Microbiome du sol et des plantes

Recherche et / ou projets en cours

Dre Leewis est une nouvelle scientifique d’AAC et elle élabore un programme de recherche orienté vers la phyllosphère, la rhizosphère et le dépositaire de diversité microbienne qu’est le sol, particulièrement dans les systèmes de grandes cultures intégrant l’utilisation d’espèces fourragères pérennes.

Énoncés de recherches/projets

  • Étudier les interrelations entre le microbiome du sol, les cultures et leurs effets potentiels sur la productivité.
  • Caractériser ces microbiomes, explorer leur fonction et développer des applications biotechnologiques à partir de ces connaissances fondamentales.
  • Réduire, par la gestion du microbiome des plantes agricoles, l’impact négatif de la production agricole sur la qualité de l’air et de l’eau tout en intensifiant cette production par l’amélioration de la santé de l’agroécosystème selon une approche de santé globale (one health), et ainsi suffire de façon durable à la demande grandissante des marchés mondiaux.
