In vitro production of secondary metabolite using Atropa komarovii Bline&Shal (Solanaceae) hairy root culture via Agrobacterium rhizogenes ATCC15834

E-p-methoxycinnamic acid (MCA) is one of the main active constituents of Scrophularia buergeriana Miquel and has hepatoprotective, anti-amnestic, and neuroprotective activities. For studying in vitro production of MCA, we established a hairy root culture of S. buergeriana by infecting leaf explants with Agrobacterium rhizogenes R1000, and tested the growth and MCA production of these cultures using different strengths of media and concentrations of auxins. Hairy roots grown in half-strength MS medium showed the highest levels of growth (10.3 g/l) as well as MCA production (0.83 mg/100 g dry weight). Hairy root culture with the treatment of 0.5 mg/l IBA produced the highest amount of dry weight (11.8 g/l) and MCA (1.26 mg/100 g dry weight) production. These results demonstrate that the hairy root culture of S. buergeriana is a valuable alternative approach for the production of MCA. .

Long-chain polyisoprenoid alcohols built from several up to more than 100 isoprenoid units are common constituents of all living organisms. They were found mostly in plants, bacteria, yeasts and mammalian cells. In vitro hairy root culture of Coluria geoides was obtained from plants transformed with Agrobacterium rhizogenes. Growth was optimal at 0.75% (w/v) glucose and at 22 °C. Dry samples of roots were extracted and lipid content was analysed by HPLC. According to our estimation, polyprenols are accumulated in roots of C. geoides cultivated in vitro as a mixture of several prenologues with the dominating prenol composed of 16 isoprenoid units. The content of polyprenols in tissue was approx. 300 μg/g of dry weight.

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.

Background: Hairy root culture has been widely used in the production of metabolites in dicotyledons, and a large number of food crops and medicinal plants in monocotyledons need to be developed, but there are many difficulties in the induction of hairy roots in monocotyledons. The purpose of this paper is to introduce the inducing methods, influencing factors and application of hairy roots in monocotyledons, and to promote the development of hairy root system in monocotyledons. Methods: The mechanism of action of Agrobacterium rhizogenes and the current situation of hairy root induction, induction methods and influencing factors of monocotyledons were summarized so as to provide convenience for efficient acquisition of hairy root of monocotyledons. Results: Monocotyledons are not easy to produce phenols, cells are prone to lignification, adverse differentiation and selective response to Agrobacterium rhizogenes strains. It is proposed that before induction, plant varieties and explants should be selected, and different infection strains should be screened. In the process of hairy root induction, exogenous inducers such as acetosyringone can be added. Although these factors can provide some help for the induction of hairy roots in monocotyledons, we still need to pay attention to the disadvantages of monocotyledons from dicotyledons at the cellular level. Conclusion: A large number of food crops and medicinal plants are monocotyledons. Hairy root culture can be used to help the breeding and production of medicinal substances. Therefore, it is necessary to pay attention to the selection of varieties and explants, the selection of Agrobacterium rhizogenes and the addition of acetosyringone in the process of hairy root induction so as to improve the production efficiency and facilitate the development and utilization of monocotyledons.
