Other claims from this paper (9)
- Intervention effect TMV inoculation increased endogenous SA in inoculated and virus-free tobacco leaves.
- Observation SA levels were highest in and around TMV-induced necrotic lesions.
- Observation TMV-inoculated tobacco leaves contained a SA conjugate tentatively identified as O-beta-D-glucosyl-SA.
- Observation The SA conjugate occurred only in necrotic leaves, not phloem exudates or uninoculated leaves.
- Intervention effect Reduction in free SA after feeding did not prevent subsequent PR-1 protein accumulation.
- Mechanism Lack of SA accumulation at 32 degrees C was not attributable to SA glucosylation.
- Intervention effect Adding SA to hydroponic medium elevated leaf SA in virus-free tobacco.
- Intervention effect Increasing endogenous SA to systemic-acquired-resistance levels reduced TMV lesion area.
- Mechanism SA was interpreted as a likely natural inducer of PR proteins and systemic acquired resistance.
