Stable Isotope Probing Of The Rhizosphere

Comments Off on Stable Isotope Probing Of The Rhizosphere Projects

Plants release a large amount of the carbon that they capture through photosynthesis into soil from their roots. This exudation of carbon from roots into the soil leads to enrichment of specific bacteria, which is of interest as this has been shown has been shown to impact plant growth and health. Furthermore, growing plants represent a major terrestrial source of methanol, an organic compound with a significant role in ozone formation. However, there is a large difference between the estimated and measured concentrations of methanol entering the atmosphere, and this disparity is potentially attributable to terrestrial and plant-enriched methylotrophs, and this is the main focus of this research project. The study site is the Antirrhinum wall at the John Innes Centre owned Church Farm in Bawburgh, maintained as undisturbed former grassland.
