| Abstract | Random amplified polymorphic DNAs (RAPDs) and inter-simple sequence repeats (ISSRs) markers were used to analyze genetic structure of 30 accessions of alien weed Crassocephalum rubens that were sampled from its introduced regions in Southeast Asia. The study found that C. rubens currently only spreads in Myanmar and Thailand. Using 20 RAPD primers and 20 ISSR primers, 90 RAPD bands and 43 ISSR bands were produced respectively. Quite considerable genetic variability does exist among different of C. rubens populations. However, lack of clear geographical structure of genetic variation among populations suggested that human-mediated, long-distance seed dispersal may have contributed to its weak geographical genetic structure of C. rubens in Southeast Asia |
