Genes required for the full expression of Shigella virulence are on both the chromosome and a large virulence-associated plasmid. Expression of one or more virulence (vir) genes is temperature-regulated, wild-type strains being virulent (invasive) when grown at 37 degrees C but phenotypically avirulent (noninvasive) at 30 degrees C. A vir::lac operon fusion located on the virulence plasmid, whi...

Neurons in the trigeminal sensory nuclei (TSN) were indicated to project simultaneously to the cerebellar paramedian lobule (PML) of both sides by way of axon collaterals in the rabbit. Injections of Fast Blue and Diamidino Yellow made in twelve rabbits into the regions of the left and right PML cortex, respectively, resulted in retrograde double labeling of neurons in the principal trigeminal ...

The VirA/VirG two-component regulatory system of Agrobacterium tumefaciens regulates expression of the virulence (vir) genes that control the infection process leading to crown gall tumor disease on susceptible plants. VirA, a membrane-bound homodimer, initiates vir gene induction by communicating the presence of molecular signals found at the site of a plant wound through phosphorylation of Vi...

The vir genes of Agrobacterium tumefaciens tumor-inducing (Ti) plasmids direct the transfer of oncogenic portion of the Ti (tumor-inducing) plasmid that is transferred to plant cells (T-DNA) into plant cells and are coordinately induced by plant-released phenolic chemical signals. We have used DNA microarrays, representing all genes of the octopine- and nopaline-type Ti plasmids, to identify al...

An extremely low mass companion to the solar-type star 70 Virginis is inferred from the observed periodic Doppler reflex motion of the primary during 8 yr. The minimummass (M2 sin i) of 70 Vir “B” is 6.6 Jovian masses (MJ), which falls in the mass range associated with “extrasolar giant planets” (0.3–15 MJ ). An orbital fit to the velocities yields a period P 5 116.6 days, an amplitude K 5 318 ...
