Method for increasing content of camptothecin in camplotheca acuminata calluses by adopting camplotheca acuminata transgene aoc

InactiveCN101831456AIncrease the content of camptothecinVector-based foreign material introductionTransgeneBiology
The invention relates to a method for increasing the content of camptothecin in camplotheca acuminata calluses by adopting a camplotheca acuminata transgene aoc, belonging to the technical field of biology. The method comprises the following steps of: cloning a gene aoc from camplotheca acuminata, constructing a plant expression vector containing the gene aoc and mediating with agrobacterium tumefaciens to introduce the gene aoc to camplotheca acuminata cells and regenerating the calluses; detecting the integration and expression conditions of the foreign target gene aoc by PCR (Polymerase Chain Reaction) and semiquantitative RT-PCR (Reverse Transcription-Polymerase Chain Reaction); measuring the camptothecin content in the camplotheca acuminata calluses by a high performance liquid chromatography detector; and scanning the transgenic camplotheca acuminata calluses, the camptothecin content of which is increased. The content of the camptothecin in the transgenic camplotheca acuminata calluses obtained by the invention is obviously increased. The method for increasing the content of the camptothecin in the culture of camplotheca acuminata cells is significant for solving the problem of deficient drug sources of the camptothecin and meeting the demands of large-scale industrialized production of pharmaceutical industry.
