| Description
| - Změny v obsazích polyaminů v listech tabáku (Nicotina tabacum L. cv. Wisconsin, 16 h fotoperioda) korelovaly s aktivitami biosyntetických enzymů ornitin- a arginindekarboxylázy i s aktivitou katabolického enzymu diaminoxidázy. Světlo výrazně stimulovalo aktivitu ornitindekarboxylázy i aktivitu diaminoxidázy. Indukce světlem druhého biosyntetického enzymu nebyla pozorována. V práci je diskutována úloha oxidativní degradace a konjugace polyaminů s hydroxyskořicovými kyselinami na udržení hladiny volných polyaminů během 24 h cyklu světlo/tma. (cs)
- Changes in the contents of polyamines (PAs) in tobacco leaves (Nicotiana tabacum L. cv. Wisconsin 38) grown under 16 h photoperiod were correlated with arginine and ornithine decarboxylase (EC 4.1.1.19 [EC] and EC 4.1.1.17 [EC] ) and diamine oxidase (EC 1.4.3.6 [EC] ) activities. The maximum of free and soluble conjugated forms of PAs occurred 1–2 h after the middle of the light period and was followed by two distinct peaks at the end of the light and at the beginning of the dark phase. Putrescine was the most abundant and cadaverine the least abundant PA in both free and PCA-soluble forms. However, cadaverine was predominant in PCA-insoluble conjugates, followed by putrescine, spermidine, and spermine. Both arginine and ornithine decarboxylases are involved in putrescine biosynthesis in tobacco leaves. Light dramatically stimulated the activity of ornithine decarboxylase, while no photoinduction of arginine decarboxylase activity was observed. Ornithine decarboxylase was found mainly in the partic...
