This can be explained by the extremely unstable ROS synthesis/deactivation system in seedlings of different varieties, sensitive to pathogen action, and possible insufficient levels of antioxidant enzymes.
The wheat variety, which is sensitive to pathogen action, has showed a substantial (100%) increase in the TBARS contents, while the other varieties has shown lesser (40%) changes in the TBARS content as compared to the control.
Myronivska 808 (a Ukrainian selection)—a variety, sensitive to pathogen action; Roazon (a French selection)—a relatively resistant variety, which has the highest level of resistance in the world; and.
The changes in the TBARS content in the variants with seed treatment using Cu nanoparticles with and without infection were similar to the ones observed separately for seedlings exposure to the pathogen (like in the variant with Myronivska 808 a variety, sensitive to pathogen action).
These results suggest that secretions-differentiated macrophages may become more sensitive to pathogen-associated molecular patterns, like LPS and LTA.
Thus, HSP90 is key to maintaining the responsive plasticity of the defense system; reduction of HSP90 function predisposes the plant to herbivore defense but renders it sensitive to pathogen attack.
Currently, the widely planted grape cultivars are very sensitive to diverse pathogens.
In birds, it can result in tumours or immunosuppression, making the birds more sensitive to other pathogens.
In contrast, the hsp90.2-3 hsp90.2-3th a point mutanton in the ATP-binding domain of AtHSP90.2 is knowitho be more sensitive to biotrophic pathogens.
A significant increase of the TBARS content was noticed in seedlings of the Myronivska 808 variety, sensitive to this pathogen action, on the day following the inoculation with the pathogenic fungi.
Despite this drawback, some mouse strains have been shown to be highly sensitive to the pathogen, and have been used to study B. abortus pathogenesis and evaluate vaccine candidates for the past two decades [23], [24], [25], [26], [27], [28].
