| Abstract: | Summary Rhizobium deoxyribonucleic acid has been detected within Vicia faba root cells by in situ hybridization and autoradiography after exposure of root apexes to Rhizobium viable cells.
Reannealed regions are localized into the cortex cells; the presence of bacterial DNA is specific for the root tissue; labelled
regions were not detectable within apexes exposed to non-nodulating strains or to bacteria other than Rhizobium; Rhizobium
DNA was not detectable in tissues of plants other than its leguminous host. re]19750313 |
