Název v původním jazyce

The effect of plant cytokinin hormones on the production of ethylene, nitric oxide, and protein nitrotyrosine in ageing tobacco leaves

Popis výsledku v původním jazyce

In the present study we employed transgenic plants with genetically increased or decreased levels of cytokinins. We investigated the effects of cytokinin level on the production of ethylene, a plant hormone with suggested role in senescence, and the production of nitric oxide, potentially important signalling and regulatory molecule. The production of these gases was followed in the course of leaf development and senescence. The production of ethylene and nitric oxide is under genetic control of other genes than those involved in regulation of senescence. The difference in basic ethylene and NO levels in different tobacco cultivars was higher than their changes in senescence. Our results do not indicate a direct link between ethylene production and cytokinin levels. In accordance with the previous studies we observed a decreased production of NO in senescent leaves. Low cytokinins level was associated with increased NO production during leaf development. Protein nitrotyrosine proved to
