title: Mobilization of Tn5 insertions from Rhizobium fredii by pJB3JI.
abstract: Techniques for in vivo cloning were used with the fast-growing nitrogen-fixing soybean microsymbiont R. fredii USDA 191. Selection for transfer of Tn5 insertions from R. fredii USDA 191 containing the gene-mobilizing plasmid pJB3JI provided recombinants at up to 400 times the background mutation level. These techniques may be useful for future genetic analysis of R. fredii.
