Silene vulgaris (Moench) Garcke (Caryophyllaceae) is widely distributed in North America and contains bioactive oleanane-type saponins. In order to investigate in vitro production of triterpenoid saponins, hairy root cultures of S. vulgaris were established by infecting leaf explants with five strains of Agrobacterium rhizogenes (LBA9402, R1000, A4, 13333, and 15834). The A. rhizogenes strain LBA9402 had an infection of 100% frequency and induced the most hairy roots per plant. Methyl jasmonate (MeJA)-induced changes in triterpenoid saponins in S. vulgaris hairy roots were analyzed. Accumulation of segetalic acid and gypsogenic acid after MeJA treatment was 5-and 2-fold higher, respectively, than that of control root. We suggest that hairy root cultures of S. vulgaris could be an important alternative approach to the production of saponins.

Six triterpene acids identified as betulinic, oleanolic, ursolic, 3-epimaslinic, alphitolic and euscaphic acids have been isolated from a dichloromethane extract of hairy root cultures of Ocimum basilicum L. (Lamiaceae). These cultures were obtained by genetic transformation using Agrobacterium rhizogenes. The extract as well as the isolated compounds were evaluated for their hepatoprotective activity by measuring their effect on the oxidative stress status of liver, induced by carbon tetrachloride, in albino rats and in liver homogenate in vitro. All tested compounds displayed hepatoprotective activity comparable to oleanolic and ursolic acids.

AbstractHairy root cultures are an efficient tool for the biotechnological production of plant metabolites and a convenient experimental model for analyzing the effect of various compounds on plant metabolism. In contrast to many other types of in vitro plant cultures, hairy roots do not require an external supply of phytohormones to the medium. Consequently, plant growth regulators such as auxins and cytokinins are rarely used as elicitors in hairy root in vitro cultures; however, they can strongly influence plant defense responses. The aim of this study was to investigate the influence of two auxins: natural indole-3-acetic acid (IAA) and synthetic 1-naphthaleneacetic acid (NAA), as well as two cytokinins: natural kinetin and synthetic 6-benzylaminopurine (BAP) at a concentration of 0.75 mg/L on the metabolism of sterols and triterpenoids in Calendula officinalis hairy roots. Auxins prevented the accumulation of triterpenoid saponins (oleanolic acid glycosides), while cytokinin BAP increased their accumulation by 17% and their release into the culture medium by a factor of 10. Other cytokinins and kinetins increased the sterol levels by 17%, the level of stigmasterol by 15%, and the level of isofucosterol by 7 times.

AbstractHairy root cultures of lettuce (Lactuca sativa L.) were obtained by inoculation of cotyledonary leaves of in vitro lettuce seedlings (cvs. Nansen and Ljubljanska ledenka) with Agrobacterium rhizogenes A4M70GUS. Approximately in 96.7% cvs. Nansen and in 91.2% Ljubljanska ledenka inoculated explants produced hairy root when they were incubated on Murashige and Skoog (MS) half-strength medium without plant growth regulators. A total of 54% of all hairy root cultures expressed GUS activity. Every hairy root represented an independent transformation event. Line Ljubljanska ledenka 18 showed the highest biomass (5.5 times the biomass of control root). A PCR analysis of the genomic DNA confirmed the presence of marker and target genes in 15 hairy roots examined.
