Novel enzymes involved in the biosynthesis of plant secondary metabolites have been discovered in our laboratory from both differentiated plants and in vitro cultures of Thai medicinal plants. The discovered enzymes included (1) geranylgeraniol-18-hydroxylase from Croton sublyratus containing plaunotol, an anti-peptic ulcer diterpenoid, (2) dopamine-secologanin condensing enzymes from Alangium ...
The pharmacological treatment of pain has very ancient origins, when plant-derived products were used, including mandrake extracts and opium, a dried latex obtained from Papaver somniferum. In the XVI and XVII centuries opium came into the preparation of two compounds widely used for pain relief: laudanum and Dover's powder. The analgesic properties of extracts of willow bark were then recogniz...
MADS-box genes are crucial regulators of floral development, yet how their functions have evolved to control different aspects of floral patterning is unclear. To understand the extent to which MADS-box gene functions are conserved or have diversified in different angiosperm lineages, we have exploited the capability for functional analyses in a new model system, Papaver somniferum (opium poppy...
The involvement of PISTILLATA (PI) and APETALA (AP) transcription factors in the development of floral organs has previously been elucidated but little is known about their upstream regulation. In this investigation, two novel mutants generated in Papaver somniferum were analyzed--one with partially petaloid sepals and another having sepaloid petals. Progeny from reciprocal crosses of respectiv...
خشخاش ایرانی، کبیر یا طناز با نام علمی .Papaver bracteatum Lindl به عنوان منبع جدید مواد خام جهت تولید کدیین و داروهای ترک اعتیاد مطرح است. این گیاه بومی ایران بوده و در شمال و غرب ایران رویش دارد. با توجه به امکان کشت غیرقانونی گونه Papaver somniferum، کشت خشخاش ایرانی در کشور با محدودیت همراه بوده است و علی‌رغم تنوع فراوان این گونه در ایران، تاکنون مورد توجه قرار نگرفته است. خشخاش ایرانی فاقد...
Recently, the NADPH-dependent short-chain dehydrogenase/reductase (SDR) salutaridine reductase (E.C. 1.1.1.248) implicated in morphine biosynthesis was cloned from Papaver somniferum. In this report, a homology model of the Papaver bracteatum homolog was created based on the x-ray structure of human carbonyl reductase 1. The model shows the typical alpha/beta-folding pattern of SDRs, including ...
The archaeobotanical samples analysed derive from a well-preserved well dated to the Early Iron Age (Hallstatt) according to pottery found in the sampled layers and on a radiocarbon dating (720-520 cal B.C.) of the wooden construction of the well. Cultivated plants (Panicum miliaceum, Linum usitatissimum, Papaver somniferum and Camelina sativa) were recorded in relatively small numbers whereas ...
