We conducted a phylogeographic study on the alpine plant Arcterica nana based on haplotypes of chloroplast DNA. Using a sequence of approximately 1,071 bp of intergenic spacers of chloroplast DNA (trnT-L, psbB-psbF), we detected 13 haplotypes among 193 individuals sampled from 22 populations. Two dominant haplotypes were distributed over the entire range of this species in Japan, and we found several local private haplotypes. An analysis of molecular variance (AMOVA) indicated no geographic structure within the haplotype distribution. In addition, the genetic distance was not related to its corresponding geographic distance (Mantel test: r=-0.049, P=0.66), indicating a homogeneous geographic structure throughout the entire distribution range in the Japanese archipelago. The most parsimonious explanation for this geographic structure is that A. nana spread across its extant distribution range in the Japanese archipelago through a recent range expansion event. However, this pattern is inconsistent with the previous phylogeography of Japanese alpine plants, which reveals that haplotypes in central Honshu are differentiated from those in more northern regions. Arcterica nana may have experienced a different history from other alpine plants, suggesting that the history of Japanese alpine flora may include at least two different geographic radiation patterns.
