Conventional tobacco, traditionally used as a raw material for making cigarettes, has now become the subject of innovative scientific research. Using modern genetic modification methods, scientists have been able to give this plant the ability to synthesize five types of psychedelic substances that were previously produced by different organisms in nature.
Psychedelics occur in nature in various forms and origins: for example, psilocybin is produced by “ magic mushrooms ”, the ingredients for ayahuasca are extracted from tropical plants, and bufotenine is a secret of frogs. Now, tobacco has become a versatile bioreactor capable of synthesizing these substances through skillful genetic manipulation, opening up new horizons in bioengineering.
Scientists have been studying the biochemical processes involved in the formation of hallucinogens in various plants and organisms for over sixty years. They have uncovered detailed biochemical pathways for some psychedelic substances, among which psilocybin occupies a special place.
One of the important discoveries was a study published two years ago led by Asaf Aharoni of the Weizmann Institute of Science. They mapped out the complete chemical pathway for the formation of the hallucinogen in peyote cacti, starting with the amino acid L-tyrosine, a breakthrough in understanding the natural synthesis of psychedelics.
A new contribution to the field comes from Aharoni and biochemist Paula Berman of the Volcani Center for Agricultural Research, who studied the mechanisms of synthesis of N,N-dimethyltryptamine (DMT), the key psychedelic compound found in the traditional ayahuasca drink, which is prepared by Amazonian shamans from the chakruna plant (Psychotria viridis), a relative of coffee.
The scientists analyzed DMT levels in various plants and chose two species with high levels of the substance for detailed study - Psychotria viridis and the Australian tree Acacia acuminata. They studied the activity of genes in tissues that produce DMT to identify the enzymes responsible for synthesis.
The researchers identified two key genes - PvTDC2 and PvNMT1 - and introduced them into tobacco. This gave the modified plants the ability to produce DMT. Paula Berman noted that the chemical reactions in this process are quite simple, which makes the synthesis more predictable and understandable for further use.
Since tobacco is naturally rich in tryptophan, an amino acid needed for the synthesis of psychedelics, the researchers tried to expand the range of substances produced. They added the ability to produce psilocybin and its precursor, as well as bufotenine and 5-methoxy-DMT, hallucinogens secreted by the Sonoran Desert toad (Incilius alvarius) from glands behind its eyes.
However, they faced a problem with low levels of 5-methoxy-DMT production. To address this challenge, the team used AlphaFold3, an artificial intelligence tool that predicts the three-dimensional structure of proteins based on amino acid sequences. This helped them identify the cause of the enzyme's inefficient functioning.
After targeted mutation of the enzyme, the amount of 5-methoxy-DMT in tobacco increased 40-fold, which is a significant breakthrough in increasing the productivity of synthesis.
The most ambitious experiment was the creation of a tobacco plant capable of simultaneously producing five different psychedelics. This unique achievement is scientifically novel, but its practical utility is limited by the low concentrations of each substance.
Andrew Jones, a bioengineering expert at the University of Miami who was not involved in the research, says that industrial production of psychedelics will likely involve using microbes in the lab, but he acknowledges the interest of some enthusiasts in the possibility of simultaneously producing multiple psychedelics in tobacco.
The authors emphasize that before genetically modified tobacco can become a reliable source of pharmaceutical psychedelics, a number of complex tasks must be solved. Among them is the development of effective methods for processing the plant and extracting active substances in sufficient quantity and quality.
Today, a more realistic option remains the use of microbes to produce DMT and other psychoactive compounds on an industrial scale, which provides a controlled and scalable process.
This research demonstrates that even traditional crops such as tobacco can be transformed into efficient producers of complex psychedelic substances. It opens up new possibilities for bioengineering by combining genetic technologies with natural biochemical processes.
While the technology for genetically modified tobacco that produces psychedelics has great potential, it also requires careful safety and ethical consideration. It is important to consider the potential risks associated with the use of such substances, as well as legal restrictions in different countries.
These studies have shown that genetically modified tobacco can be a versatile bioreactor for the synthesis of various psychedelics. This not only opens up new prospects in the pharmaceutical industry, but also emphasizes the importance of an interdisciplinary approach in bioengineering.
Further steps in this area will require both scientific and regulatory efforts to ensure the safety and efficacy of new biotechnologies.
