| Research Abstract |
Pantropical Plants with Sea-drifted Seeds (PPSS) were studied by means of molecular population genetics to clarify how their distribution ranges were established over littoral areas all over the tropics. Geographic structure and phylogenetic relationships were studied in some representative plants of PPSS (genus Rhizophora, Canavalia rosea, Vigna marina, for example) . Cross-species comparison of results revealed 1) the presence of common geographic barriers that prevent gene flow by long distance dispersal by sea-drifted seeds, and 2) patterns of speciation influenced by seed dispersability.
