Summary and Conclusions
An analysis of the lead-containing deposit found concentrated in the region of cell proliferation of roots of seedlings grown in culture solutions containing lead was made by micro-chemical methods. The various tests indicate that the precipitate is a combination between lead and an organic sulphydryl compound analogous to if not glutathione itself. The implications of this finding are discussed in the text.
