Abstract

Triphenyltin compounds have been found to inhibit the growth ofCeratocystisulmi, the fungal agent of Dutch elm disease. To determine where the tin compounds interacted with the fungus cell, tin Mössbauer spectra of the treated cells, cell walls, and cellular organelles were measured at 80K. The compounds examined included triphenyltin bromide, chloride, hydroxide, and iodide. The spectra of the whole cells were different from the spectra of the solid tin compounds and exhibited two major lines whose parameters were the same for all cells. This suggests that the tin compounds were bound to the cell as the triphenyltin cation. The same spectrum appears with cell-wall fraction, and a weak signal is present in the spectrum of treated cellular fractions. These results suggest that the tin compounds are bound to the cell walls.
