Other claims from this paper (9)
- Intervention effect The ssi1 mutation caused constitutive PR gene expression.
- Intervention effect ssi1 restored resistance to an avirulent Pseudomonas strain in npr1-5 plants.
- Observation ssi1 plants were small and spontaneously developed lesions.
- Observation ssi1 plants accumulated elevated SA levels.
- Intervention effect Preventing SA accumulation with nahG suppressed all ssi1 phenotypes.
- Intervention effect BTH restored lesion formation and PR gene expression in nahG-expressing plants.
- Intervention effect The nahG gene suppressed PDF1.2 expression in ssi1 npr1-5 plants.
- Intervention effect Exogenous BTH restored PDF1.2 expression.
- Mechanism The authors propose SSI1 modulates cross-talk between SA and jasmonic acid/ethylene defense pathways.
