Growth and metabolism in cotton and tobacco callus cultures

Abstract

Activities of key enzymes of glycolytic and pentose phosphate pathways and krebs cycle were less in tobacco callus than in cotton callus cultures grown under identical conditions. The initial period of growth was characterized by high activities of invertase, acid phosphatase, hexokinase, fructose diphosphate aldolase, malate dehydrogenase, succinate dehydrogenase, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase; the activities of these enzymes declined during the remainder period of growth.
