This work was to characterize the generation of nitric oxide (NO) in Taxus yunnanensis cells exposed to low-energy ultrasound (US) and the signal role of NO in elicitation of plant defense responses and secondary metabolite accumulation. The US sonication (3.5-55.6 mW/cm(3) at 40 kHz fixed
Cell culture ofTaxus wallichiana Zucc (= T. baccata ssp wallichiana Zucc. Pilg.) (Himalayan yew) has been established and taxol-producing cell lines selected by cell line cloning. Cell line NC110 derived from needle leaf of a 40-year-old tree growing in Darjeeling Himalayas produced 0.018% taxol in
This work was to characterize the generation of nitric oxide (NO) in Taxus yunnanensis cells induced by a fungal-derived cerebroside and the signal role of NO in the elicitation of plant defense responses and taxol production.
Suspension cultures ofTaxus yunnanensis cells were inoculated with cells of different culture ages (12-24 days) at various densities [50-250 g fresh weight (fw)/l], and treated (on day 7) with a mixture of elicitors, including Ag(+), chitosan and methyl jasmonate. The biomass productivity (during
Pestalotiopsis microspora was isolated from the inner bark of a small limb ofHimalayan yew, Taxus wallachiana, and was shown to produce taxol in mycelial culture. Taxol was identified by spectroscopic and chromatographic comparisons with authentic taxol. Optimal taxol production occurred after 2-3
