Title
Relationship between Beet Ringspot, Potato Bouquet and Tomato Black Ring Viruses
B. D. Harrison Journal of General Microbiology 1958. doi:10.1099/00221287-18-2-450
Other claims from this paper (8)
- Observation Potato bouquet and beet ringspot viruses were identified as strains of tomato black ring virus.
- Observation Tomato black ring and potato bouquet viruses were more closely related to one another than either was to beet ringspot virus.
- Observation The three viruses produced similar symptoms and had similar host ranges.
- Observation No relationship to tobacco ring spot or peach yellow bud mosaic viruses was found.
- Intervention effect When protection was incomplete, second-virus symptoms were milder than infection by that virus alone.
- Observation Tomato black ring virus strains differed in their ability to cause symptoms in plants already infected with other strains.
- Observation Plant protection and serological tests agreed broadly but incompletely.
- Association The degree of difference between tomato black ring virus strains appeared to reflect geographical separation.
