cell suspension culture | analysis of in vivo activity of ornithine decarboxylase in three different cell lines of Daucus carota, namely N1 (embryogenic), F1 (non-embryogenic), and O3 (habituated and non-embryogenic), during growth and somatic embryogenesis. The enzyme activity in the presence of various levels of auxin (2,4-dichlorophenoxy acetic acid) is highest during periods of active cell division. During somatic embryo development, the enzyme activity is highest during globular stage formation. Stage-specific activity of ODC, overview | Daucus carota | - |

General Information | Comment | Organism |
---|---|---|
metabolism | ornithine decarboxylase is a key enzyme in the biosynthesis of putrescine and thus polyamines | Daucus carota |
additional information | ODC in vivo activity varies with auxin concentration in the medium, overview | Daucus carota |
physiological function | the enzyme is active during growth and somatic embryogenesis and contributes to polyamine biosynthesis, its activity lead to putrescine and, subsequently, to spermidine and spermine formation | Daucus carota |
