Human-driven habitat fragmentation leads to spatial isolation of endangered plant species increasing extinction risk. Understanding genetic variability and population structure rare isolated is great importance for assessing risk setting up conservation plans. Aconitum austrokoreense, an endemic in Korea, a perennial herb commonly used medicinal purposes. We five nuclear microsatellites one chloroplast marker investigate diversity 479 individuals A. austrokoreense from seven populations...

Understanding the complex influences of landscape and anthropogenic elements that shape population genetic structure invasive species provides insight into patterns colonization spread. The application genomics techniques to these questions may offer detailed, previously undocumented insights factors influencing invasions. We investigated spatial pattern variation on similarity in an riparian shrub, saltcedar (Tamarix L.) by analysing 1,997 genomewide SNP markers for 259 individuals from 25...

Biological invasion consists of spatially and temporally varying stages, accompanied by ecological evolutionary changes. Understanding the genomics underlying dynamics provides critical insights into geographic sources genetic diversity, contributing to successful invasions across space time. Here, we used genomic data model-based approaches characterize

The genus Euphorbia (Euphorbiaceae) has near-cosmopolitan distribution and serves as a significant resource for both ornamental medicinal purposes. Despite its economic importance, Euphorbia's taxonomy long been challenged by the intricate nature of morphological traits exhibiting high levels convergence. While molecular markers are essential phylogenetic studies, their availability limited. To address this gap, we conducted comparative analyses focusing on chloroplast (CP) genomes nine...

Abstract The taxonomy and phylogenetic relationships of related taxa are important for understanding the biology a species. Also, spatial distribution genetic variation may offer insights into history range shifts demographic changes. genus Tamarix L. from Old World is taxonomically challenging group that has widely expanded its in recent past. We examined genomic diversity patterns taxonomic identities Korean species whose remained unresolved. used total 1773 SNP data genotyping by...

Monitoring intraspecific diversity offers invaluable insights on conservation practices as the variation is product of species evolution. Accordingly, role population genetic has drawn great attention over last century responding to biodiversity loss induced by a series anthropogenic changes. Orchids are one most diverse, yet ironically rapidly disappearing plant groups due specialized habitat preferences. Thus, population-level studies may offer powerful tool for orchid programs. Using 3...

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 invasion. Burcucumber, one most detrimental weeds for soybean production in US, has recently colonized Korea rapidly spread posing great threat to natural ecosystem. We aim infer determinants rapid burcucumber by...

Abstract 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 history creating such a pattern can be inferred through molecular analyses. Asparagus cochinchinensis , medicinally important perennial herb, is in decline due to overharvesting Korea. Eight A . populations Korea and three neighboring countries (China, Japan Taiwan) were examined using nine...
