“…In the serpentine areas on Hokkaido Island, fresh soils create the unusual vegetation pattern of open grasslands and sparse woodlands with a concomitant spruce species tolerant of poor soils (Nakata & Kojima, 1987). Soils with high heavy metal content, low concentrations of macroelements (Horie et al, 2000;Mizuno et al, 2009), and associated microclimates and low soil water content provide stressful habitats for plants (S. Sakaguchi et al, unpublished). Serpentine populations of S. virgaurea have the phenotypic traits of smaller leaves with higher leaf mass per area and higher resource allocation to root systems, which are considered to be selected by environmental stresses in serpentine habitats (S. Sakaguchi et al, unpublished).…”

Early stages of ecological speciation can create populations with an ecology and reproduction timing distinct from those of related populations. Landscape genetic models incorporating environmental heterogeneity and population-specific reproductive traits enable the processes of population genetic differentiation to be inferred. We investigated genome-wide genetic variation in ecotypic populations of Solidago virgaurea sensu lato, a herbaceous plant inhabiting a wide range of habitats (woodlands, serpentine barrens and alpine grasslands) and displaying remarkable variation in flowering time. Simultaneous evaluation of environmental factors revealed an overwhelming effect of soil type differences on neutral genetic differentiation, compared with elevational differences. This result probably reflects the abrupt environmental changes generated by geological boundaries, whereas mountain slopes exhibit clinal changes, facilitating gene exchange between neighbouring populations. Temporal isolation was positively associated with genetic differentiation, with some early-flowering serpentine populations having allele frequencies distinct from adjacent nonserpentine populations. Overall, this study highlights the importance of ecological processes and of evolution of flowering time to promote genetic differentiation of S. virgaurea populations in a complex landscape.

“…Previously we described the accumulation of Ni in lower epidermal cells, especially around the stomata in crystal form in a Japanese Ni hyperaccumulator Thlaspi japonicum [16], the sole Ni hyperaccumulator found in Japan that accumulates about 2500 mg kg -1 Ni in its shoot [14,20], and suggested that transpiration of T. japonicum is one source of Ni hyperaccumulation. This system is predicted to utilize Ni 2+ -transporters for Ni excretion by guttation from the end of veins, and protect the cells from the damage by a high Ni concentration.…”

“…Additionally, serpentine soils have low accumulation of phosphorus, nitrogen and potassium that are essential for plants (Nagy and Proctor 1997). Horie et al (2000) reported that L. takedana accumulates nickel to high level and is tolerant to nickel toxicity. Therefore, L. takedana is adapted to serpentine soils.…”

In the circumboreal region, plants often have extremely-wide species ranges. Lagotis minor-glauca species complex widespread from (sub)arctic Asia to Alaska, however, have two allied narrow endemics in northern Japan: a serpentine plant L. takedana endemic to the Yubari Mountains (Mt. Yubari) and a non-serpentine plant L. yesoensis endemic to the Taisetsu Mountains (Mt. Taisetsu). Elucidating their origins sheds light on drivers for secondary-speciation of widespread circumboreal plants. To infer phylogenetic distinctiveness of two narrow endemics with those related taxa, which contained 25 out of all the 29 species of the genus, chloroplast DNA (cpDNA), nuclear ribosomal (nrITS), two low copy nuclear gene (LCN) markers and genome-wide single-nucleotide polymorphism genotyping (MIG-seq) were used. In the result of cpDNA analyses, the Lagotis minor-glauca species complex formed a clade. Within the clade, L. yesoensis and a portion of L. glauca samples formed a subclade. However, monophyly of each of the four species was not supported. In the results of nrITS and two LCN analyses, L. takedana was monophyletic, while monophyly was not recovered for each L. yesoensis, L. glauca, and L. minor. Based on a Bayesian dating analysis using nrITS data, the age of the most recent common ancestor of L. takedana was Ma (95% confidence interval: 0.05-1.75 Ma). Possible scenario is that an ancestral linage being adapted to serpentine soils migrated into the alpine habitat of Mt. Yubari, that was formed with mountain uplift by the early Pleistocene, and subsequently reproductively isolated from non-serpentine populations and speciated. The contrasting result of L. yesoensis, that was phylogenetically indistinct, is possibly explained by incorrect taxonomy, or alternatively, shallow history and incomplete lineage sorting. In Mt. Taisetsu, massive volcanic eruptions had occurred the Early Pleistocene and even after the last glacial period, suggesting that alpine plants have not migrated into and established populations in Mt. Taisetsu until very recently. To fully resolve the phylogeny of the three species L. yesoensis, L. glauca, and L. minor, further analyses using high resolution molecular markers are needed. The present study illustrated that two narrow endemics in northern Japan diverged from the widespread species include phylogenetically distinctive and indistinctive species, owing to historical orogeny and ecological factors.
