The virulence (vir) loci of the hairy-root-inducing plasmid pRiA4 are essential for pathogenicity of its host Agrobacterium rhizogenes A4. We have now determined the nucleotide sequence of virB...
Structural Characterization of the virB Operon on the Hairy-root-inducing Plasmid A4 (1998)
Liang, Yajie, Aoyama, Takashi, Oka, Atsuhiro
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...

The eukaryotic cell division cycle is tightly controlled by a class of protein kinases. Arabidopsis CDC2a has been considered to encode one of those protein kinases because it is expressed in...
The virulence regulon of the Agrobacterium hairy-root-inducing plasmid A4 is controlled by a two-component regulatory system, the VirA-VirG system. The VirA protein senses plant factors and transfers...

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...

The replication origin of the E.coli K-12 chromosome has been isolated as autonomously replicating molecules (oriC plasmid), and the DNA region essential for replicating function (oriC) has been...

The replication origin region of the Escherichia coli K-12 chromosome has been cloned, and a region of 245 base-pairs has been shown to contain all the information for autonomous replication (defined...
Nucleotide sequence of the asnA gene coding for asparagine synthetase of E.coli K-12 (1981)
Nakamura, Masataka, Yamada, Masao, Hirota, Yukinori, Sugimoto, Kazunori, Oka, Atsuhiro, Takanami, Mituru
We have subcloned the asnA gene of E. coli K-12, a gene coding for asparagine synthetase, from a previously cloned 6 mega-dalton segment of E. coli chromosome containing the DNA replication origin,...

Plant cells frequently undergo endoreduplication, a process in which chromosomal DNA is successively duplicated in the absence of mitosis. It has been proposed that endoreduplication is regulated at...

Phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] functions as a site-specific signal on membranes to promote cytoskeletal reorganization and membrane trafficking. Localization of PtdIns(4,5)P2...

Following meiosis, plant gametophytes develop through two or three rounds of mitosis. Although the ontogeny of gametophyte development has been defined in Arabidopsis thaliana, the molecular...
