Biochemical changes in embryogenic and non-embryogenic calli of Zea mays L.

Abstract Embryogenic cultures derived from immature glumes of Zea mays L. were studied for the isoenzyme patterns of peroxidase, esterase and malate dehydrogenase. Two slow migrating cathodal isoperoxidase, specific esterase and malate dehydrogenases present in the embryogenic calli, were absent in non-embryogenic calli, which may indicate an association of these specific isozymes with embryogenic calli.
