Other claims from this paper (15)
- Intervention effect Tomato resistance-breaking TSWV strains triggered a hypersensitive response in resistant pepper.
- Intervention effect Tomato resistance-breaking TSWV strains did not trigger a hypersensitive response in resistant tomato.
- Observation The pepper isolate Pep-BL uniquely overcame both Sw-5b and Tsw resistance.
- Observation Pep-BL caused earlier and more severe symptoms in resistant pepper (12 DPI) than in resistant tomato (22 DPI).
- Observation Pep-BL accumulated to higher titers in resistant tomato than other resistance-breaking strains.
- Observation The L segment of the new TSWV strains showed 93-98% nucleotide identity with reported isolates.
- Observation The M segment of the new TSWV strains showed 90-98.5% nucleotide identity with reported isolates.
- Observation The S segment of the new TSWV strains showed 90-98% nucleotide identity with reported isolates.
- Observation Phylogenetic analyses showed that the TSWV strains clustered by geography.
- Observation Tom-CA grouped distinctly with a Mexican resistance-breaking isolate.
- Observation Pep-BL clustered with Pep-Non-RB.
- Observation No reassortment was detected among the TSWV strains.
- Observation Recombination was observed in Tom-CA, Tom-BL1 and Pep-BL.
- Observation Population genetics revealed low nucleotide diversity and evidence of purifying selection in the TSWV strains.
- Observation Codon-level analyses identified novel NSm substitutions C118F and K125R that may contribute to resistance-breaking phenotypes.
