Wangsania, a new genus of Apiaceae from limestone areas and typified by W. insolens (Kitagawa) B.Y. Lee & J.O. Hyun, is described from Gangwon-do, Korea. Wangsania insolens was initially treated as Peucedanum insolens Kitagawa due to similarity with Peucedaunm cervaria, but it differs markedly in its unique morphological characters, such as rarely branched roots and a single basal leaf with 3 or -4 ternately dissected leaflets. These characters apparently represent apomorphies for Wangsania. The parsimony analysis of nuclaer ribosomal DNA ITS sequences revealed Wangsania to be not closely related to either Peucedanum or to any of 14 different tribes or clades within subfamily Apioideae.

The Apiaceae genus Daucus consists of approximately 25 species (including carrots) which are characterized by the presence of bracts in pedunculate umbels, dorsally compressed mericarps, hairs on primary ridges, and uniseriately arranged spines on the secondary ridges of the fruit. Taxonomically, Daucus has been considered to be one of the most problematic genera in the Apiaceae due to the highly variable fruit morphology. Despite taxonomic controversy and economic importance of the genus, no rigorously constructed estimate of phylogenetic relationships exists. To examine generic limit and relationships among species of Daucus and its putatively related taxa, phylogenetic analyses of characters derived from nuclear ribosomal DNA ITS sequences were conducted. Two major clades emerged within Daucus, but neither of them have been previously recognized using morphological characters. The phylogeny also provides taxonomic status of recently reported new species of Daucus, D. arcanus and D. conchitae.

As part of a larger study with the aim to discover indigenous prokaryotic species in Korea, nine bacterial strains were isolated and assigned to the phylum Proteobacteria in 2016. High 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clades with known species indicated that each strain belongs to an independent and predefined bacterial species. This is the first report of these nine species in Korea: two strains of the Methylobacterium, two strains of the Microvirga, one strain of the Pantoea, and four strains of the Psychrobacter, all within the Proteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

The reexamination of the fungal genus Botryosphaeria on 12 plant species of 10 families was carried out based on molecular phylogenetic analyses using the regions of translation elongation factor 1-α, β-tubulin, DNA-directed RNA polymerase II subunit, and internal transcribed spacer region of rDNA and morphological characteristics. Japanese isolates were divided into five clades and include Botryosphaeria dothidea, B. qingyuanensis, B. sinensis, and Botryosphaeria spp. Two species, B. qingyuanensis and B. sinensis have been newly added to the Japanese mycoflora, but their host plants are not specified. Botryosphaeria tenuispora isolated from Leucothoe fontanesiana and insect galls on fruits of Aucuba japonica has been proposed as a new species.

The chloroplast genome of Glycyrrhiza uralensis Fisch was sequenced to investigate intraspecific variations on the chloroplast genome. Its length is 127,689 bp long (34.3% GC ratio) with atypical structure of chloroplast genome, which is congruent to those of Glycyrrhiza genus. It includes 110 genes (76 protein-coding genes, four rRNAs, and 30 tRNAs). Intronic region of ndhA presented the highest nucleotide diversity based on the six G. uralenesis chloroplast genomes. A total of 150 single nucleotide polymorphisms and 10 insertion and deletion (INDEL) regions were identified from the six G. uralensis chloroplast genomes. Phylogenetic trees show that the six chloroplast genomes of G. uralensis formed the two clades, requiring additional studies to understand it.

Elsinoë are plant pathogenic fungi that cause scabs, spotted anthracnose, and some morphological distortions on various plants, including woody plants, economically important crops, and ornamental plants. Taxonomical reexamination of Elsinoë species in Japan has not yet been conducted based on the modern species criteria. In this study, several Japanese isolates were reexamine based on the morphological and molecular-phylogenetic analysis of the internal transcribed spacer region (ITS), large subunit gene (LSU)m and protein-coding gene such as RNA polymerase II subunit (rpb2) and Translation elongation factor 1-alpha (tef). Japanese isolates were divided into four clades and three new species, Elsinoë hydrangeae, E. sumire, and E. tanashiensis were proposed. One species, Sphaceloma akebiae, was transferred to the genus Elsinoë.

Lecanora is one of the largest genera of lichens worldwide. These lichens can be easily seen, and are commonly found on trees and rocks. Most Korean Lecanora species belong to the Lecanora subfusca group, which has well-defined superficial thallus, red-brown apothecia, and soredia. The new species of L. neobarkmaniana grows on rocks, farinose soredia coalescing, usually covering the whole thallus, and containing atranorin and zeorin. We used internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequence data to identify the phylogenetic relationship across Lecanora sequence data and found the species to form different clades. In this study, we reported some interesting findings and described the genetic relationship with other sorediate Lecanora species and the characteristics of the new species. An identification key for the Korean sorediate Lecanora species is given.

The mitochondrial cytochrome b gene of the Korean subspecies (Falco tinnunculus interstinctus) of the common kestrel has been analyzed. According to the molecular phylogeny of six subspecies of common kestrel, six subspecies of the common kestrel were divided into two clades: the first clade is composed of the South African subspecies (F. t. rupicolus) and the second clade includes 5 subspecies (F. t. tinnunculus, F. t. rufescens, F. t. interstinctus, F. t. canariensis and F. t. dacotiae) of the common kestrel. Korean subspecies, F. t. interstinctus was closely related to F. t. rufescens and original subspecies F. t. tinnunculus.

In 2022, research for native prokaryotic species in Korea reported 10 unrecorded bacterial strains affiliated to phyla Actinomycetota, Bacillota, and Pseudomonadota. The strains formed monophyletic clades with the most closely related species (with ≥98.7% sequence similarity) in the 16S rRNA gene sequencing. Among them, four species of the phylum Actinomycetota, two species of the phylum Bacillota, and four species of the phylum Pseudomonadota have not been reported in Korea, suggesting unrecorded species in Korea. Information on strains such as Gram staining reaction, colony and cell morphology, biochemical characteristics, and isolation sources were provided in the species description.

High temperature is one of major environmental stress. Heat tolerance managing is difficult through the phenotypic selection, so marker assistant selection (MAS) using molecular markers like as RAPD, SSR etc. was tried to select useful traits for heat tolerance. Fourteen SSR markers reported by previous research were selected for this research. We tried to evaluate 14 SSR markers for MAS using 31 useful wheat resources including 24 crossing line from Turkey, six Korean wheat cultivars and Chinese spring. The average of the number of alleles and PIC values in this study were 6.14 and 0.64, respectively. Two major clades and four sub clades were grouped by phylogenetic tree using UPGMA. Four Korean wheat cultivars were distinct from other Turkey resources in the phylogenetic dendrogram. From the results, we expected that these markers were able to adapt to screening wheat genotyping for heat tolerance.
