title: Assessing phylogenetic relationships of Lycium samples using RAPD and entropy theory.
abstract: OBJECTIVE
  To evaluate the phylogenetic relationships among related species of Lycium samples.
  
  
  METHODS
  Random amplified polymorphic DNA (RAPD) fingerprinting and lab-on-a-chip electrophoresis techniques were used to analyze the characteristics of Lycium species. Seven species and 3 varieties of Lycium were studied. Based on RAPD fingerprint data obtained from 11 primers, we proposed a new index, called dispersivity, using entropy theory and projection methods to depict the diversity of the DNA fingerprints.
  
  
  RESULTS
  Using the proposed dispersivity, primers were sorted and the dendrograms of the 7 species and 3 varieties of Lycium were constructed synthetically by merging primer information.
  
  
  CONCLUSIONS
  Phylogenetic relationships among Lycium samples were constructed synthetically based on RAPD fingerprint data generated from 11 primers.
