Effect of arbuscular mycorrhiza establishment on the genetic structure and diversity of bacteria in the rhizosphere of Medicago truncatula
National audience; The rhizosphere is the volume of soil which is influenced by plant root activity. Plant roots release 20% of the photosynthates into the rhizosphere. This process sustains the development of an active free living microflora in the rhizosphere compared to the bulk soil. Plants establish also symbiotic associations with soil microorganisms. Arbuscular mycorrhizas (AM) are mutualistic symbioses between soil fungi and plant roots. AM contribute to plant adaptation to low fertility environments. AM are established by 80% of terrestrial plant families including major crop plants. AM are also ancient symbiosis (400 million years). AM are known to be non-specific associations. Ho…
