Transformation in Digitalis purpurea L. (Foxglove)
Foxglove (Digitalis purpurea L., common foxglove, D. lanata Ehrh., Grecian foxglove, and other related species) is one of the most commonly used medicinal plants in the world (Trease and Evans 1983). The dried leaves are used as a crude drug and contain a number of cardioactive glycosides, e.g., digitoxin, gitoxin, etc. A large number of reports have been published on tissue culture, regeneration, production, and biotransformation of cardenolides in Digitalis species (for review see Rücker 1988). However, only one paper has appeared on genetic transformation of D. purpurea (Saito et al. 1990a). The efficient transfer and the strong expression of foreign genes in foxglove offer promising possibility of genetic manipulation of secondary metabolism of this plant.
