• Enzymes involved in malate metabolism, viz., glutamic-oxalacetic transaminase, malate dehydrogenase, malic enzyme and phosphoenolpyruvate carboxylase, had severalfold higher specific activities in organ-forming callus cultures of tobacco compared to non-organ-forming cultures. These activities increased considerably during the days preceding shoot and root differentiation. While malate accumulated until day 15 in non-organ-forming callus, it accumulated up to day 6 in shoot-and root-forming callus. Total and reducing sugars accumulated until day 3 and declined thereafter in all the cultures. Thus, tobacco callus may utilize this pathway for deriving reducing power which is required for organogenetic processes.
