Arthonia ulleungdoensis, a New Lichenized Fungus from Ulleung Island, South Korea.

ABSTRACT: Arthonia ulleungdoensis Lee & Hur is described as a new lichen species from South Korea. The new species is distinguishable from Arthonia ruana A. Massal. by its large, rounded and non-punctiform apothecia, taller apothecial section, asci with fewer spores, and larger and permanently colorless spores. Molecular analyses employing mitochondrial small subunit (mtSSU) and RNA polymerase subunit II (RPB2) sequences strongly support Arthonia ulleungdoensis as a distinct species in the genus Arthonia. Overall, 22 Arthonia species are currently recorded in South Korea. A surrogate key is provided to assist in the identification of all 10 taxa of Arthonia/Arthothelium with muriform spores in Northeast Asia.

Three New Recorded Species of the Physalacriaceae on Ulleung Island, Korea.

Project description:Most known species in the Physalacriaceae are saprotrophs that grow on decaying leaves and wood, and approximately 21 genera in the Physalacriaceae have been reported worldwide. During an ongoing survey of indigenous fungi in Korea, four specimens belonging to the Physalacriaceae were collected on Ulleung Island. These specimens were identified as three species based on morphological characteristics and molecular analysis of rDNA-internal transcribed spacer sequences. Three species in three genera were shown to be new records in Korea: Hymenopellis orientalis, Paraxerula hongoi, and Ponticulomyces orientalis. The latter two are the first records of these genera in Korea. In this study, we provide detailed morphological descriptions of these species and describe their phylogenetic position within the Physalacriaceae.

A new lichenized fungus, Lecanora baekdudaeganensis, from South Korea, with a taxonomic key for Korean Lecanora species.

Project description:Lecanora baekdudaeganensis Lee & Hur is described as a new lichenized fungus from Baekdudaegan Mountains, South Korea. The new species is classified into the Lecanora subfusca group - allophana type and distinguishable from Lecanora imshaugii Brodo by a darker thallus, brownish disc, K-insoluble granules on the surface of the epihymenium, shorter hypothecium, and the presence of oil droplets in the apothecial section. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support Lecanora baekdudaeganensis as a distinct species in the genus Lecanora. A surrogate key is provided to assist in the identification of all 52 taxa in the genus Lecanora of Korea.

The plastome sequence of Ulleung Rowan, Sorbus ulleungensis (Rosaceae), a new endemic species on Ulleung Island, Korea.

Project description:The complete chloroplast genome sequence of Sorbus ulleungensis, a recently described endemic species to Ulleung Island of Korea, was determined. The genome size was 159,632 bp in length with 36.5% GC content. It included a pair of inverted repeats (IRa and IRb) of 26,402 bp, which were separated by small single copy (SSC: 18,824 bp) and large single copy (LSC: 88,003 bp) regions. The cp genome contained 111 genes, including 78 protein coding genes, 29 tRNA genes, and four rRNA genes. Phylogenetic analysis of the combined 78 protein coding genes and four rRNA genes showed that S. ulleungensis was most closely related to Pyrus pyrifolia.

New Species and New Records of Buellia (Lichenized Ascomycetes) from Jeju Province, South Korea.

Project description:A new species and 2 new records of lichen genus Buellia were discovered from Chuja-do Island in Jeju Province during a recent floristic survey: B. chujana X. Y. Wang, S. Y. Kondr., L. Lőkös & J.-S. Hur sp. nov., B. halonia (Ach.) Tuck., and B. mamillana (Tuck.) W. A. Weber. The new species is characterized by a brown, areolate thallus, the presence of perlatolic acid, and a saxicolous habitat. Together with previously recorded species, 10 Buellia species were confirmed from Jeju-do Island. Among these species, 3 growing in the exposed rocky area contained xanthone (yellowish lichen thallus, UV + orange), indicating that production of xanthone in this genus might be a defense strategy against the harm of UV light. Although the genus Buellia has been thoroughly studied in Korea before, novel species have been discovered continuously, and large species diversity has been found in this crustose genus, even from a small rocky island. This study indicates that the coastal area harbors a vast number of crustose lichen species, and there is great potential to discover unknown lichens in the coastal rocky area in Korea.

Penicillium ulleungdoense sp. nov. from Ulleung Island in Korea.

