in complex with Cu2+ enhances activity
additional information
-
auxin treatment induces AtCKX6 gene and increases enzyme level
-
additional information
expression of the DhCKX gene is induced in roots, shoot apices and leaves, but not in stems, after treatment with 0.02 mM 6-benzylamino-purine

-
additional information
enzyme is induced by cytokinins
-
additional information
-
dark-treatment results in high increase in CKX activity, addition of kinetin in dark-treated leaves results in high increase of CKX activity compared with dark-treated leaves without kinetin
-
additional information
-
cytokinin-induced up-regulation of enzyme activity, e.g. by N6-benzylaminopurine application on the plant leaf or callus surface leads to about 2.5fold increased activity after 4 h, overview
-
additional information
-
cytokinins induce enzyme activity, predominantly of the glycosylated isozyme
-
additional information
-
elevated temperature around 35°C increases enzyme activity
-
additional information
cultivation in the presence of gibberillic acid increases enzyme activity in leaves of cv. Scinado
-
additional information
isozymes TaCKX5a/b, TaCKX6a, and TaCKX2a expression are induced by pathogen infection, i.e. by Fusarium sp. or Puccinia sp.
