2.3.1.107 medicine production of therapeutically valuable terpenoid indole alkaloids 706200 2.3.1.107 agriculture treatment with cold plasma upregulates the expressions of deacetylvindoline O-acetyltransferase gene by an average of 7.8 times. Plasma priming induces activities of phenylalanine ammonia-lyase, catalase (about twofold) and peroxidase (31%). The plasma-treated seedlings contain higher concentrations of alkaloids 756520 2.3.1.107 drug development vincristine and vinblastine are secondary metabolites from Catharanthus roseus with very high pharmacological value that are used in treating cancer. However, these compounds are synthesised in Catharanthus roseus plants with very low content. The vincristine contents of four transgenic lines expressing the CrDAT gene are increased from 162.59% to 247.76% compared with the non-transgenic plants 765187
