Callus and cell suspension cultures of opium poppy have, so far, not been seen to develop typical laticifers as displayed, for instance, in micrographs of shoots from seedlings and regenerants by Thureson-Klein (1970) and Nessler and Mahlberg (1977, 1979). Laticifer-like cells were demonstrated foxP. bracteatum cell cultures by Kut-chan et al. (1983). Absence of typical laticifers was often cited as the reason for failure to show occurrence of thebaine or codeine in poppy cell cultures. Today one may propose that accumulation of low amounts of morphinan alkaloids do not require latex and respective vessels. Indeed, other parts of the plant besides latex have...
