Abstract: Population genetic variation in the tropical moss species Acanthorrhynchium papillatum was evaluated using nucleotide sequences of the second Internal Transcribed Spacer (ITS2) region of the nuclear ribosomal DNA. High levels of variation were observed at both nucleotide and haplotype levels using this marker, indicating that the various populations in southern Peninsular Malaysia and Singapore have been genetically isolated to a large extent over time despite short spatial distances between some of the populations. Sequence analysis suggests that ITS2 diversity arises from high rates of mutation at this locus. In common with earlier results from microsatellite marker analysis, these results demonstrate that the genetic diversity of mosses may be high, as with higher plant species. Overall, relatively lower levels of diversity were seen in ITS2 loci compared to microsatellite markers. Thus the ITS2 region can be a useful additional DNA marker for analysing genetic diversity in this moss species. © British Bryological Society 2013.
