Other claims from this paper (13)
- Observation R1 mutant BCTV was not infectious in Arabidopsis.
- Observation R1 mutant BCTV failed systemic movement.
- Intervention effect R2 mutant caused milder symptoms than wild type BCTV.
- Intervention effect R3 mutant caused milder symptoms than wild type BCTV.
- Intervention effect L2/L3 mutant caused milder symptoms than wild type BCTV.
- Intervention effect R3 mutant infectivity was reduced 40% to 60% relative to wild type BCTV.
- Intervention effect L2/L3 mutant infectivity was reduced 40% to 60% relative to wild type BCTV.
- Observation Only dsDNA accumulated in R2-infected organs.
- Intervention effect L4 disruption reduced infections.
- Intervention effect L4 disruption allowed viral DNA accumulation from roots to shoot tips comparable with wild type BCTV on Sei-O.
- Observation Four mutants did not produce callus-like tissue on infected organs.
- Intervention effect cycl mRNA accumulated in wild type BCTV symptomatic organs but not with the L4 mutant.
- Mechanism The authors conclude BCTV L4 ORF is essential for callus-like symptom formation.
