trans-Acting virulence functions of the octopine Ti plasmid from Agrobacterium tumefaciens.
All Ti plasmid-encoded virulence functions that were studied act in trans. An octopine Ti plasmid-specific vir operon, called vir-O, located on an EcoRI restriction fragment has been characterized. Sequences with promoter activity in Escherichia coli were identified for a second vir operon, called vir-C, which was located close to the position of vir-O.
