| Abstract: | The cytokinin-autonomous strain (As) of tobacco callus differs from the original cytokinin-dependent strain (D) and from the cytokinin- and auxin-autonomous strain (A4) by a significantly lower activity of glucose-6-phosphate dehydrogenase (G-6-PDH). Changes in the total G-6-PDH activity were associated with differences in the number of G-6-PDH isozymes. The As strain contained only one isozyme, four isozymes were found in D and A4 strains. |
