Analysis of the acid-soluble nucleotides of fully expanded primary bean leaves and similar leaves previously inoculated with southern bean mosaic virus indicated the presence of 21 organic phosphorus compounds, 11 of which were present in sufficient concentration for identification and quantitative analysis. The adenosine triphosphate concentration of infected and normal leaves varied in a similar and apparently cyclic manner with lowest quantities during the light and highest quantities during the dark periods. A higher concentration was found in diseased tissue at all times of sampling.
