abstract：:The Agrobacterium tumefaciens Ti plasmid contains at least six transcriptional units (designated vir loci) which are essential for efficient crown gall tumorigenesis. Mutations in one of these loci, virE, result in a sharply attenuated virulence phenotype. In the present communication, we have analyzed the virE operon...
