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 کاملGenetic studies on collar rot resistance in opium poppy (Papaver somniferum L.).
The collar rot disease has been reported recently and occurs at the 10-12-leaf stage of plants of opium poppy. Infected plants topple down and dry prematurely due to fast rotting at the collar region. The inoculum for this study was multiplied on the cornmeal-sand culture. Genetic ratios were calculated by the chi-square test. Inheritance studies on this disease show a monogenic pattern of segr...
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 کاملThe floral androcarpel organ (ACO) mutation permits high alkaloid yields in opium poppy Papaver somniferum
Isolation of a recessive aco (androcarpel organ) mutation in opium poppy Papaver somniferum, is described. The aco (aco aco) mutant plants form androcarpels in place of inner whorl stamens in their flowers. The abnormal flowers are self-fertile, as stamens in the outer whorl are normal. In aco mutant the calyx, corolla and syncarpous gynoecium are formed like in the wild type ACO plants. The an...
