Isoenzymes in cell cultures of bush bean (Phaseolus vulgaris cv. Contender): isoenzymatic changes during the callus culture cycle and differences between stock cultures
Keyword(s):
Electrophoretic analyses of isoenzyme patterns were performed with extracts of root, hypocotyl, and cotyledon callus cultures derived from a single seedling. The enzymes studied included peroxidase, polyphenol oxidase, catalase, malate and glutamate dehydrogenases, esterase, and leucine amino peptidase. Enzyme patterns changed during the culture cycle and several isoenzymes appeared only at certain times. The isoenzymatic patterns of the three cultures were very similar but persistent differences between them were observed.
