The aims of the proposal are to investigate the sequence of                events involved in the early stages of nodule development using                 specific Rhizobium mutants that induce the formation of nodules                 on alfalfa roots which are arrested at distinct stages of their                 development.  The PI hypothesizes that infection thread formation                                                                                               is the second signal for nodulin gene expression, and that the                  nod and exo genes interact in the early stages of nodule                        formation.  Dr. Hirsch is proposing a multi-faceted approach                    utilizing techniques of plant tissue culture, genetics, molecular                                                                                               biology and electron microscopy.                                                Both bacterial genes and plant genes are involved in the                        formation of a nitrogen fixing root nodule.  Understanding the                  roles of these different genes in nodulation is essential if we                 are to transfer the nitrogen fixing capability into nonleguminous                                                                                               plants.
