Abstract
The present invention provides methods of inducing somatic embryogenesis in tissue cultures derived from varieties of Taxus. In addition, the present invention provides methods of obtaining taxol, or precursors thereof, using in vitro propagated somatic embryo tissues.
Claims6
A method of producing taxane ring-containing compounds from somatic embryos of Taxus which are capable of producing said compounds, comprising the steps of:
- culturing embryos from the genus Taxus in a culture medium under conditions which produce somatic embryos;
- and
- isolating said taxane ring-containing compounds from said embryos or said medium.
A method of producing taxane ring-containing compounds from embryogenic tissue cultures of Taxus which are capable of producing said compounds, comprising the steps of:
- culturing embryos from the genus Taxus in a culture medium under conditions which produce embryogenic tissue;
- and
- isolating said taxane ring-containing compounds from said embryogenic tissue or said medium.
