The first complete plastid genome (plastome) of the largest angiosperm genus, Astragalus, was sequenced for the Korean endangered endemic species A. mongholicus var. nakaianus. Its genome is relatively short (123,633 bp) because it lacks an Inverted Repeat (IR) region. It comprises 110 genes, including four unique rRNAs, 30 tRNAs, and 76 protein-co...
A new distribution of Dalbergia hupeana has been reported at Mt. Yudal in Mokpo-si, Korea. It was previously thought to be restricted to China, but is now recognized as a new addition to Korean flora. Species identification was confirmed according to morphological characteristics and DNA sequences. The genus Dal-bergia is clearly distinguished from...
Forests dominated by broad-leaved evergreen trees cover a narrow zone of the southern coast of Korea as well as warm-temperate and subtropical regions of Japan. However, little is known about their establishment history, especially in Korea. Endemic Quercus acuta grows in Korea and Japan. We evaluated its genetic diversity, population structure, an...
To clarify the taxonomic position for Astragalus nakaianus and provide correct scientific name for A. mongholicus cultivar in South Korea, we examined external morphological characters and sequence variations from ITS and five cp non-coding DNA regions. Genetic structure was also analyzed for 61 individuals from three populations using nine microsa...
The butterfly‐shaped keel flower is a highly successful floral form in angiosperms. These flowers steer the mechanical interaction with bees and thus are hypothesized to accelerate pollinator‐driven diversification. The exceptionally labile evolution of keel flowers in Papilionoideae (Fabaceae) provides a suitable system to test this hypothesis.

The butterfly shaped keel flowers are among the most successful pollination syndromes in angiosperms. These flowers steer the mechanical interaction with bees and thus are hypothesized to accelerate pollinator driven diversification. The highly labile evolution of keel flowers in Papilionoideae (Fabaceae) provides a suitable system to test this hyp...
Similar to the global phenomenon, many plant species endemic to Korean limestone karst forests are at risk of extinction due to human intervention. Zabelia tyaihyonii is a familiar shrub, called "Hardy abelia" and "Fragrant abelia" growing in the karst forests of Korea, where it is one of the most threatened species. We investigated the genetic str...
Paraphlomis koreana (Lamiaceae) was newly named and added to Korean flora in 2014. Paraphlomis belongs to the tribe Paraphlomideae, along with Ajugoides and Matsumurella. However, a recent study has suggested that P. koreana is morphologically similar to Matsumurella chinensis, making them difficult to distinguish from each other. Therefore, we aim...
Medicago truncatula is a model legume that has been extensively investigated in diverse subdisciplines of plant science. Medicago littoralis can interbreed with M. truncatula and M. italica; these three closely related species form a clade, i.e. TLI clade. Genetic studies have indicated that M. truncatula accessions are heterogeneous but their taxo...
Comprising 501 genera and around 14,000 species, Papilionoideae is not only the largest subfamily of Fabaceae (Leguminosae; legumes), but also one of the most extraordinarily diverse clades among angiosperms. Papilionoids are a major source of food and forage, are ecologically successful in all major biomes, and display dramatic variation in both f...
Plant nuclear genomes harbor sequence elements derived from the organelles (mitochondrion and plastid) through intracellular gene transfer (IGT). Nuclear genomes also show a dramatic range of repeat content, suggesting that any sequence can be readily amplified. These two aspects of plant nuclear genomes are well recognized but have rarely been lin...
In this study, we sequenced the complete plastid genome (plastome) of Neolitsea aciculata, an evergreen broad-leaved tree endemic to East Asia, a woody component of East Asian warm-temperate and subtropical forests across China, Korea, and Japan. The plastome of N. aciculata is assembled as a single contig (152,722 bp). A large and a small single c...
The dynamic evolution of mitochondrial gene and intron content has been reported across
the angiosperms. However, a reference mitochondrial genome (mitogenome) is not available in
Rubiaceae. The phylogenetic utility of mitogenome data at a species level is rarely assessed. Here,
we assembled mitogenomes of six Damnacanthus indicus (Rubiaceae, Rubio...
We here sequenced the complete plastid genome (plastome) of Vaccinium japonicum (Ericaceae), a deciduous broad-leaved shrub endemic to East Asia. This species has considerable practical economic value. The plastome of V. japonicum is assembled as a single contig (187,213 bp). A large single copy (104,637 bp) and a small single copy (3,000 bp) of th...
Plant specific mitoviruses in the ‘genus’ Mitovirus (Narnaviridae) and their integrated sequences (non-retroviral endogenous RNA viral elements or NERVEs) have been recently identified in various plant lineages. However, the sparse phylogenetic coverage of complete plant mitochondrial genome (mitogenome) sequences and the non-conserved nature of mi...
The plastid genome (plastome), while surprisingly constant in gene order and content across most photosynthetic angiosperms, exhibits variability in several unrelated lineages. During the diversification history of the legume family Fabaceae, plastomes have undergone many rearrangements, including inversions, expansion, contraction and loss of the...

