Transgenic Nicotiana Tabacum

We were studied several of antioxidants in transgenic Nicotiana tabacum, plants cultivated in heavy metal polluted soils. The content of phenolic compounds, vitamins C and E in plants increased under these conditions.

Transgenic Nicotiana Tabacum

We conducted a comparative analysis of biochemical parameters for the ascorbate-glutathione cycle in non-transgenic and transgenic Nicotiana tabacum, plants cultivated in heavy metal polluted soils. Transgenic plants had in their genome a bacterial acdS-gene encoding the 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) enzyme. The introduction of elevated concentrations of copper, chromium, and lead ions into the soil promotes induction of the acdS-gene expression and an increase in ACC-deaminase activity in transgenic plants. It was shown the content of ascorbic acid (АА), glutathione, ascorbate peroxidase (АРХ) and glutathione peroxidase (GP) and glutathione reductase (GR) increased in plants under abiotic stress.

We conducted a comparative analysis of biochemical parameters of non-transgenic and transgenic Nicotiana tabacum, plants cultivated in heavy metal polluted soils. Transgenic plants had in their genome a bacterial acdS-gene encoding the 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) enzyme. The introduction of elevated concentrations of copper, chromium, and lead ions into the soil promotes induction of the acdS-gene expression and an increase in ACC-deaminase activity in transgenic plants. It was shown that the content of phenolic compounds (flavonoids), ascorbic acid, the total antioxidant activity of plants increased under abiotic stress.
