A study of somatic embryogenesis and rhizogenesis and their influence on production of morphinan alkaloids on two species of opium poppy is presented. We identified the ratios of auxin and cytokinin that caused somatic embryogenesis and rhizogenesis in hypocotyl and cotyledons of Papaver somniferum album and Papaver orientale splendidissimum. The hypocotyls and cotyledons both show somatic embr...

Based on sequence data from ITS rDNA, cox1 and cox2, six Peronospora species are recognised as phylogenetically distinct on various Papaver species. The host ranges of the four already described species P. arborescens, P. argemones, P. cristata and P. meconopsidis are clarified. Based on sequence data and morphology, two new species, P. apula and P. somniferi, are described from Papaver apulum ...

The effort of this work was to prove whether there exists any relation between stress factors caused by content of cadmium and zinc, and content and composition of opium alkaloids codeine, morphine, narcotine (noscapine) and papaverine contained in poppy seeds and capsules (Papaver somniferum L.) in 14 samples of 8 varieties cultivated in 8 localities in 2003.

Oripavine is the major alkaloid of Papaver orientale. It is an important intermediate in the biosynthesis of morphine alkaloids. Recently, new Papaver somniferum strains have been developed which accumulate thebaine and oripavine, but not morphine and codeine. Therefore, the chemistry of oripavine has been studied intensively to synthesize opioid pharmaceuticals such as oxymorphone, naloxone an...

Karyomorphology of 30 species of Papaver L. (Papaveraceae) and in situ localization of rDNA sites on chromosomes of P. somniferum was used to establish phylogenetic affinities, ancestry and chromosomal variation during speciation. A simple biometrical parameter, the ‘Dispersion Index’, was employed to facilitate quantitative evolutionary gradation between the closely related karyotypes that fal...

medicinal use of the opium poppy (papaver somniferum l) has ancient history, but the isolation of morphine was not described until the early nineteenth century. morphine is the most important alkaloid of opium poppy in the last 50 years. in the morphine pathway has been reported to generate morphine in this species, codm has a crucial role as the gene coding the enzyme responsible for demethyla...
