Dual control of Agrobacterium tumefaciens Ti plasmid virulence genes.
J Bacteriol 1987; 169(11):5113-8JB

Abstract

The virulence genes of nopaline (pTiC58) and octopine (pTiA6NC) Ti plasmids are similarly affected by the Agrobacterium tumefaciens ros mutation. Of six vir region complementation groups (virA, virB, virG, virC, virD, and virE) examined by using fusions to reporter genes, the promoters of only two (virC and virD) responded to the ros mutation. For each promoter that was affected by ros, the level of expression of its associated genes was substantially elevated in the mutant. This increase was not influenced by Ti plasmid-encoded factors, and the mutation did not interfere with the induction of pTiC58 vir genes by phenolic compounds via the VirA/VirG regulatory control mechanism. The effects of the ros mutation and acetosyringone were cumulative for all vir promoters examined. The pleiotropic characteristics of the ros mutant include the complete absence of the major acidic capsular polysaccharide.
