    AnnotationChanges in the proteins, chlorophyll, virus content and activity of key enzymes of viral RNA biosynthesis wereinvestigated in the light- and dark-green regions of tobacco leaves systemically infected with tobacco mosaic virus. The comparative analysis of soluble proteins from healthy and light- or darkgreen regions of leaves revealed that the main soluble proteins are equal in pattern but differ inquantity. The contents of chlorophylls did not differ from healthy tissues in the dark-green islands but were considerably lower in the light-green regions. The content of virus in light-green tissues was about 10 times higher than in the darkgreen islands. The activities of key enzymes of oxidative pentosephosphate cycle did not differ from healthy tissues in the dark-green islands but were considerably higher in the light-green tissues when compared with healthy control. Similar relationships were observed for ribonuclease, phosphomonoesterase and phosphodiesterase activities.
