Constitutive mutations of Agrobacterium tumefaciens transcriptional activator virG.

Journal of bacteriology - 1 Jun 1992

Pazour G J, Ta C N, Das A

Abstract excerpt

The virulence (vir) genes of Agrobacterium tumefaciens Ti plasmids are positively regulated by virG in conjunction with virA and plant-derived inducing molecules. A procedure that utilizes both genetic selection and a genetic screen was developed to isolate mutations in virG that led to elevated levels of vir gene expression in the absence of virA and plant phenolic inducers. Mutants were isolated at a frequency...
