The Movement Protein of Some Plant Virusesal and viral infection often modifies their structure. Cell-to-cell spread (movement, transport) requires a virus-coded protein which presumably carries out the modification. By Western blot and immunoelectron microscopy, the movement proteins of alfalfa, tobacco and cauliflower mosaic viruses were

Signalling in Viroid Pathogenesiseraction with the host plant is still far from complete. Viroid pathogenesis poses many intriguing questions; these have to be answered without any viroid-specified protein to which to attribute a pathogenic r?le. Here we present a view of viroid pathogenesis in which viroid molecules are considered

The Molecular Biology of Satellite RNA from Cucumber Mosaic Virusforms induce new symptoms. The molecular basis of these effects is being investigated as a model for disease processes in plants and so that the attenuation property can be exploited in the genetic engineering of virus resistant plants. Mutation analysis has revealed two separate functional domains

Recognition and Disease Development in the Tobacco-TMV System systemically infected plants photosynthetic electron transport is reduced; photosystem II activity is affected most in the lower leaves that do not show symptoms. In the upper, mosaic-diseased leaves, the delineation of light-green and dark-green areas can be masked but not altered by plant growth

Entry of Tobacco Mosaic Virus RNA into Tobacco Chloroplasts , and ,n of virus and viral-coded components within that organelle. Our studies have been directed at ascertaining how these virus-related components gain entry into the chloroplasts. We prepared chloroplasts from either directly-inoculated or systemically-infected leaves of TMV-infected tobacco, and from

Modifications of the Coat Protein Gene of Tobacco Mosaic Virus Resulting in the Induction of Necrosie coat protein gene have been found to induce a hypersensitive reaction (HR) in plants with the . genotype. Several of these coat protein point mutations also induce a systemic necrosis on . genotype plants. Partial deletions of the coat protein gene have been found to induce a generalized necrosis

Two experimental approaches were tried: 1. “stripping mapping” by nitrous acid mutagenesis with particles partially uncoated with SDS and mapping necrotic mutants relative to the degree of stripping; 2. nitrous acid mutagenesis under “single-hit” conditions, selection of local lesion mutants on
