PlantID - DNA-based identification of multiple medicinal plants in complex mixtures.

Background: An efficient method for the identification of medicinal plant products is now a priority as the global demand increases. This study aims to develop a DNA-based method for the identification and authentication of plant species that can be implemented in the industry to aid compliance with regulations, based upon the economically important Hypericum perforatum L. (St John's Wort or Guan ye Lian Qiao).

DNA reviews: DNA identification following CBRN incidents.

Chemical, biological, radioactive, or nuclear (CBRN) incidents can occur due to accident or deliberate action, and may result in substantial loss of life. Whatever the cause, the requirement for identification of the deceased may necessitate the removal of contaminated samples to a DNA laboratory for processing. This review looks at the potential types of CBRN that may result in the requirement for DNA identification of the deceased and investigates the potential risks and difficulties associated with processing samples of this type.
