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
