Abstract excerpt

Ros is a chromosomally-encoded repressor containing a novel C2H2 zinc finger in Agrobacterium tumefaciens. Ros regulates the expression of six virulence genes and an oncogene on the Ti plasmid. Constitutive expression of these genes occurs in the spontaneous mutant 4011R derived from the octopine strain Ach-5, resulting in T-DNA processing in the absence of induction, and in the biosynthesis of cytokinin....
