The effect of modulating strigolactone signalling on leaf development in various lines
We have been heavily involved in defining the core mechanism of strigolactone signalling in flowering plants, but much remains to be understood about downstream signalling events. Furthermore, evolutionary analyses suggest that the strigolactone signalling pathway we have defined had only evolved relatively recently. We aim to dissect strigolactone signalling in a range of plant species at greater depth.

Evolution of strigolactone and KAI2-Ligand signalling
Role of SL and KL signalling in root development
Downstream signalling events in the SL and KL pathways
