Other claims from this paper (12)
- Intervention effect Lesions on PAL-suppressed tobacco develop at the same rate as on control tobacco after TMV infection.
- Observation Lesions induced by TMV on PAL-suppressed plants differ markedly in appearance from those on control plants.
- Observation PAL-suppressed tobacco lesions show a reduced deposition of phenolics.
- Observation Free salicylic acid levels in primary inoculated leaves of PAL-suppressed tobacco are approximately fourfold lower than in control plants after 84 h.
- Observation PR proteins are not induced in systemic leaves of PAL-suppressed tobacco.
- Intervention effect Secondary TMV infection does not restrict lesion size and number in PAL-suppressed tobacco, unlike control plants undergoing SAR.
- Observation The SAR response can be transmitted from a PAL-suppressed rootstock.
- Observation SAR is not observed when the scion is PAL-suppressed.
- Observation Treatment of PAL-suppressed tobacco with dichloro-isonicotinic acid induces PR protein expression and SAR against TMV.
- Observation Treatment with SA only partially restores SAR in PAL-suppressed tobacco.
- Mechanism De novo synthesis of SA and/or other phenylpropanoids is required for expression of resistance in systemic leaves.
- Mechanism The amount of pre-existing phenylpropanoid compounds in systemic leaves may be important for the establishment of SAR.
