Mutation of the miaA gene of Agrobacterium tumefaciens results in reduced vir gene expression.

Abstract excerpt

vir regulon expression in Agrobacterium tumefaciens involves both chromosome- and Ti-plasmid-encoded gene products. We have isolated and characterized a new chromosomal gene that when mutated results in a 2- to 10-fold reduction in the induced expression of vir genes by acetosyringone. This reduc...
