Successful management of the synthesis of secondary metabolites of essential oil plants is the basis for the economic growth of the essential oil industry. Against the backdrop of a growing global population and a decrease in land available for cultivation, simple and effective ways to increase the content of certain components in essential oils are becoming increasingly important. Selection is no longer keeping pace with market needs, which stimulates the search for faster methods to control the biosynthesis of secondary metabolites. In this article, using the genus Lavandula as an example, we will consider the prospects for use of antisense oligonucleotides (ASO), oligoilators, to rapidly increase the concentration of valuable components in essential oil. This article discusses the use of unmodified ASOs as regulators of plant secondary metabolism to increase the synthesis of individual valuable components, presenting a completely new way to increase the yield of valuable substances based on unique nucleotide sequences. The proposed approach is effective, affordable, safe, and also significantly reduces the time needed to obtain plants that synthesize the required concentrations of target substances. Oligoilators can the used along with oligonucleotide insecticides in complex formulations used for green agriculture. Further investigation is needed to determine maximum economic efficiency of this approach.

The main problem in creating anti-coronavirus vaccines that target mainly proteins of the outer membrane of the virus remains the rapid variability of the RNA genome of the pathogen that encodes these proteins. In addition, the introduction of technologies that can provide affordable and fast production of flexible vaccine formulas that easily adapt to the emergence of new subtypes of SARS-CoV-2 is required. Universal oligonucleotide vaccine can take into account the dynamics of rapid changes in the virus genome, as well as be synthesized on automatic DNA synthesizers in large quantities in a short time. In this brief report, the effectiveness of four phosphorothioate constructs of the La-S-so type oligonucleotide vaccine will be evaluated for the first time on transgenic mice [B6.Cg-Tg (K18-ACE2)2]. In our primary trials, the oligonucleotide vaccine increased the survival rate of animals infected with SARS-CoV-2 and also reduced the destructive effects of the virus on the lung tissue of mice. The obtained results show the perspective of the development of vaccine constructs of the La-S-so type for the prevention of coronavirus infections, including those caused by SARS-СoV-2.
