Název v původním jazyce

Cytokinin-induced activity of antioxidant enzymes in transgenic Pssu-ipt tobacco during plant ontogeny

Popis výsledku v původním jazyce

Cytokinin (CKs) content and activities of antioxidant enzymes were examined during plant ontogeny of transgenic Pssu-ipt tobacco. Control non-transgenic (Nicotiana tabacum L. cv. Petit Havana SR1) and transgenic Pssu-ipt tobacco were both grown either asgrafts on SR1 rootstocks or as rooted plants. Both control plant types showed a decline in total content of CKs with proceeding plant senescence, while both transgenic plant types exhibited a significant enhancement of CKs content throughout the ontogeny with maximal values in the later stages of plant development. Significantly higher portion of O-glucosides was found in both transgenic plant types compared to SR1. In transgenic plants, zeatin and zeatin riboside were predominated type of CKs. Generally, Pssu-ipt tobacco exhibited elevated activities of antioxidant enzymes compared with control SR1 tobacco particularly in the later stages of plant development. The enhancement of peroxidase activities was observed in transgenic grafts
