    Weed Compounds from Guide to A Cannabinoids: Bioactive 13

    The inducible expression will limit the negative effects caused by the toxicity of the accumulating cannabinoids during the growth of the transformed plant cells as more thoroughly described in the next section.

    Workflow showing the achievements in green and potential future approaches in light blue to produce cannabinoids in cultures of Cannabis , as well as other plant hosts. In addition to the genetic engineering approach, plant cell suspension cultures can be elicited to boost the production of secondary metabolites. The literature is rich in examples concerning the increased expression of secondary metabolites in plant cells elicited with different factors reviewed recently by Ncube and Van Staden, Both biotic and abiotic stress factors can indeed be used to re-direct the plant metabolism: In hemp suspension cells, elicitation with biotic and abiotic elicitors did not induce an increase in cannabinoids Flores-Sanchez et al.

    It is here worth mentioning the effect of a so far neglected element, silicon Si. Despite being a non-essential element for plant growth, Si is known to increase plant vigor and to alleviate the effects of exogenous stresses Epstein, Very recently Si was shown to alleviate the effects of salt stress and to induce the production of chlorogenic acid in Lonicera japonica Gengmao et al.

    Given the stimulatory effects that Si has on plant metabolism, it is interesting to further investigate, from a molecular perspective, the effects of Si supplementation on Cannabis secondary metabolite production. Cyclodextrins have also been used in plant cell suspension cultures to enhance the production of various non-polar metabolites such as stilbenes Yang et al.

    They are known to form inclusion complexes with lipophilic compounds, including cannabinoids Hazekamp and Verpoorte, , in their hydrophobic cavity, thereby improving metabolite solubility in an aqueous environment. It would therefore be worth investigating the effect of cyclodextrins on the production of the non-polar cannabinoids in hemp suspension cell cultures. For example synthetic biology could be used to recreate the cannabinoid biosynthetic pathway in heterologous plant cells via the expression of THCAS, together with the upstream enzymes involved in the synthesis of CBG, i.

    Examples for the occurrence of metabolons exist in plants for pathways involving, e. Entire metabolic pathways can be engineered via the use of synthetic metabolons enabling the association of enzymes in close proximity: One possible way to assemble a synthetic metabolon is via the use of a scaffolding protein enabling the association of the enzymes Singleton et al. The assembly of multimodular constructs for expression in plants is no longer an insurmountable challenge, thanks to the development of methods like the Gateway-mediated cloning reviewed by Dafny-Yelin and Tzfira, , Golden Gate Binder et al.

    When cannabinoids are produced in heterologous plant hosts, toxicity effects have to be taken into account, as it was shown that THCA and CBGA cause cell death via apoptosis in cells of Cannabis and tobacco BY-2 Sirikantaramas et al. For plant cell suspension cultures cultivated in bioreactors, the in situ product removal via a two-phase culture system might be useful to favor the accumulation of the toxic metabolites produced in sites which are separated from the cells Cai et al.

    The use of adsorbents in the culture medium can not only sequester the toxic compounds, but also stimulate the secondary metabolite biosynthesis Cai et al. This approach has been recently proposed in A. The authors induced the formation of an artificial compartment generated by membranes deriving from endocytosis and the endoplasmic reticulum-vacuole trafficking via the expression of a truncated SNARE protein, AtSYP The creation of an artificial compartment can be used for the production of cannabinoids, because it can trap and stabilize the toxic secondary metabolites until extraction is performed, in a manner analogous to what discussed for artemisinin.

    Hemp is a unique versatile plant, which can provide high biomass quantities in a short time. Hemp stem is used as a source of woody and bast fibers for the construction and automotive industries, while hemp seeds are used as a source of dietary oil and hemp leaves and flowers as a source of bioactive components.

    To date, more than phytochemicals have been described in hemp Gould, , and their pharmacological properties appear to go much beyond psychotic effects, with the capacity to address needs like the relief of chemotherapy-derived nausea and anorexia, and symptomatic mitigation of multiple sclerosis. Nature has already provided a large source of new molecules and new skeletons. Cannabis presents a colossal potential for enlarging the library of bioactive metabolites.

