Initial Results

Catharanthus roseus hairy roots induced by Agrobacterium rhizogenes get potential to apply to many fields. The suitable conditions for culturing depend on each hairy root line. In shaken liquid media in dark at 25 oC, VIN002-12 and VIN005-07 hairy root lines had the best growth in hemi-concentrated Gamborg’B5 media while VIN072-15 and VIN077-09 lines showed the best growth in in hemi-concentrated White media. The appropriate initial pH of medium for the lines was in range of 5.7–6.5. The hairy root lines used 2–5% sucrose as an optimal source of carbon for their growth. In selected conditions, the growth kinetics curves showed the end of exponential phase at the 28th day of culture with VIN005-07 and VIN072- 15 lines whereas at the 35th day with VIN002-12 and VIN077-09 lines. The initial results are quite possible to produce biomass for researches on four hairy root lines in the future.

Agrobacterium Rhizogenes Strains

Shoots of Salvia officinalis, a medicinally important plant, were infected with Agrobacterium rhizogenes strains ATCC 15834 and A4 which led to the induction of hairy roots in 57% and 37% of the explants, respectively. Seven lines of hairy roots were established in WP liquid medium under light and dark conditions. The transformed nature of the root lines was confirmed by polymerase chain reaction using rolB and rolC specific primers. Transformed root cultures of Salvia officinalis showed variations in biomass and rosmarinic acid production depending on the bacterial strain used for transformation and the root line analyzed. Both parameters (growth and rosmarinic acid content) of ATCC 15834-induced lines were significantly higher than the A4-induced lines. The maximum accumulation of rosmarinic acid (about 45 mg g-1 of dry weight) was achieved by hairy root line 1 (HR-1) at the end of the culture period (45D50 days). The level was significantly higher than that found in untransformed root culture (19 mg g-1 of dry wt).

Common Purslane

Common purslane (Portulaca oleracea L.) is an annual plant as one of the natural sources for noradrenaline hormone. In this research, hairy root culture of purslane was established by using Agrobacterium rhizogenes strain ATCC 15834. In the following, Box-Behnken model of response surface methodology (RSM) was employed to optimize B5 medium for the growth of P. oleracea L. hairy root line. According to the results, modelling and optimization conditions, including sucrose, CaCl2.H2O, H2PO4 and NO3-/NH4+ concentrations on maximum dry weight (0.155 g) and noradrenaline content (0.36 mg.g-1 DW) was predicted. These optimal conditions predicted by RSM were confirmed the enhancement of noradrenaline production as an application potential for production by hairy root cultures.

The aim of the study was to obtain transformed roots ofRhaponticum carthamoidesand evaluate their phytochemical profile. Hairy roots were induced from leaf explants by the transformation ofAgrobacterium rhizogenesstrains A4 and ATCC 15834. The best response (43%) was achieved by infection with A4 strain. The effects of different liquid media (WPM, B5, SH) with full and half-strength concentrations of macro- and micronutrients on biomass accumulation of the best grown hairy root line (RC3) at two different lighting conditions (light or dark) were investigated. The highest biomass (93 g L−1of the fresh weight after 35 days) was obtained in WPM medium under periodic light. UPLC-PDA-ESI-MS3and HPLC-PDA analyses of 80% aqueous methanol extracts from the obtained hairy roots revealed the presence of eleven caffeoylquinic acids and their derivatives and five flavonoid glycosides. The production of caffeoylquinic acids and their derivatives was elevated in hairy roots grown in the light. Only light-grown hairy roots demonstrated the capability for the biosynthesis of such flavonoid glycosides as quercetagetin, quercetin, luteolin, and patuletin hexosides. Chlorogenic acid, 3,5-di-O-caffeoylquinic acid and a tentatively identified tricaffeoylquinic acid derivative were detected as the major compounds present in the transformed roots.
