Beneficial relationship
Zigmunds Orlovskis, John Innes Centre

Plants form beneficial (symbiotic) interactions with mycorrhizal fungi where the fungus receives sugars from plant photosynthesis for energy and in return the plant benefits from increased water and nutrient uptake as well as giving protection from pathogens. The fungal hyphae in this image, stained in blue, extend far and in between root cells, forming round arbuscules with large surface-to-volume ratios for efficient nutrient exchange. Scientists at the John Innes Centre on the Norwich Research Park are working to understand the molecular mechanisms for this plant-fungal interaction as it is fundamental for engineering enhanced nutrient uptake in crop plants where such symbiosis does not exist yet.
