| Abstract: | Leaves of N. glutinosa were inoculated with tobacco mosaic virus,and infection allowed to develop in situ or in discs cut fromthe leaves and floated on water or culture solution. Extracts,made from the leaves and discs when their respiration was greaterthan that of comparable uninfected tissue, contained amountsof protein N, chlorophyll, glycollic oxidase, and mitochondrialprotein N, similar to those in extracts from uninfected tissue,but slightly less cytochrome oxidase and considerably more polyphenoloxidase.No evidence was obtained for the view that the virus-inducedrespiration reflects an increase in the amount of mitochondrialmaterial. |
