Other claims from this paper (11)
- Observation VAM cells supported less PVY(NN) accumulation than NC745 cells.
- Observation NC745 accumulated PVY progeny at the same level as susceptible Burley 21.
- Observation PVY(NN) cell-to-cell movement was similarly impaired in VAM and NC745 tobacco.
- Observation PVY(NN) was recovered earlier from NC745 than VAM inoculated leaves.
- Observation Resistance-breaking PVY variants were recovered after PVY(NN) detection.
- Observation In VAM, emerging resistance-breaking variants remained in inoculated leaves until reinoculation.
- Association Failure of emerging variants to leave VAM leaves was associated with low accumulation and obstruction by avirulent coinfecting genotypes.
- Observation The VAM accumulation restriction factor was inherited independently of va and showed allele-dose action.
- Observation Isolated resistance-breaking variants readily overcame rvam2.
- Observation The viral modification linked to overcoming rvam2 caused a fitness loss in B21.
- Mechanism The authors infer that systemic emergence of resistance-breaking variants requires high local viral accumulation plus constrained traffic.
