The ability of two compounds, a cytokinin and an auxin, to stimulate tobacco cell growth and differentiation has been known for greater than 30 years, but the molecular mechanism of this activation is still unknown. Previous reports of factors endogenous in crown gall tumors of Vinca rosea that
Liposome-mediated infection of plant protoplasts with tobacco mosaic virus RNA.

Tobacco mosaic virus (TMV) RNA was encapsulated in large unilamellar vesicles (LUV) of phosphatidylserine and was introduced into protoplasts from Vinca rosea suspension cultures. Infection could be effected by brief incubation of protoplasts with the LUV containing TMV-RNA in the presence of either

Dehydrodiconiferyl alcohol glucosides (DCGs) are derivatives of the phenylpropanoid pathway that have been isolated from Catharansus roseus L. (Vinca rosea) crown gall tumors. Fractions containing purified DCGs have been shown previously to promote the growth of cytokinin-requiring tissues of
Biosynthesis of dehydrodiconiferyl alcohol glucosides: implications for the control of tobacco cell growth.

The dehydrodiconiferyl alcohol glucosides A and B are factors isolated from transformed Vinca rosea tumor cells that can replace the cytokinin requirement for growth of tobacco (Nicotiana tabacum) pith and callus cells in culture. These factors, present in tobacco pith cells, have their
Cell division promoting activity of naturally occurring dehydrodiconiferyl glucosides: do cell wall components control cell division?

Naturally occurring isomers of the dehydrodiconiferyl glucosides have been isolated from Vinca rosea crown gall tumors and have been tested for cell division promoting activities in the tobacco pith and leaf assay systems. The enantiomeric isomers A and B are active, although they are required at
Studies on the distribution and properties of a new class of cell division--promoting substances from higher plant species.

One member of a new class of cell division-promoting substances, which are nicotinamide derivatives, has been found to be present in dividing cells of tobacco and cactus. These plants are taxonomically far removed from one another and from Vinca rosea L., the plant species from which the new

Several strains of Pseudomonas aeruginosa were investigated for pathogenicity to plant tissue. Inoculations into the intercellular spaces of leaves of Vicia faba (28 degrees C) and Vinca rosea (36 degrees C) showed negative results. In leaves of Nicotiana tabacum (32 degrees C) the bacteria
