Structural characterization of the virB operon on the hairy-root-inducing plasmid A4.
The hairy-root-inducing plasmid A4 (pRiA4) is capable of conferring tumorigenic symptoms on plants upon infection by its host bacterium, Agrobacterium rhizogenes. The virB operon on pRiA4 has been sequenced and found to be composed of 11 genes, virB1 to virB11, whose products mostly appear to be associated with the cell membrane. A novel structural characteristic is frequent overlappings betwee...
متن کاملSequence determination and characterization of the replicator region in the tumor-inducing plasmid pTiB6S3.
The replicator region of the 195-kilobase-pair (kb) tumor-inducing plasmid pTiB6S3 was previously identified by isolation of a 6.8-kb miniplasmid (B.P. Koekman, P.J.J. Hooykaas, and R.A. Schilperoort, Plasmid 7:119-132, 1982). This miniplasmid was joined to ColE1-based vectors and subjected to mutagenesis. The resulting mutant plasmids were examined for their ability to replicate autonomously i...
متن کاملCucumopine Type Agrobacterium Rhizogenes K599 (ncppb2659) T-dna Mediated Plant Transformation and Its Application
Agrobacterium rhizogenes infects plants to induce hairy roots. It is classified into four different types such as agropine, mannopine, cucumopine and mikimopine. A.rhizogenes K599, also known as NCPPB2659, is a representative strain of the cucumopine type. In this review, we discussed the functions of 11 genes on the T-DNA of Ri plasmid pRi2659 in K599. We summarized the infectivity of K599 on ...
متن کاملSignal structure for transcriptional activation in the upstream regions of virulence genes on the hairy-root-inducing plasmid A4.
The inducibility of the vir genes (virA, -B, -C, -D, -E, and -G) on pRiA4 was examined at the transcriptional level, and the RNA-starting sites were determined by S1-nuclease mapping and primer-extension experiments. All of these genes were inducible, while virA, -E, and -G were transcribed even under noninducing conditions. Each transcription of virB, -C, -D, and -E was initiated at one partic...
