Callus Tissues

The capacity of alkaloid synthesis was examined in embryogenic callus tissues of Turkish opium poppy, Papaver somniferum L cv. office-95. Eight months old cultures grown in hormone-free MS were examined for alkaloid content. They were found to produce codeine at a level of 1.2 x 10-2, the baine 2.5 x 10-3, noscapine 2.2 x 10-3, morphine 1.6 x 10-3 and papaverine 5.2 x 10-4 % FW.Key words: Papaver somniferum, Embryogenic callus, AlkaloidsDOI = 10.3329/ptcb.v16i1.1098Plant Tissue Cult. & Biotech. 16(1): 1-4, 2006 (June)

Growth Development

The effects of increasing concentrations of heavy water (2H2O) on the growth, development, morphology, and transpiration patterns in Nicotiana tabacum L. were studied throughout the life cycle of the plant. The higher deuterium levels caused a marked reduction in size and flowering, together with extensive tissue necrosis. These observations are consistent with the literature on the effects of deuterium on plant development. The present study showed a deleterious effect of deuterium on alkaloid production, associated with heightened transpiration rates and decreased fractionation of carbon isotopes in photosynthesis. All of the observed effects are consistent with the established view of deuterium as a nonspecific chaotropic agent, whose effects are evident at every level of plant organization.

Causal Factors

The ability of fungi parasitic on Papaver somniferum L. capsules, and capsule enzymes to degrade morphine, codeine, and thebaine was studied, with the aim of determining the causal factors involved in alkaloid losses from the mature capsule during rainy periods. When whole, mature capsules were inoculated with fungal spore suspensions and incubated for 21 days, Alternuria alternutu decreased dry matter and morphine yields by 12 and 48% respectively. Ernbellisia sp. caused a 30% decrease in morphine yield, but Dendryphion penicillatum and Cladosporiurn cladosporioides had no effect. Codeine and thebaine yields were not affected. Acetone powder extracts showed that mature capsule enzymes caused morphine and thebaine losses in the order of 10 and 50%, but only in the presence of p-cresol, a substrate for polyphenoloxidase. These findings, indicating the ability of fungi and enzymes to cause alkaloid losses from mature capsules during moist periods, are discussed with regard to commercial alkaloid production.
