Molecular Characterization of Opium Poppy (Papaver somniferum) Germplasm
Problem statement: The medicinal value of opium poppy (2n = 22, Papaver somniferum L.) is due to presence of more than two dozen alkaloids. The genetic origin and diversity of cultivars used in the breeding collection is not fully known. To evaluate the genetic diversity of the 24 germplasm currently cultivated in the state to provide genetic information about heterogeneity, using RAPD and ISSR...
متن کاملStudying Morphine Biosynthesis Using Transgenic Opium Poppy (Papaver somniferum L.)
Opium poppy (Papaver somniferum L.) produces a large variety of isoquinoline alkaloids. The aim of this investigation is to understand the regulation of biosynthesis and the ecological function of the alkaloids in the plant. Agrobacterium-mediated transformations of opium poppy were used to introduce the berberine bridge enzyme cDNA bbe 1 in the antisense orientation into seedling explants. Aft...
متن کاملGrowth, Opium Gum Yield, and Photoperiod Response of Five Opium Poppy Accessions
Flowering time, growth, and opium gum yield from five seed sources (T, L, B1, B2, B3) of opium poppy (Papaver somniferum L.) collected from different latitudes in three Southeast Asian countries were determined. Plants were grown in six growth chambers at a 11-, 12-, 13-, 14-, 15-, or 16-hour photoperiod with a 12-hour, 25/20 °C thermoperiod. Flower initiation was observed under a dissecting mi...
متن کاملMolecular Genetic Analysis of an O-Methyltransferase of the Opium Poppy Papaver somniferum
Isoquinoline alkaloids are a large class of compounds derived from the amino acid L-tyrosine containing many physiologically active members. Among the isoquinoline alkaloids, morphine is one of the pharmaceutically important members that is still derived from the plant that produces it, the opium poppy Papaver somniferum. P. somniferum produces over 80 alkaloids derived from L-tyrosine. We have...
متن کاملGenetic analysis of capsule and its associated economic traits in opium poppy (Papaver somniferum L.).
Four single crosses (VG20 x SGE48, SGE48 x SG35II, VG26 x SG35II, and SG35II x VG20) in opium poppy (Papaver somniferum L.) were analyzed to study the gene actions involved in the inheritance of quantitative traits, namely plant height, branches/plant, capsules/plant, peduncle length, capsule index, stigmatic rays, straw yield/plant, and morphine content. Simple additive, dominance, and epistat...
