Genetic Studies in the Opium Poppy

Genetic 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...

AFLP Analysis of Opium Poppy

There are several different DNA analysis procedures that have been used to identify and characterize plant Amplified restriction fragment length polymorphic (AFLP) DNA cultivars to determine genetic diversity. Each procedure analysis was performed on leaf samples of 40 accessions of opium poppy (Papaver somniferum L.) and two other control genera (Pahas it own requirements, sensitivity, and rel...

Secrets of the opium poppy revealed.

Studies concerning drugs of abuse have made major contributions in defining the circuitry, as well as cellular and molecular substrates that underlie certain behaviors. Opiate drugs for example, have revealed important insights concerning pain perception and reward. Up to the late 1960s, opiate drugs were suspected to work by mysteriously perturbing lipid membrane structure. We now know the fol...
