Genetic analysis of Japanese and American specimens of Scirpus hattorianus suggests its introduction from North America

Description
Summary:Scirpus hattorianus is a possible alien species in Japan, and a clarification of its unclear taxonomy is required to reveal its origin. It is not known whether the plants initially described from Japan represent the same species distributed in North America. To clarify the origin of the species, we attempted to sequence old specimens collected about 80 years ago using newly designed primer pairs specific for short sequences, including the variable sites. Chloroplast sequences of ndhF were compared among Japanese and North American S. hattorianus , and the closely related species, S. atrovirens, S. flaccidifolius , and S. georgianus . We succeeded in sequencing all samples, and two haplotypes were detected in S. hattorianus : one was unique to the species and the other, detected from specimens potentially collected from the same population as the types, was shared by both North American S. hattorianus and two closely related species, S. atrovirens and S. flaccidifolius . Our results suggest that Japanese S. hattorianus is an alien species that was introduced from North America at least twice.
