Transgenic medicinal plants as producers of bioactive substances

The paper covers the questions of secondary metabolite modulation in medicinal plants by means of gene engineering. It is demonstrated that cutting-edge tools of contemporary biotechnology tools made it possible to manage the biosynthesis of important bioactive substances, modify the secondary metabolism, enabling plants to synthesize and produce new compounds, as well as eliminate metabolic pathways of synthesizing harmful substances. Currently, large-scale production of bioactive substances (BAS) requires highly productive plants to produce them. Applying methods of gene engineering to medicinal plants is a promising way to reduce the resource consumption and increase their productivity, quality and the product’s marketability [1]. Traditional growing and collecting techniques are challenged by resource shortage, environmental damage, etc. [2]. Gene engineering helps to increase pest, disease and herbicide resistance, gain greater yields and higher BAS content [3]. Using transgenic medicinal plants (TMP) as BAS producers in the pharmaceutical industry is crucial for metabolic engineering. Current research of the secondary metabolism modulation in TMP enables to modify the key B
