Cytochemical Evidence for the Occurrence in Plants of a Novel Microbody that Contains Peroxidase
The Institute of Low Temperature Science, Hokkaido University Sapporo, Japan
A cytochemical study with 3,3'-diaminobenzidine revealed the presence of peroxidase in the microbodies which were recently found in the xylem parenchyma cells of wintering poplar (Sagisaka and Asada 1981). The peroxidative reaction was not inhibited by 3-amino-l,2,4-triazole, but was completely inhibited by KCN. There was no detectable staining in the absence of added H2O2.
