Other claims from this paper (6)
- Intervention effect The non-pathogenic fungal elicitor induced PR gene expression in tobacco to a much higher level than the pathogenic elicitor.
- Intervention effect The non-pathogenic elicitor induced resistance of tobacco seedlings to Phytophthora parasitica var. nicotianae, but the pathogenic elicitor did not.
- Intervention effect Protection by the non-pathogenic elicitor lasted more than 3 weeks, whereas salicylic acid or its combination with methyl-jasmonate induced resistance for only a few days.
- Intervention effect The combination of arachidonic acid and cellulases gave more than an additive effect on activation of the osmotin gene.
- Mechanism Inhibitor studies suggest that ethylene is involved in osmotin induction by the two elicitors.
- Mechanism Ethylene, jasmonate and salicylic acid are involved in the induction of PR-1 and osmotin by the mycelial wall elicitor of a non-pathogenic fungus.
