés et d’expertise et valoriser l’expertise. https://en.ird.fr/node/8189
