Nonuniform concerted evolution and chloroplast capture: heterogeneity of observed introgression patterns in three molecular data partition phylogenies of Asian Mitella (saxifragaceae).
TLDR
This finding indicates that the use of multiple molecular tools has the potential to reveal detailed organismal evolution processes involving interspecific hybridization, as an individual locus varies greatly in its potential to introgress between species. Expand
Phylogeny of Aspleniaceae Inferred from rbcL Nucleotide Sequences
TLDR
RbcL sequences of 25 species and 2 varieties of Aspleniaceae with various leaf and rhizome morphologies are determined, and a phylogenetic analyses with the following conclusions are conducted: 1) leaf shape is not congruent with rbcL phylogeny in AsPleniaceae; 2) rhizomes morphology reflects rbcC phylogeny; 3) naturally occurring hybrids are generated only between closely related species and thus reflect the rbcS phylogeny.

Phylogeography of the component species of broad-leaved evergreen forests in Japan, based on chloroplast DNA variation
TLDR
This study investigated the intraspecific phylogeographic patterns of lucidophyllous forests in Japan and surrounding areas and suggested the existence of additional important refugia along the Pacific coast of Japan during the glacial ages. Expand
Phylogeny of Osmundaceae Inferred from rbcL Nucleotide Sequences and Comparison to the Fossil Evidences
TLDR
The phylogenetic analysis concluded that Osmunda cinnamomea is the most basally positioned species in Osmundaceae, and it can be called as “a living fossil” because a fossil species with almost the same morphology as this species was recorded from the Triassic. Expand
Cryptic species and host specificity in the ectomycorrhizal genus Strobilomyces (Strobilomycetaceae).
TLDR
This study analyzed both nuclear and mitochondrial DNA sequences from Strobilomyces fungi and obtained evidence that what were previously described as four species can be grouped into 14 distinct lineages, suggesting that these lineages might be distinct biological species. Expand
Comparative phylogeography of red maple (Acer rubrum L.) and silver maple (Acer saccharinum L.): impacts of habitat specialization, hybridization and glacial history
TLDR
The sharing of cpDNA and chloroplast simple sequence repeat (cpSSR) haplotypes in areas of geographic overlap provides evidence of introgression, which led to an increase in haplotype diversity in both species, and to novel phylogeographic structure in A. rubrum. Expand
Comparative phylogeography of four component species of deciduous broad-leaved forests in Japan based on chloroplast DNA variation
TLDR
A phylogeographic study of four tree species growing in Japanese deciduous broad-leaved forests based on chloroplast DNA variations found that the forests in eastern Japan separately expanded from each of the refugia along the Sea of Japan-side or along the Pacific Ocean-side, and those in southwestern Japan retreated and moved to high altitudes from Each of the continuous forests.

Molecular systematics of the genus Astragalus L. (Fabaceae): Phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacers and chloroplast gene ndhF sequences
TLDR
Comparative sequencing of internal transcribed spacers and 5.8S gene of nuclear ribosomal DNA was carried out to examine phylogenetic relationships among subgenera and sections of Old World Astragalus as well as the recent segregate genera Barnebyella and Ophiocarpus to confirm earlier studies that shows A. vogelii is allied with the genera Colutea and Oxytropis rather than with any AStragalus species. Expand
Systematics and evolutionary biology of the fern genusHymenasplenium (Aspleniaceae)
TLDR
This paper considered the evolution of various phenetic characters based on a molecular phylogenetic tree which was recently obtained from sequence comparisons ofrbcL. Expand
