Abstract: | Lignans are found in a wide variety of plant species. The lignan podophyllotoxin is of special interest, since its derivatives like e.g. etopophos® are used in anticancer therapy. As chemical synthesis of podophyllotoxin is not yet economic, it still has to be isolated from wild growing Podophyllum species, some of which are considered to be endangered species. Therefore plant in vitro cultures may serve as alternative sources for podophyllotoxin and for other types of lignans as well. This review describes the establishment of plant cell and tissue cultures for lignan production and the experiments to improve product yields by changing the cultivation parameters, addition of elicitors and feeding of precursors. It also summarizes the use of plant cell and organ cultures to study the biosynthesis of lignans on enzymological level.Abbreviations: DOP – deoxypodophyllotoxin; LARI – lariciresinol; MATAI – matairesinol; 6MPTOX – 6-methoxypodophyllotoxin; PINO – pinoresinol; PTOX – podophyllotoxin; SECO – secoisolariciresinol |
