Sym Plasmids in RhizobiumJaponicum
Chapter
Abstract
Rhizobiumjaponicum strains PRC191 and PRC193 are fast-growing strains that were isolated in the People’s Republic of China (H. Keyser et al., 1982). Recently it was shown that these strains have nif and nod genes on large plasmids (P. Masterson et al., 1982, and unpublished).We have introduced Tn5 into the Sym plasmids of PRC191 and PRC 193. The Sym plasmids are not self-transmissible. Therefore, we introduced a helper plasmid, pRL180 (P.J.J. Hooykaas et al., 1982), into these strains to promote plasmid mobilization to other Rhizobia and Agrobacterium strains.
