Abstract
Phytoremediation is an environmentally friendly and inexpensive method for cleaning soils contaminated by heavy metals (HM). For phytoremediation using superaccumulater plants capable of accumulating HM is promising. The using of synthetic pseudophytochelatine genes ( pph ) can potentially increase the availability of HM for plants. The article describes the creation of the vector pCambia1305.1- pph6 for obtaining of transgenic model tobacco plants. As a result, at 100 μM concentration of cadmium in the soil, transformed plants expressing the pph6 gene accumulated cadmium 35% more than the control plants.
