Metabolite Production

For a long time, Cannabis sativa has been used for therapeutic and industrial purposes. Due to its increasing demand in medicine, recreation, and industry, there is a dire need to apply new biotechnological tools to introduce new genotypes with desirable traits and enhanced secondary metabolite production. Micropropagation, conservation, cell suspension culture, hairy root culture, polyploidy manipulation, and Agrobacterium-mediated gene transformation have been studied and used in cannabis. However, some obstacles such as the low rate of transgenic plant regeneration and low efficiency of secondary metabolite production in hairy root culture and cell suspension culture have restricted the application of these approaches in cannabis. In the current review, in vitro culture and genetic engineering methods in cannabis along with other promising techniques such as morphogenic genes, new computational approaches, clustered regularly interspaced short palindromic repeats (CRISPR), CRISPR/Cas9-equipped Agrobacterium-mediated genome editing, and hairy root culture, that can help improve gene transformation and plant regeneration, as well as enhance secondary metabolite production, have been highlighted and discussed.

AbstractHairy root culture system is a valuable tool to study the characteristics of gene expression, gene function, root biology, biochemical properties and biosynthesis pathways of secondary metabolites. In the present study, hairy roots were established in Anise hyssop (Agastache foeniculum) via Agrobacterium rhizogenes. Three strains of Agrobacterium rhizogenes (A4, A7 and 9435), were used for induction of hairy roots in four various explants (hypocotyl, cotyledon, one-month-old leaf and five-month-old leaf) of Anise hyssop. The highest frequency of transformation was achieved using A4 strain in one-month-old leaves (51.1%). The transgenic states of hairy root lines were confirmed by PCR (Polymerase chain reaction) method. High performance liquid chromatography analysis revealed that the production of rosmarinic acid (RA) in transformed roots of A. foeniculum was almost 4-fold higher than that of the non-transformed roots. In a separate experiment, hairy roots obtained from one-month-old leaves inoculated with A4 strain, were grown in liquid medium and the effects of different concentrations of salicylic acid (0.0, 0.01, 0.1 and 1 mM) and chitosan (0, 50, 100 and 150 mg L−1) (as elicitor) and sucrose (20, 30, 40 and 50 g L−1) on the growth of hairy roots were evaluated. The results showed that, 30 g L−1 sucrose and 100 mg L−1 chitosan increased the biomass of hairy root cultures and application of salicylic acid reduced the growth of hairy roots compared with control roots.

The importance of chamomile (Chamomilla recutita) inflorescence is widely known in classical and folk medicine, with the largest group of its effective constituents forming the essential oil (chamazulene, a-bisabolol, α-farnesene, trans-β-farnesene, spathulenol, cis/trans-en-in-dicycloethers). Among cultivated species, the Hungarian BK-2 contains more chamazulene in its essential oil than the German Degumil type, which is mainly cultivated for its a-bisabolol. Both components have important antiinflammatory activities. Wild populations can be easily distinguished from cultivated ones by their high amount of bisaboloides, particularly the flower of Hungarian Szabadkígyós wild type, which contained on average 48 % of the biologically active (-)-a-bisabolol. The population of Szabadkígyós has good salt tolerance which is important owing to global warming, because the proportion of saline areas is increasing worldwide. To keep the genome of Szabadkígyós having high (-)-a-bisabolol content, Szőke and research team used biotechnological methods. Sterile plantlets, were infected by Agrobacterium rhizogenes strains #A-4, #15834, #R-1601. The hairy root clones possessing the best growing and biosynthetical potential were multiplied for phytochemical investigations. Pharmacologically important compounds of their essential oils were followed in great detail. The amount of in vitro cultured terpenoids and polyin compounds was compared with that of in vivo plants. GC-MS studies showed that sterile chamomile cultures generated the most important terpenoid and polyin compounds characteristics of the mother plant. Berkheyaradulene, geranyl-isovalerat and cedrol as new components were identified in these sterile cultures. The main component of hairy root cultures (D/400, D/1, D/100 and Sz/400) was tr-b-farnesene and in addition one new compound: a-selinene was identified. Hairy root culture originated from chamomile collected in Szabadkígyós was intensive increased the essential oil content and pharmacological active compounds: (-) -α-bisabolol and β-eudesmol was also synthetized in large quantity. Furthermore, in vitro organized cultures were made from this population to obtain propagation material containing numerous active substances.
