A wide range of cadmium concentrations (from 4 to 200 μM for seedlings and up to 2 mM for germinating kernels) was used to assess Cd toxic effects on maize (Zea mays L.) plants at the different developmental stages: germinating kernels, seedlings (4–9 days), and juvenile plants (34 days). Cd accumulation in plant organs was followed, and its lethal(More)
The review presents current literature data on the mechanisms maintaining plant water balance or those providing for tolerance to its disturbance. We consider the processes enabling the changes in the transpiration rate under water deficit due to changes in stomatal conductivity and the changes in the rate of leaf growth, as well as the role of hydraulic(More)
The ability of brassinosteroids, such as 24-epibrassinolide (EBL) to increase the resistance of oilseed rape plants (Brassica napus L.) to salt stress (175 mM NaCl) was investigated along with the possible mechanisms of their protective action. Seedlings were grown for three weeks on the Hoagland-Snyder medium under controlled conditions. The experimental(More)
In the present study, the influence of 50 and 100 µM CuSO4 was investigated starting from 3 h till 72 h treatment of 4-weeks Brassica napus plants. High CuSO4 concentrations in nutrient medium resulted in the rapid copper accumulation in plants, especially in roots, much slower and to lower degree in leaves. Copper excess induced early decrease in the leaf(More)
Transformation by genes of various ion transporters is a tool to study plant salt tolerance mechanisms. In this work, the gene of a vacuolar NHX antiporter HvNHX3 was introduced in two potato Solanum tuberosum L. cultivars, Yubiley Zhukova and Skoroplodny-7. The binary vector pCambia-HvNHX3 was made and used for transformation. This vector carries HvNHX3(More)
