Understanding then rewiring nodulation:

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.

How does cell identity affect nitrogen responses and nodulation, and can we re-tune it?

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.

Exploiting cross-talk to direct crop improvement:

To create a realistic model of plant resource use it is critical to study the combined effect of many environmental factors since plants have to balance many selective pressures. For example, acquiring a feature that has a positive impact on water uptake might also have a negative impact on disease resistance. Our work in this area includes:

Engineering microbial effector systems in plants:

Application of cell type analysis to delineate genes acting 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 in the Warwick Integrative Synthetic Biology Centre).
