Abstract: | The Ri plasmid of an agropine-type Agrobacterium rhizogenes, strain HRI, was cloned in a cosmid and mapped with the restriction endonucleases BamHI, EcoRI, KpnI, SmaI, and XbaI. This plasmid is almost identical to pRi1855 and pRiA4b. A study by Southern hybridizations of the homologies with octopine pTiB6806 and nopaline pTiC58 makes it possible to propose the localization of certain functions on this plasmid, such as virulence, agropine catabolism, agropine synthesis, and the origin of replication. |
