Abstract
Double-crystal high-resolution X-ray fluorescence spectroscopy was applied to the chemical state analysis of sulfur and phosphorus in biological samples of leaves and bones. Both S2− and S6+ states are present in all leaves. In plants infected with the mosaic virus, the abundance of S2− state was found to be less than normal.
Furthermore, the total sulfur content of leaves with the mosaic virus was less than that in normal leaves. From these results we have concluded that the mosaic virus is related to the decrease in cysteine sulfur (S2−), which is an essential component in amino acids. Most of the phosphorus in leaves and bones was found to be in P5+ state. A small amount of P3+ state, however, was also detected.
