Bauer, W D

The overall goal of our current studies is to identify cellular and molecular factors that are of central importance to the colonization and infection of host roots by inoculated rhizobia in competition with indigenous soil microbes. This report covers research compelted between May 1986 and May 1987. Progress was made during the past year in areas of the role of motility and chemotaxis in nodule initiation by rhizobia, the further characterization of bacterial adhesion to host root surfaces, the effects of root exudate on bacterial attachment, the effects of bacteria and bacterial culture filtrates on bacterial attachment, the movement of rhizobia on the surface of the growing host root, and the effects of adding various nod mutants of Rhizobium meliloti on nodule formation by co-inoculated wildtype cells. 1 fig., 5 tabs.
