The ability to take up mineral nutrients, particularly nitrogen and phosphorus, is generally the major limitation to plant growth. Because of this farmers apply nitrogen and phosphorus through fertiliser application to promote crop growth. Sustained yields are dependent on this fertiliser application, but it comes at a high price, both in the cost of the fertiliser and the environmental damage that results from its use. 

A number of plant species have evolved beneficial interactions with micro-organisms that facilitate the uptake of these nutrients. Legumes form symbiotic interactions with arbuscular mycorrhizal fungi that facilitate phosphate uptake and with rhizobial bacteria that provide the plant with a source of nitrogen. The establishment of these symbioses involves a conserved symbiosis signalling pathway. This signalling pathway is present in most plant species, including cereals, as the arbuscular mycorrhizal association is widespread. 

Our work focuses on understanding the signalling mechanisms that allow the associations with these beneficial micro-organisms and the use of this information to transfer the nitrogen-fixing capability from legumes to cereal crops. Our work has implications for global agriculture, but we are most interested in the application of our work to benefit small-holder farmers in Sub-Saharan Africa.
