Molecular phylogeny and taxonomy of (Asparagaceae) on Shikoku Island, Japan, including five new species, one new subspecies, and two new status assignments.

Japan has 16 native species of the genus Tratt. (Asparagaceae). A recent study on based on field surveys and molecular phylogenetic analyses resulted in the discovery of six unknown taxa in Kochi Prefecture, Shikoku Island, southwestern Japan.

Molecular phylogeny and taxonomy of the complex (Hydrangeaceae) in western Japan, including a new subspecies of from Yakushima.

According to the contemporary classification of native to Japan, is a polymorphic species including six varieties. We discovered a plant identified as , but morphologically distinct from previously known varieties, in Yakushima island where approximately 50 endemic species are known. To determine the relationship of this plant with previously known varieties, we examined morphology and constructed a highly resolved phylogeny of and its relatives using three chloroplast genomic regions, L, L intron, A-H, and two nuclear genomic regions, ITS1 and ITS2, and Multiplex ISSR genotyping by sequencing (MIG-seq).

A new subspecies of (Caryophyllaceae) from Yakushima, Japan.

An unknown taxon of was discovered in Yakushima, a Japanese island known to harbor several endemic species. To determine the identity of this taxon, this study employed MIG-seq for the reconstruction of a finely resolved phylogenetic tree of the newly discovered taxon, along with some related species of . The results showed that the newly discovered taxon is a relative of .

Validation of (Asparagaceae) as a new species and its phylogenetic affinity.

Molecular phylogenetic studies of (Asparagaceae) and its relatives, which are native to Japan, have been conducted and resulted in a highly resolved phylogeny. Specifically, the relationship of to Hatusima, is investigated. These data include genome-wide SNPs obtained through conducting multiplexed ISSR genotyping by sequencing (MIG-seq).
