is a non-photosynthetic saprophytic plant of medicinal use in the oriental countries. We report the second complete chloroplast (cp) genome of from a sample collected in Korea. The length of cp genome is only 35,180 bp: there is no inverted repeated region and many photosynthesis genes are missing compared to typical angiosperm cp genomes.

Combined spectroscopic analyses revealed that coumarins - are bis-isoprenylated coumarins with diverse oxidation patterns, while is an enantiomeric di-isoprenylated coumarin. The absolute configurations of the stereogenic centers in the isoprenyl chains were assigned through MTPA and MPA methods, and those of the known compounds triphasiol () and ponciol () were also assigned using similar methods.

The morphological resemblance between A. princeps and A.

Thus, distinguishing the effects of clonal versus sexual individuals in population genetic analyses could provide important insights for evolutionary biology and conservation. To investigate the effects of clonal spread on the fine-scale spatial genetic structure within plant populations, Hosta jonesii (Liliaceae), an endemic species to Korea, was chosen as a study species.

The ndhF sequence from M. latahensis was identical to those of extant M.

To clarify relationships among these early-diverging eudicot lineages, we added entire sequences of 26S rDNA to the existing three-gene data set. In the combined analyses of four genes based on parsimony, ML, and Bayesian analysis, Ranunculales are strongly supported as a clade and are sister to other eudicots.

We investigated the genetic variation in 60 individuals from 12 populations in Korea to elucidate the taxonomic identity of the Korean Adonis complex. Random amplified polymorphic DNA (RAPD) analysis revealed that Korean Adonis comprises three species: A.
View Article and Find Full Text PDFA cDNA clone, designated as Griffithsia japonica cyclophilin-1 (GjCyp-1), was isolated by differential screening of a cDNA library for a red alga, G. japonica. The transcript that corresponded to GjCyp-1 was abundant in vegetative, male, and tetrasporangial thalli, but only the basal level of the transcript was detected in female gametophytes.
