SUMMARY: Histochemical methods showed that tuber tissue and tissue culture cells of contained phase-dense particles which absorbed neutral red and fluorescent dye, and particles which contained acid phosphatase and a non-specific esterase. It is suggested that these structures may be comparable to the lysosomes of animal tissues and the lysosome-like structures of plant cells which possess similar and additional properties. During infection of tissues by there was swelling and disruption of these host cell particles, accompanied by the release of acid phosphatase and esterase. Biochemical assay for acid phosphatase confirmed that infection of host cells resulted in the liberation of acid phosphatase from a particulate to the supernatant fluid fraction of cell homogenates.
