In this study, we used DNA barcoding for the accurate identification of Korean Caryophyllaceae. A total of 78 taxa ( = 215) were sequenced based on three chloroplast regions (L, K, and A-H) and nuclear ribosomal internal transcribed spacers (ITS).

Our objective was to compare heterogeneity index (HI) between fetal lung images captured in grayscale and those same images after conversion to Ice and Sepia. Fetal lung images were obtained during medically indicated ultrasound examinations.

View Article and Find Full Text PDFThe genus (Agavoideae and Asparagaceae) is one of the most popular landscaping and ornamental plants native to temperate East Asia. Their popularity has led to extensive hybridization to develop various cultivars. However, their long history of hybridization, cultivation, and selection has brought about taxonomic confusion in the species delimitation along with their indistinguishable morphology.

The confound-minimized cross-task design has been widely used to examine the characteristics of top-down cognitive control underlying the congruency sequence effect (CSE) without feature integration and contingency learning confounds. The present study reanalyzed our previous data obtained with the confound-minimized cross-task design, this time including the preceding congruency repetition type, to examine whether the cross-task CSE is confounded by feature integration from two-back (n-2) trials or multiple expectancies regarding the congruency and the congruency repetition type of the upcoming trial. As a result, the cross-task CSE interacted with the arbitrariness of S-R mapping or response mode regardless of the preceding congruency repetition type, indicating the contribution of top-down control triggered by conflict.
View Article and Find Full Text PDFThe present study investigated how response mode determines the specificity of control responsible for the congruency sequence effect (CSE), especially when conflict arises from spatial dimensions. Horizontal and vertical Simon tasks were presented in turn, while response mode (Experiment 1) or task-relevant stimulus dimension (Experiment 2) was manipulated. All responses were made by aimed movements to make the relative salience of the horizontal and vertical dimensions equivalent regardless of response mode.

The identification of taxa, however, has been hampered by insufficient diagnostic morphological characteristics and frequent natural hybridization. Development of novel DNA markers or barcodes with sufficient resolution to resolve taxonomic issues of Artemisia in East Asia is significant challenge.

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.

is a medicinal plant belonging to the family Aristolichiaceae. In this study, complete chloroplast (cp) genome sequence of was characterized through assembly with next-generation sequencing data. The cp genome is 160,182 bp long and has a typical quadripartite organization consisting of a large single-copy (LSC), a small single-copy (SSC), and a pair of inverted repeats (IRs).

Previous results regarding what consecutive tasks must have in common to engender the cross-task CSE are inconsistent. The present study examined the roles of stimulus-response (S-R) mappings and response mode as critical factors in determining the scope of control.
