Recent plastid genome (plastome) studies of legumes (family Fabaceae) have shown that this family has undergone multiple atypical plastome evolutions from each of the major clades. The tribe Desmodieae belongs to the Phaseoloids, an important but systematically puzzling clade within Fabaceae. In this study, we investigated the plastome evolution of Desmodieae and analyzed its phylogenetic signaling.

Premise Of The Study: (Fabaceae) is a narrowly endemic species restricted to mountain valleys of southern Korea. To investigate its fine-scale genetic diversity and differentiation in Korea, we developed polymorphic microsatellite markers.

Methods And Results: Sixteen polymorphic microsatellite markers were developed from Illumina MiSeq data.

has limited distribution in the coastal regions of Korea and Japan and is named as a vulnerable halophyte in the Red List of Japan. The complete plastid genome of is 151,989 bp long, and is composed of large single-copy (83,492 bp) and small single-copy (18,121 bp) regions plus two inverted repeats (25,188 bp each). The plastid genome encodes 130 genes, including 8 rRNAs, 37 tRNAs, and 83 protein-coding genes.

Traditionally, the tribe Sophoreae sensu lato has been considered a basal but also heterogeneous taxonomic group of the papilionoid legumes. Phylogenetic studies have placed Sophoreae sensu stricto (s.s.

The dynamic changes in land configuration during the Quaternary that were accompanied by climatic oscillations have significantly influenced the current distribution and genetic structure of warm-temperate forests in East Asia. Although recent surveys have been conducted, the historical migration of forest species via land bridges and, especially, the origins of Korean populations remains conjectural. Here, we reveal the genetic structure of Lespedeza buergeri, a warm-temperate shrub that is disjunctively distributed around the East China Sea (ECS) at China, Korea, and Japan.

Premise Of The Study: We developed microsatellite primers for Lespedeza maritima (Fabaceae), a Korean endemic shrub, and conducted cross-amplifications for closely related species.

Methods And Results: We produced 28 polymorphic microsatellite markers through reference mapping of 300-bp paired-end reads obtained from Illumina MiSeq data. For 47 individual plants from two populations, the total alleles numbered two to 13, and observed and expected heterozygosities ranged from 0.

Premise Of The Study: Microsatellite primers were developed for Pedicularis ishidoyana (Orobanchaceae), an endangered and hemiparasitic plant that is narrowly endemic to Korea. Because its populations are threatened by loss of suitable habitat, conservation efforts are required.

Methods And Results: We developed polymorphic microsatellite loci through reference mapping of 300-bp paired-end reads obtained from Illumina MiSeq data.

We sequenced the complete plastid genome (plastome) for Piper kadsura, a woody vine endemic to East Asia. This species is part of the largest genus within Piperaceae and its genome is almost identical to its congener P. cenocladum.

To evaluate the population genetics structure as a means of devising conservation strategies, we developed microsatellite primers for Sophora koreensis, a narrowly endemic and endangered species in Korea. Thirteen polymorphic microsatellite markers were developed in Korean populations of S. koreensis.

Neolitsea sericea is an evergreen broad leaved tree in the warm-temperate regions of East Asia. This area is a hotspot for plant species richness and endemism caused by dynamic changes in land configuration during the Quaternary. However, the historical migration of such evergreen tree species is still poorly understood.

Premise Of The Study: Microsatellite primers were developed for the alpine plant Leontopodium japonicum to evaluate its population genetics structure as a means for devising future conservation strategies.

Methods And Results: Ten polymorphic microsatellite markers were developed in Korean populations of L. japonicum.
