Soil metagenomics

Soil microbiome

 The soil microbiome is the complete set of microbes that can live in soil ecosystems.

  • Soil represents the greatest microbial reservoir of biological diversity
    • more than 30,000 prokaryotic species
    • presence of soil microbes depends on many environmental factors including geographic location, salinity, temperature, oxygen, nutrients

  • Plant-microbe interactions 
    • microbes are essential for plant growth and health
    • soil serves as a major source of plant-associated bacteria

Rhizosphere microbiome


Rhizosphere microbiome consists of all soil microbes that colonize the roots of plants.

  • Microbes support plant growth and health
    • microbial colonization of roots is beneficial to plant growth and health
    • microbes help to absorb nutrient absorption and to protect against pathogens

  • Plant-specific microbioms
    • plants are able to control their rhizosphere microbiom by root secretions
    • different plant species growing on the same soil attract different microbes
