Other claims from this paper (12)
- Observation The second leaf had slightly lower salicylic acid levels than younger leaves.
- Intervention effect Inoculation with Pseudomonas syringae D20 did not increase rice salicylic acid.
- Intervention effect Inoculation with Magnaporthe grisea did not increase rice salicylic acid.
- Intervention effect Inoculation with Rhizoctonia solani did not increase rice salicylic acid.
- Association Leaf salicylic acid levels correlated with generalized blast resistance across 28 rice varieties.
- Observation Rice shoots converted cinnamic acid to salicylic acid, p-coumaric acid and ferulic acid.
- Observation Rice readily converted benzoic acid to salicylic acid.
- Mechanism The results suggest rice synthesizes salicylic acid from cinnamic acid through benzoic acid.
- Observation Rice shoot salicylic acid was largely present as free acid.
- Observation Exogenously supplied salicylic acid was converted to P-0-D-glucosylSA by SA-GTase.
- Observation SA-GTase activity rose sevenfold after six hours of 1 mm SA feeding.
- Observation Rice roots and shoots showed similar SA-GTase induction patterns with maximal induction after 1 mm SA feeding.
