Nutrient acquisition is the basis of life. With the ERC project ‘SymbioticExchange’ we aim at understanding nutrient exchange in the arbuscular mycorrhiza (AM) symbiosis of plants with nutrient-delivering fungi. This symbiosis is detected in the oldest land plant fossils and considered a prerequisite for plant life on land. It is wide-spread in the plant kingdom and its secondary loss is the exception.
AM improves plant nutrition, stress resistance and general plant performance. The hallmark of the symbiosis are the arbuscules, highly branched hyphal structures, which develop in root cortex cells. They build a large membrane interface with the plant derived peri-arbuscular membrane (PAM) that surrounds them. Most mineral nutrients are delivered to the plant at the arbuscules and taken up via the PAM into plant cells through transporter proteins.
In return, the fungi receive up to 20% of the photosynthetically-fixed carbon. The balance in mineral-nutrient-gain-for-carbon-loss influences the effect of the symbiosis on plant growth and yield. However, the full range of transported nutrients, any mechanisms regulating transport and the balance in molecular exchange are unknown.
‘SymbioticExchange’ strategically integrates transcriptomics, phosphoproteomics, metabolite profiling and protein-protein interaction analysis, with reverse genetics, cell biology and transport physiology to identify novel plant and fungal transporters involved in symbiotic nutrient and metabolite exchange, and to understand the molecular mechanisms underlying the regulation of novel and known transporters.
