Identification of pTiC58 plasmid-encoded proteins for virulence in Agrobacterium tumefaciens.

Analyses were made of the host-dependent-variation (hdv) locus of the virulence ( vir) region of the pTiC58 plasmid of Agrobacterium tumefaciens. The hdv locus is comprised of at least four genes that encode polypeptides of 13, 15, 29, and 28 kDa. Insertion of transposon Tn5 in the first gene abolishes the expression of all four genes in vitro and in vivo. Nucleotide sequence analysis of the hdv locus revealed four open reading frames tandemly arranged with spacer sequences having no promoter-like sequences and lacking the ability to bind A. tumefaciens RNA polymerase. These studies suggest that the hdv locus is comprised of at least four genes arranged in an operon in the vir region. The protein products of these genes are likely to function in some aspect of the host-range determination of A. tumefaciens.[1]
