A major thrust of our research is to understand how legume nodules evolved. To do this, we use a multidisciplinary approach, from fine structure studies to molecular methods. The latter involves the expertise of the SCRI Cell and Molecular Genetics group led by Wayne Powell. We are developing markers for nodule characters and quantitative traits associated with nitrogen fixation. Our laboratory houses the world's largest collection of preserved legume nodules (many collected by H.D.L. Corby) and we have major international collaborative programmes, especially with groups in Africa and South America.
