The process of callus induction, organogenesis and plantlets regeneration of Camptotheca acuminata Decne is reported. The highest growth rate of callus was observed on MS medium with 1 mg l−1 NAA, 1 mg l−1 kinetin and 60 g l−1 sucrose. All tissues and organs developed in vitro contain camptothecin and 10-hydroxycamptothecin. The presence of(More)
We have analysed the effect of some culture conditions and media components on callus growth rate and production of taxanes in callus of Taxus × media var. Hatfieldii. For callus induction and maintenance a Gamborg B5 medium and a White - Rangaswamy medium (WR) with different modifications were used. On an improved WR medium (containing 10 μM picloram) the(More)
This study assessed the effect of two precursors (l-phenylalanine and p-amino benzoic acid) used alone or in combination with methyl jasmonate, on the growth and accumulation of paclitaxel, baccatin III and 10-deacetylbaccatin III in hairy root cultures of Taxus x media var. Hicksii. The greatest increase in dry biomass was observed after 4 weeks of(More)
Ergoline alkaloids (syn. ergot alkaloids) are constituents of clavicipitaceous fungi (Ascomycota) and of one particular dicotyledonous plant family, the Convolvulaceae. While the biology of fungal ergoline alkaloids is rather well understood, the evolutionary and biosynthetic origin of ergoline alkaloids within the family Convolvulaceae is unknown. To(More)
In Taxus cuspidata callus, vanadyl sulfate (10 mg l−1) induced a high (146 μg g−1 dry wt) production of 10-deacetylbaccatin III in comparison to 7 μg g−1 dry wt of the control. The content of paclitaxel in this species increased from 16 μg g−1 to 74 μg g−1 dry wt when 20 mg phenylalanine l−1 was used. In T. media, p-aminobenzoic acid induced the highest(More)
Hairy root cultures of Taxus × media var. Hicksii were established by infection of the plantlets with the Agrobacterium rhizogenes strain LBA 9402. The paclitaxel accumulation in hairy root cultures increased after 100 μM methyl jasmonate treatment from 69 to 210 μg g−1 dry wt while the 10-deacetybaccatin III content was not affected by the elicitor.
Transformed root cultures of Coluria geoides Ledeb. were established with the use of Agrobacterium rhizogenes LBA 9402. Both normal and transformed root cultures were investigated for their growth and yield of eugenol. Normal roots were grown in B5 medium-supplemented with 0.2 mg l-1 of kinetin and 0.2 mg l-1 of 1-naphthaleneacetic acid (NAA). Hairy roots(More)
This report describes the regeneration of plants from callus cultures of caraway, Carum carvi L. Callus of hypocotyl origin was maintained on medium containing Murashige and Skoog salts with Nitsch and Nitsch vitamins in the presence of 0.3 mg · l(-1) 2,4-D. Formation of somatic embryos was induced with suspension cultures once 2,4-D had been removed.(More)
Hairy root cultures of Lithospermum canescens were established using three strains of Agrobacterium rhizogenes: ATCC 15834, LBA 9402 and NCIB 8196. Eight lines resulting from infection with A. rhizogenes ATCC 15834 demonstrated sufficient biomass increase and were submitted to further investigations. The contents of acetylshikonin (ACS) and(More)
Taxus cuspidata and Taxus media var. Hicksii contain paclitaxel, among other taxoids, on the surface of the needles. These compounds were removed by 5-s dipping of the needles in water just below its boiling point at 96 degrees C and at 60 degrees C and 40 degrees C. Taxus cuspidata contained a fourfold higher concentration of paclitaxel than Taxus media(More)
