Characterization, comparison, and phylogenetic analyses of chloroplast genomes of Euphorbia species.

The genus Euphorbia (Euphorbiaceae) has near-cosmopolitan distribution and serves as a significant resource for both ornamental and medicinal purposes. Despite its economic importance, Euphorbia's taxonomy has long been challenged by the intricate nature of morphological traits exhibiting high levels of convergence. While molecular markers are essential for phylogenetic studies, their availability for Euphorbia has been limited.

Complete plastid genome of Iris orchioides and comparative analysis with 19 Iris plastomes.

Iris is a cosmopolitan genus comprising approximately 280 species distributed throughout the Northern Hemisphere. Although Iris is the most diverse group in the Iridaceae, the number of taxa is debatable owing to various taxonomic issues. Plastid genomes have been widely used for phylogenetic research in plants; however, only limited number of plastid DNA markers are available for phylogenetic study of the Iris.

individuals from Mt. Daeam, once referred to as , exhibit certain morphological characters that are unique within the genus. is one of the most notorious groups for taxonomic problems due to the high morphological variation found in leaf shape, stem numbers, phyllotaxis and seed structure.

Genetic diversity pattern reveals the primary determinant of burcucumber ( L.) invasion in Korea.

Biological invasion is a complex process associated with propagule pressure, dispersal ability, environmental constraints, and human interventions, which leave genetic signatures. The population genetics of an invasive species thus provides invaluable insights into the patterns of invasion. Burcucumber, one of the most detrimental weeds for soybean production in US, has recently colonized Korea and rapidly spread posing a great threat to the natural ecosystem.

Adaptive divergence for a drought resistance related trait among invasive Saltcedar ( L.) populations in southwestern US: Inferences from - .

Biological invasion poses several biotic and abiotic challenges due to abrupt distribution shifts. Invasive species may benefit from local adaptation responding to environmental stresses during colonization. Saltcedar (), a notorious invasive shrub in the western US introduced from Eurasia may have adapted to low rainfall as the species widely occupies the arid land throughout the southwestern US.

The complete chloroplast genome sequences of the (Cucurbitaceae).

(burcucumber) is an annual plant native to the north-eastern America. We investigated the genomic characteristics of the complete chloroplast (CP) genome in with a de novo strategy. The CP genome was 154,986 bp in length including 84 protein coding genes, 37 tRNA genes, and eight rRNA genes.

Genetic Diversity on a Rare Terrestrial Orchid, in South Korea: Implications for Conservation Offered by Genome-Wide Single Nucleotide Polymorphisms.

Monitoring intraspecific diversity offers invaluable insights on conservation practices as the variation is the product of species evolution. Accordingly, the role of population genetic diversity has drawn great attention over the last century responding to the biodiversity loss induced by a series of anthropogenic changes. Orchids are one of the most diverse, yet ironically most rapidly disappearing plant groups due to the specialized habitat preferences.

The complete chloroplast genome sequences of the (Regel) Regel ex Juz. (Rosaceae).

is a deciduous shrub distributed in Central Asia. We determined the genomic characteristics of the complete chloroplast genome in with a de novo assembly strategy. The chloroplast genome was 156,802bp in length harboring 89 protein coding genes, 37 tRNA genes and eight rRNA genes.

Genetic Admixture in the Population of Wild Apple () from the Tien Shan Mountains, Kazakhstan.

There is growing attention given to gene flow between crops and the wild relatives as global landscapes have been rapidly converted into agricultural farm fields over the past century. Crop-to-wild introgression may advance the extinction risks of rare plants through demographic swamping and/or genetic swamping. , the progenitor of the apple, is exclusively distributed along the Tien Shan mountains.

The complete chloroplast genome sequences of the kanitz (Iridaceae).

is a perennial rhizomatous herb distributed in Central Asia. We examined genomic architecture of the complete chloroplast genome in by assembling the Illumina MiSeq reads using de novo strategy. The chloroplast genome is 150,940 bp in length harboring 79 protein-coding genes, 30 tRNA genes, and four rRNA genes.

Complete chloroplast genomes of all six Hosta species occurring in Korea: molecular structures, comparative, and phylogenetic analyses.

Background: The genus Hosta is a group of economically appreciated perennial herbs consisting of approximately 25 species that is endemic to eastern Asia. Due to considerable morphological variability, the genus has been well recognized as a group with taxonomic problems. Chloroplast is a cytoplasmic organelle with its own genome, which is the most commonly used for phylogenetic and genetic diversity analyses for land plants.

An unexpected genetic diversity pattern and a complex demographic history of a rare medicinal herb, Chinese asparagus (Asparagus cochinchinensis) in Korea.

Range-wide population studies of wide spread species are often associated with complex diversity patterns resulting from genetically divergent evolutionary significant units (ESUs). The compound evolutionary history creating such a pattern of diversity can be inferred through molecular analyses. Asparagus cochinchinensis, a medicinally important perennial herb, is in decline due to overharvesting in Korea.

Development and characterization of 30 microsatellite loci for (Berberidaceae).

Premise Of The Study: (Berberidaceae) has been listed as an endangered species in Korea due to extensive collection and destruction of natural habitats. In this study, 30 microsatellite loci, including 25 polymorphic loci, were developed for for use in population-level genetic analyses.

Genetic diversity patterns and domestication origin of soybean.

Genotyping data of a comprehensive Korean soybean collection obtained using a large SNP array were used to clarify global distribution patterns of soybean and address the evolutionary history of soybean. Understanding diversity and evolution of a crop is an essential step to implement a strategy to expand its germplasm base for crop improvement research. Accessions intensively collected from Korea, which is a small but central region in the distribution geography of soybean, were genotyped to provide sufficient data to underpin population genetic questions.

Genetic diagnosis of a rare myrmecochorous species, (Berberidaceae): Historical genetic bottlenecks and strong spatial structures among populations.

Distribution of genetic variation over time and space is relevant to demographic histories and tightly linked to ecological disturbances as well as evolutionary potential of an organism.
