• Even in cases in which geographic isolation appears to have driven the speciation of regional endemics, range shifts during the Pleistocene climatic oscillations may also have influenced their evolutionary history. Elucidating speciation history...
Various photoreceptors in plants are used to monitor important environmental light signals and regulate plant development. Despite their functional importance, recent studies have demonstrated that red/far-red absorbing phytochromes or blue/UV-A a...

The Pleistocene was characterized by a cyclic pattern of cold and warm climatic periods, or climatic oscillations, which caused fluctuations in the distributions of organisms. This resulted in drastic changes in demography, thereby accelerating th...
Given that plants are sessile organisms, traits involved in adapting to local environments and/or in monitoring the surrounding environment, such as having photoreceptors, are significant targets of natural selection in plant evolution. To assess ...

According to previous phylogeographic studies, high mountains at low latitudes are important areas for the study of the evolutionary history of arctic-alpine plants in surviving the Pleistocene climatic oscillations. To evaluate this hypothesis, w...
Molecular phylogeography has inferred the history of differentiation between regions and/or among populations following the Pleistocene climatic oscillations, mostly based on the genetic structure of organelle DNA. However, such genetic structure ...

Previous phylogeographic studies of arctic-alpine plants have partly elucidated that alpine areas at the southernmost edges of their distribution have been one of the most important areas for the survival of populations through Quaternary climatic...
Aim: We aimed to elucidate how the current geographic distribution of alpine plants in the Japanese archipelago was shaped during Quaternary climatic oscillations, using Potentilla matsumurae as a case study. According to previous phylogeographic ...

Phylogeographic analyses using chloroplast DNA (cpDNA) variation were performed for Pedicularis ser. Gloriosae (Orobanchaceae). Eighty-one plants of 18 populations of 6 species (P. gloriosa, P. iwatensis, P. nipponica, P. ochiaiana, P. sceptrum-ca...
Molecular phylogeographic studies have revealed the genetic patterns and glacial-interglacial history of many plant and animal species. To infer the Quaternary history of alpine plants in the Japanese archipelago, which is poorly known, we investi...
