The key to making root nodules - new tricks for old hormones. This project aims to use and develop new chemical and microscopy-based tools to test whether the cell-type specific plant hormone changes induced by rhizobia in legumes can be triggered in non-legumes. Most crop plants rely on fossil fuel-derived nitrogen fertilisers, while legumes benefit from biologically-fixed nitrogen through a symbiosis with rhizobia bacteria that initiate nodules. It is not understood why non-legumes cannot form ....The key to making root nodules - new tricks for old hormones. This project aims to use and develop new chemical and microscopy-based tools to test whether the cell-type specific plant hormone changes induced by rhizobia in legumes can be triggered in non-legumes. Most crop plants rely on fossil fuel-derived nitrogen fertilisers, while legumes benefit from biologically-fixed nitrogen through a symbiosis with rhizobia bacteria that initiate nodules. It is not understood why non-legumes cannot form this symbiosis. This project aims to apply detailed knowledge of nodulation in model legumes to a phylogenetically diverse range of nodulating and non-nodulating plant species. This is expected to give new insight into the evolution of nodulation and advance the long held goal of extending nodulation to non-legumes.Read moreRead less
