Background: Iranin poppy (Papaver bracteatum Lindl.) belongs to Papaveraceae family which has important alkaloids such as thebain. Objective: Investigation of genetic diversity and population structure of Iranian poppy populations from Alborz Mountains. Methods: Total DNA from 36 genotypes (12 individuals from each population) were extracted by doyle method. Thebaine of capsules were assayed...
BACKGROUND Horizontal gene transfer (HGT) plays a major role in speciation and evolution of bacteria and archaea by controlling gene distribution within an environment. However, information that links HGT to a natural community using relevant population-genetics parameters and spatial considerations is scarce. The Great Salt Lake (Utah, USA) provides an excellent model for studying HGT in the c...
