Other claims from this paper (12)
- Intervention effect Tobacco rattle virus made RRV antigen aggregates easier to detect in protoplasts.
- Observation Both RRV strain antigens were produced in more than half of tobacco protoplasts after simultaneous inoculation.
- Association The proportion of protoplasts producing both strain aggregates depended on inoculum particle ratio.
- Observation RRV-S had greater specific infectivity and tended to dominate RRV-E.
- Intervention effect Adding RRV-S reduced the proportion of protoplasts producing RRV-E aggregates.
- Intervention effect The second RRV strain formed aggregates in fewer protoplasts after prior RRV inoculation than after TRV alone.
- Association Exclusion of the second strain increased as the interval between inoculations increased.
- Intervention effect Increasing virus concentration did not overcome second-strain exclusion.
- Observation Exclusion was weaker in RRV-E inoculated protoplasts than in RRV-S inoculated protoplasts.
- Observation Exclusion in RRV-S inoculated protoplasts was total by 12 h.
- Observation Some RRV-S infected recovered-leaf protoplasts produced RRV-E antigen after challenge.
- Observation Only 11% of challenge-inoculated protoplasts produced RRV-E aggregates despite 99% TRV infection.
