Abstract
S Oiki T Kawahara K Inoue M Ohara M Maki Random Amplified Polymorphic DNA RAPD Variation among Populations of the Insular Endemic Plant Campanula microdonta Campanulaceae Annals of Botany Volume 87 Issue 5 May 2001 Pages 661–667 https//doiorg/101006/anbo20011389RAPD variation was examined in nine populations of Campanula microdonta Koidz endemic to the Izu Islands Japan Ninetyeight bands were obtained for all populations 94 of which were polymorphic at least within a population Shannons H values were calculated these have frequently been used in RAPD studies to estimate genetic diversity The values within populations did not correlate with the allozyme gene diversity estimated by a previous study or with distance from the Japanese mainland The possible reasons for this discrepancy are different selection regimes between the two markers higher RAPD mutation rates and each markers different coverage of genomes Cluster analysis of genetic similarities suggested that colonization of each island probably occurred once except for Miyake Island where immigration has occurred at least twice Copyright 2001 Annals of Botany CompanyFor correspondence at c/o Dr Masashi Ohara Laboratory of Ecology and Genetics Division of Bioscience Graduate School of Environmental Earth Science Hokkaido University Kita 10 Nishi 5 Sapporo 0600810 Japan Fax +81 11 706 2225 email oikihdolphincutokyoacjp
