Nodulation: legumes can work with symbiotic bacteria to gain nitrogen, why can't all plants?

Unlike most plants, legumes (such as peas and beans) are able to fix atmospheric nitrogen (nodulation), so break the agricultural dependency on expensive and environmentally costly nitrogen fertilisers. If we understand the molecular basis of why legumes nodulate but other plants don't we could improve nitrogen-use efficiency in our crops. This would improve food security, a major research priority and one within the agri-tech strategy remit.

What contribution does each cell type of the root make to the whole root response to nitrogen?

We use Fluorescence-Activated Cell Sorting (FACS) combined with genomics to measure the gene expression of all regulatory pathways and interpret them in the context of root phenotypes. This is critical since nodules develop from a specific root cell type and root environmental responses have a high degree of cell specificity. We also want to investigate how rhizobial responses (nodulation) intersect with responses to other mutualists in the rhizosphere to improve plant productivity.

Molecules that work in specific cell types can help to trigger specialised responses - synthetic biology.

Application of cell type analysis can help distinguish genes that act in specific locations and under specific conditions. We can use this to predict which promoters and genes could be engineered to enable new functions, including altered plant disease responses and altered mutualistic responses (Theme 4 SynEffectors in the Warwick Integrative Synthetic Biology Centre).
