Tobacco polyamines as affected by stresses induced by different pathogens
- 1 Bulgarian Academy of Sciences, D. Kostov Institute of Genetics, Sofia, Bulgaria
A decrease of the polyamine content of tobacco leaves inoculated with fungal, bacterial and viral pathogens differing in symptom severity (mosaic, chlorosis, necrosis) was observed. The extent of the decrease was not related to the type of pathogens but to the severity of damage symptoms; hence, the polyamine decline may be regarded as a common response of tobacco to damage produced by pathogens.
