| Description
| - Diurnal changes of ribulose-1,5- bisphosphate carboxylase/oxygenase (RuBPCO) activity and its content were measured to find the mechanism of RuBPCO activity regulation in Norway spruce needles. Both initial and total RuBPCO activities as well as the activation state had a typical pattern with two peaks in the morning and afternoon, respectively, and a midday depression. On the 19 October, RuBPCO content decreased during the day from 3.1 to 1.4 g m–2, while on the 20 October it was approximately constant both in the morning and in the afternoon (2.7 g m–2). Neither initial nor total activity of RuBPCO copied irradiances. Relatively low morning and evening values of total activities indicate that nocturnal inhibitor CA1P is important in Norway spruce. However, the midday depression of total activity indicates that besides CA1P there function some other inhibitors of RuBPCO. In addition, the diminution of RuBPCO content during the day may indicate repression of its gene expression.

- Denní změny aktivity a množství enzymu ribulosa-1,5- bisfosfat carboxylasa/ oxygenasa (RuBPCO) byly studovány s cílem nalézt mechanismy regulace jeho aktivity v jehlicích smrku ztepilého. Počáteční a celková aktivita RuBPCO i stupeń aktivace vykazovaly typický průběh se dvěma maximy v průběhu dne a polední depresí. 19.10. poklesl obsah RuBPCO během dne z 3.1 na 1.4 g m–2, zatímco 20.10. byl obsah RuBPCO téměř konstantní (2.7 g m–2). Ani počáteční ani celková aktivita RuBPCO nekopírovala aktuální ozářenost v průběhu dne. Relativně nízké hodnoty celkové aktivity v ranních a večerních hodinách naznačují výraznou úlohu regulace aktivity RuBPCO nočním inhibitorem CA1P. Avšak polední deprese celkové aktivity svědčí o tom, že kromě CA1P hrají významnou roli i další denní inhibitory aktivity RuBPCO. Snížení obsahu RuBPCO v průběhu dne může dále svědčit o regulaci na úrovni jeho genové exprese. (cs)
