✦ Synopsis

Peroxidases from tobacco tissue cultures have been separated by thin-layer isoelectric focusing into 12-14 isoenzymes, which have been divided into three groups according to differences in isoelectric points. The isoelectric patterns of callus tissues with and without buds have been compared with those of leaves and stems developed in vitro. Qualitatively, there was a basic similarity of the isoelectric patterns, the same isoenzymes being present in all samples. Distinct quantitative differences in the content and substrate specificity were noted for some of the isoenzymes.
