Adenosine Triphosphate Concentration in Relation to Respiration and Resistance to Infection in Tissues Infected by Virus
Year: 1969
Type: article
Abstract: Summary When leaves of Nicotiana tabacum L. var. Xanthi were infected with tobacco etch virus, local lesion formation was accompanied by an increased rate of respiration which coincided with an increase in their adenosine triphosphate concentration. Stimulation of respiration by 2.4 dinitrophenol decreased to a low value with increasing lesion density. A combination of increased adenosine triphosphate concentration and greater adenosine triphosphate turnover may contribute towards the increased respiration of the local lesion host. Adenine greatly increased the adenosine triphosphate concentration of healthy leaves but not the respiration rate. With the local lesion leaf, where adenosine triphosphate concentration was increased by virus infection, adenosine triphosphate concentration was unaffected by adenine. Treatment of leaves with adenine increases resistance to virus infection, while healthy tissue surrounding virus‐induced local lesions is also resistant to reinfection; both give increased adenosine triphosphate concentration suggesting that this is an important factor in resistance to virus infection. Increased adenosine triphosphate concentration in the leaf may result in the production of additional host ribonucleic acid which then occupies receptor sites usually available to virus ribonucleic acid.
