e1“Systemic resistance was induced in the leaves of Datura stramonium L., Nicotiana glutinosa, Phaseolus vulgaris var. Prince, and Chenopodium amaranticolor by localized infection with tobacco mosaic or necrosis viruses (TMV, TNV)”
e7“When treated with pancreatic ribonuclease and mixed with TNV, inhibition no longer occurred”

Other claims from this paper (6)
- Intervention effect Extracts from resistant leaves were more inhibitory to TNV infection on Phaseolus than extracts from non-resistant leaves.
- Intervention effect The 3-S RNA from resistant leaves reduced lesion number more than 3-S RNA from control leaves.
- Intervention effect The 27-S and 17-S RNA fractions from both resistant and control leaves inhibited TNV infection by similar amounts.
- Observation Inhibitory activity from resistant leaves was retained in the RNA preparation after fractionation.
- Observation The lowest molecular weight RNA from systemic-induced resistant leaves gave positive orcinol tests and a nucleic-acid absorption spectrum.
- Intervention effect Localized infection with TMV or TNV induced systemic resistance in the leaves of four test plants.
