Abstract: | Sucrose synthetase and sucrose phosphate synthetase could not be detected in 7-day-old excised tomato roots grown in sucrose. These roots, however, possessed a highly active acid invertase and a neutral invertase of low activity. The distribution of the cell wall-located acid invertase along the root axis appeared to be related to growth. This was not the case for the soluble enzyme. The possible functions of these two enzymes are discussed. |