    Compounds can be obtained from hemp trichomes, cell suspension cultures, hairy root systems, or via the biotransformation of THCA or CBDA using fungal, bacterial, or plant cells Akhtar et al. Apart from the importance of studies focused on improving Cannabis genetic transformation, it is necessary to know more about the regulatory mechanisms involved in secondary metabolite production in C. For example enzymological and structural studies will help devise protein engineering approaches to improve the catalytic functions of key enzymes Taura et al.

    However, further studies would still be needed to elucidate other key genes involved in biosynthetic pathways of, for instance, less-abundant cannabinoid derivatives. For that purpose, the combination of metabolomics with genome-based functional characterizations of gene products would provide an accelerated path to discovering novel biosynthetic pathways to specialized metabolites.

    Indeed, the functions of numerous genes have been identified and characterized through the correlation of gene expression and metabolite accumulation Sumner et al. Classical approaches used focused on the spatial and temporal distribution of the targeted phytochemicals and on the plant transcriptome, as influenced by the developmental stage and environmental stresses.

    With respect to the resurgence of interest in Cannabis phytochemicals nowadays, the results of such studies will be soon available. CA was involved in the review writing, J-FH was involved in manuscript refinement, and GG initiated the idea of the review and was involved in the manuscript writing. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

    Abstract Cannabis sativa L. Introduction The current climatic and economic scenario pushes toward the use of sustainable resources to reduce our dependence on petrochemicals and to minimize the impact on the environment.

    A Source of Fibers with Antibacterial Properties Plant lignocellulosic biomass is an abundant renewable resource, which can provide biopolymers, fibers, chemicals and energy Guerriero et al. Open in a separate window. Their Production Pathways and Myriad of Biological Activities Numerous chemicals are produced in hemp through the secondary metabolism. Phytocannabinoids Phytocannabinoids represent a group of C21 or C22 for the carboxylated forms terpenophenolic compounds predominantly produced in Cannabis.

    Table 1 Summary of the concentrations in cannabinoids found in different parts of the hemp plants, in vitro hairy roots, and some commercial medicinal products. The most recent references have been used, when available. Health Benefits Linked to Cannabinoids The pharmacology of phytocannabinoids has previously been reviewed elsewhere Pacher et al. Adverse Health Effects of Cannabinoids As mentioned earlier, the recreational and medical use of Cannabis as well as of THC and other synthetic cannabinoids have also been associated with numerous side effects.

    Terpenes Terpenes form the largest group of phytochemicals, with more than molecules identified in Cannabis Rothschild et al. Health Benefits Associated with Terpenes Terpenes are lipophilic compounds that easily cross membranes and the blood-brain barrier in particular Fukumoto et al. Phenolic Compounds Phenolic compounds, also known as phenylpropanoids, constitute one of the most widely distributed group of secondary metabolites in the plant kingdom.

    Health Benefits Associated with Phenolic Compounds In plants, phenolic compounds may act as antioxidants under certain physiological conditions and, thereby, protect plants against oxidative stress. Synergistic and Antagonistic Effects Between Phytochemicals It is now well accepted that the health benefits of fruits, vegetables and other plant foods are due to the synergy or interactions between the different bioactive compounds or other nutrients present in the whole foods, and not to the action of a sole compound Liu, Small Factories of Phytochemicals Trichomes are epidermal protuberances covering the leaves, bracts and stems of plants and some of them, like the glandular trichomes, are capable of secreting or storing secondary metabolites as a defense mechanism.

    Cannabis In Vitro Propagation and Transformation The cultivation of Cannabis is severely regulated in many countries; therefore alternative in vitro growth techniques are receiving a lot of attention. Hairy Root Cultures for the Production of Cannabinoids An additional system offering interesting applications for the industrial production of compounds showing pharmaceutical effects in humans is the hairy root system, a type of Agrobacterium -transformed plant tissue culture used to study plant metabolic processes.

    Cannabis Cell Suspension Cultures for the Production of Cannabinoids Plant cell suspension cultures offer important advantages, as they can be transformed and then cultivated in bioreactors for the production of useful metabolites Weathers et al.