Project description:In a study of the fungal diversity on Ulleung Island in Korea, three novel strains of Penicillium were isolated. Different sites on Ulleung Island were selected for collecting endophytic fungi, and three endophytic fungal strains showed unique morphological characteristics. DNA sequence of the internal transcribed spacer, β-tubulin, calmodulin, and RNA polymerase II second largest subunit regions of the strains were analyzed and they showed unique taxonomic position from the other species of Penicillium section Sclerotiora. The new strains were named Penicillium ulleungdoense sp. nov. As the novel endophytic Penicillium taxa were discovered in a unique environment, the data could be meaningful for understanding the geographical distribution of Ascomycetes on Ulleung Island.

Chloroplast genome of critically endangered Cotoneaster wilsonii (Rosaceae) endemic to Ulleung Island, Korea.

Project description:Cotoneaster wilsonii Nakai is an endangered species endemic to Ulleung Island, Korea. Here we reported the first complete chloroplast gnome sequences of C. wilsonii, which is 159,999 bp in total length with the large single copy (LSC) region of 87,868 bp, the small single copy (SSC) region of 19,335 bp, and two inverted repeat (IR) regions of 26,399 bp. The plastome contains 131 genes, including 84 protein-coding, eight ribosomal RNA, and 37 transfer RNA genes. The overall GC content is 42.6% and those in the LSC, SSC, and IR regions are 34.2, 30.3, and 42.6%, respectively. Phylogenetic analysis of 21 representative plastomes within the family Rosaceae suggests strongly the monophyly of Cotoneaster and C. wilsonii being sister to the clade of Cotoneaster franchetii and Cotoneaster horizontalis.

Development of 26 microsatellite markers in Bupleurum latissimum (Apiaceae), an endangered plant endemic to Ulleung Island, Korea.

Project description:Premise of the studyTo enhance our understanding of evolutionary consequences and to establish a suitable conservation strategy, we isolated microsatellite markers for the endangered Bupleurum latissimum (Apiaceae), which is endemic to the oceanic Ulleung Island. We also attempted cross-amplification in B. euphorbioides and B. longeradiatum to investigate its continental progenitors.Methods and resultsUsing high-throughput sequencing data, we developed 26 polymorphic microsatellite loci in three multiplexes, of which 13 loci were polymorphic in the two related species. For B. latissimum, alleles numbered two to four and the observed and expected heterozygosity ranged from 0.000 to 0.500 and 0.061 to 0.529, respectively.ConclusionsThese developed markers will be useful for understanding evolutionary patterns of B. latissimum in an oceanic island system and for establishing suitable conservation strategies at the genetic level.

Plastome Characterization and Phylogenomics of East Asian Beeches with a Special Emphasis on Fagus multinervis on Ulleung Island, Korea.

Project description:Beech trees of the genus Fagus (Fagaceae) are monoecious and distributed in the Northern Hemisphere. They represent an important component of mixed broad-leaved evergreen-deciduous forests and are an economically important source of timber. Despite their ecological and economical importance, however, little is known regarding the overall plastome evolution among Fagus species in East Asia. In particular, the taxonomic position and status of F. multinervis, a beech species endemic to Ulleung Island of Korea, remains unclear even today. Therefore, in this study, we characterized four newly completed plastomes of East Asian Fagus species (one accession each of F. crenata and F. multinervis and two accessions of F. japonica). Moreover, we performed phylogenomic analyses comparing these four plastomes with F. sylvatica (European beech) plastome. The four plastomes were highly conserved, and their size ranged from 158,163 to 158,348 base pair (bp). The overall GC content was 37.1%, and the sequence similarity ranged from 99.8% to 99.99%. Codon usage patterns were similar among species, and 7 of 77 common protein-coding genes were under positive selection. Furthermore, we identified five highly variable hotspot regions of the Fagus plastomes (ccsA/ndhD, ndhD/psaC, ndhF/rpl32, trnS-GCU/trnG-UCC, and ycf1). Phylogenetic analysis revealed the monophyly of Fagus as well as early divergence of the subgenus Fagus and monophyletic Engleriana. Finally, phylogenetic results supported the taxonomic distinction of F. multinervis from its close relatives F. engleriana and F. japonica. However, the sister species and geographic origin of F. multinervis on Ulleung Island could not be determined.