We are reporting the complete plastid genome (plastome) of Quercus acuta, an evergreen broad-leaved oak endemic to East Asia. This species is important for maintaining the warm-temperate evergreen forest biome in East Asia. The Q. acuta plastome is 160,522 base pairs (bp) long, with two inverted repeat (IR) regions (25,839 bp each) that separate a...
The inverted repeat (IR) lacking clade (IRLC) is a monophyletic group within the Papilionoideae subfamily of Fabaceae where plastid genomes (plastomes) do not contain the large IR typical of land plants. Recently, an IRLC legume, Medicago minima, was found to have regrown a ~9 kb IR that contained a number of canonical IR genes, and closely related...
Jeju Island is located at a marginal edge of the distributional range of East Asian evergreen broad-leaved forests. The low genetic diversity of such edge populations is predicted to have resulted from genetic drift and reduced gene flow when compared to core populations. To test this hypothesis, we examined the levels of genetic diversity of margi...
The genus Trifolium is the largest of the tribe Trifolieae in the subfamily Papilionoideae (Fabaceae). The paucity of mitochondrial genome (mitogenome) sequences has hindered comparative analyses among the three genomic compartments of the plant cell (nucleus, mitochondrion and plastid). We assembled four mitogenomes from the two subgenera (Chronos...
Background:
Organelle genome studies of Fabaceae, an economically and ecologically important plant family, have been biased towards the plastid genome (plastome). Thus far, less than 15 mitochondrial genome (mitogenome) sequences of Fabaceae have been published, all but four of which belong to the subfamily Papilionoideae, limiting the understandi...
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...
The plant genome comprises a coevolving, integrated genetic system housed in three subcellular compartments: the nucleus, mitochondrion, and the plastid. The typical land plant plastid genome (plastome) comprises the sum of repeating units of 130–160 kb in length. The plastome inverted repeat (IR) divides each plastome monomer into large and small...

The complete plastid genome of S. malacosperma 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 eac...
We determined the complete chloroplast genome of Pedicularis hallaisanensis (Orobanchaceae), a hemi-parasitic perennial herb. This genome is 143,469 bp long and features a large single-copy region (81,664 bp) and a small single-copy region (12,203 bp), separated by two inverted-repeat regions (24,801 bp each). It contains 115 genes – 70 for coding,...
The Annals of the Joseon Dynasty report that large-scale reformations undertaken by Jungjong, 11th king of the Joseon dynasty, were stopped after Kwang-Jo Cho was slandered and subsequently executed. Reportedly, a party opposing the reformations wrote a phrase “走肖爲王” on a leaf in the palace by using sugary water; subsequently, insects ingested the...
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.) as a member of the core genistoids. The recently suggested new circumscription of this tribe involved the removal of traditional members and the...
Astragalus sikokianus has been known as endemic to the Korea-Japan region but is taxonomically confused with A. koraiensis from Korea and A. bhotanensis from Bhutan and western China. To clarify its taxonomic boundary and distribution, we examined external morphological characters and nrITS sequence data. Morphologically, A. koraiensis and A. sikok...
