Bacterial Metabolism in the Rhizosphere

Recommended reading:   Climate Change and Microbial Ecology | Polymerase Chain Reaction | SUMOylation and Ubiquitination
The rhizosphere represents one of the most microbially diverse and dense habitats on the planet. The community structure of the rhizosphere varies widely, and largely is dependent on plant genotype and soil type, as well as being influenced by external climatic and anthropomorphic inputs. Microbiome analysis has highlighted wholescale differences in the rhizosphere microbiota from different ecosystems: for example contrast the communities derived from the pristine Amazonian rainforests with those from arid deserts or intensively cultivated agricultural regions. How do metabolic processes underpin the interactions of the bacterial population of the rhizosphere with their plant hosts, and examine the basis to the flux of metabolites in the rhizosphere system? Although there is not a clear delineation between the bulk soil and rhizosphere communities, metabolic functions occur in the rhizosphere for bacteria that interact directly with plant hosts, or with other rhizospheric bacteria.
