The choice of molecular markers is the first step when selecting experimental plans in the field of population genetics. The popular molecular markers in population genetic studies are mainly allozyme, RAPD, RFLP, AFLP, microsatellite, SNP and ISSR. Among these, microsatellites are frequently found in nuclear, chloroplast and mitochondrial genome, showing a high level of polymorphism and nuclear microsatellites are codominant. Thus, it is a favorable molecular marker for population structure analyses and genetic diversity studies. Microsatellites are composed of tandem repeated 1~6 base pair nucleotide motifs and can be easily amplified by PCR reactions using locus specific primers. Because microsatellites have low cross-species transferability, however, they are only applicable between phylogenetically close species. In wild plants, the lack of genomic information and the high development cost of the microsatellite obstruct the wider use of microsatellites in plant population genetics research. In this review, we introduce the basis for microsatellite markers, the development process, and analytical methods as well as evolutionary models and their applications. In addition, possible genotyping errors which lead to erroneous conclusions are discussed.

To elucidate the taxonomic status of the genus Megaleranthis Ohwi, a monotype in Korea, its distribution and morphological characteristics were studied and a cluster analysis was performed. The cluster analysis showed that Megaleranthis was separately clustered from Trollius and Calathodes. Megaleranthis is morphologically different from Calathodes Hook.f. et Thomson in having petals, and from Trollius L. in having an involucre instead of a caulescent leaf under the flower and follicles with simple veins. The three genera above are distributed independently within Asia, although they can be found together at the boundaries where their distributions overlap: Trollius and Calathodes occur together between the Sichuan and Yunnan provinces in China, and Megaleranthis and Trollius can both be found on the northern edge of the Korean Peninsula. From both a morphological and a distributional viewpoint, Megaleranthis should be recognized as an independent genus different from both Trollius and Calathodes.

The purpose of this study was to analyze the interspecific relationships of Chenopodium album and its related taxa collected in Korea. The 18S-26S ribosomal DNA (45S rDNA) loci were detected directly on mitotic chromosomes by fluorescence in situ hybridization (FISH) and the chromosome numbers were examined using aceto-orcein methods. The chromosomal numbers of Chenopodium album var. album and C. album var. centrorubrum were 2n = 6x = 54, whereas for C. album var. stenophyllum, this number was 2n = 4x = 36. The basic chromosome number was x = 9. The biotin labeled 18S-26S rDNA probe exhibited eight yellow fluorescent signals on the metaphase chromosome of C. album var. album and var. centrorubrum respectively, while two yellow signals of C. album var. stenophyllum were noted. All of the signals on the chromosomes were located at the terminal regions. The chromosome number and FISH findings suggest that C. album var. centrorubrum is merged into var. album and that it is clearly distinguished from C. album var. stenophyllum.

The Acer wilsonii complex including A. wilsonii, A. tutcheri, and A. confertifoilum is distributed in southern China. Morphological variation was examined to delimit the species and to determine whether recognition at the specific level was warranted. Univariate and bivariate statistical methods, based on data taken from herbarium specimens, were used to examine morphological variation between and within species. This study showed that A. tutcheri differed from A. wilsonii by its rather short inflorescence, small leaf blades, and three leaf lobes with distinctive serrate leaf lobes. In contrast, there was virtually no separation of taxa with respect to the paniculatecorymbose or short paniculate inflorescence between A. confertifolium and A. tutcheri, suggesting that A. confertifolium morphologically resembled A. tutcheri and is a rather smaller form of it. Circumscription of Acer wilsonii has been quite troublesome, because the important holotype and isotype specimens contained different species under the same number and were misleading with respect to the correct application of the name. Furthermore, lobation is very weak within ser. Sinensia, but diversified inflorescences usually occur in China. A three lobed leaves species, A. wilsonii, represents the reduction in lobation without any modification of panicle inflorescences and seems to be closely related to A. sinense. However, A. tutcheri, which shows a reduction in panicle inflorescence with four petals and sepals, may not be closely related to A. sinense. Three lobed taxa may not correctly reflect the true relationship within ser. Sinensia. The designated lectotype of A. wilsonii, line drawings of representative leaves of related species, a key, and distribution maps of these taxa are presented.
Molecular Phylogenetic Studies of Korean Calystegia R.Br. Based on ITS and psbA-trnH Sequences

Korean Journal of Plant Taxonomy, volume 41, issue 4, 2011, Pages 338~344
Molecular phylogenetic studies were conducted to evaluate evolutionary trends, relationships and species identities among four species, one variety and one outgroup of the Korean Genus Calystegia. The important characteristics of Calystegia are the shape of the lamina, the length ofthe corolla and the presence of hair. However, many variations were observed as regards the characteristics of the leaf, making true identification difficult. In molecular phylogenetic studies, C. soldanella formed one clade, and it was located mostly in the base. C. hederacea and C. sepium did not form an independent clade in their ITS regions and psbA-trnH regions, and this investigation could not confirm a relationship. Therefore, a relationship between these two species is not sufficiently supported by these markers (ITS and psbA-trnH). Consequently, this research should be achieved through many samples and markers. C. sepium var. japonica and C. dahurica are closely related.

The morphological characters of Scrophularia kakudensis Franch. and its relatives were examined. The major features of S. kakudensis were determined to resolve the taxonomic confusion with the closely related taxa of S. kakudensis var. microphylla, S. pilosa and S. cephalantha. S. kakudensis is characterized by its flowering in Jul. to Sep., the node numbers on a stem, the size of the leaves, the development of inflorescences and the presence of glandular trichomes on its stems and leaves. S. cephalantha is distinct from S. kakudensis by the earlier flowering season, fewer node numbers on a stem, and fewer numbers of flowers on shorter rachis. Smaller sizes of S. kakudensis var. microphylla, considered to be a problematic character previously, are stable and distinctive from other taxa in the natural habitats of the multiple populations investigated in the study. Therefore, the taxon should remain as a variety of S. kakudensis. An examination of the diagnostic characteristics of S. pilosa, such as its inflorescence type and the presence of a stem with pubescence, does not provide sufficient distinction from S. kakudensis. A type specimen and habitat survey also support the merging of the two taxa. S. pilosa should be treated as a synonym of S. kakudensis, because it is considered to be a misidentification of S. kakudensis.
Phylogeny of the Polygonatum odoratum Complex Inferred from Multiple cpDNA and Nuclear RNApol2_i23 Sequence Data (Ruscaceae)

The sequence data of the plastid DNA (trnL-F IGS, trnL intron, and trnH-psbA) and nuclear DNA (RNApol2_i23) markers were utilized to study phylogenetic relationships among the taxa in the Polygonatum odoratum complex (Ruscaceae). European P. odoratum individuals form a clade with a high bootstrap value, which is a sister to the clade of Korean P. odoratum var. odoratum, P. odoratum var. pluriflorum and P. robustum. The formation of the clade with P. odoratum var. odoratum, P. robustum, and one accession of P. odoratum var. pluriflorum indicates geological speciation in isolated populations in the islands following dispersal events from the mainlands. All data sets form two major clades, which are congruent with the subgroups divided by the basic chromosome numbers (x = 9 and x = 10). Although it is not easy to test the hypothesis of the decrease in the basic chromosome number due to scatter taxon sampling in this study, the molecular data strongly suggested that aneuploidy plays an important role in lineage diversification in the genus Polygonatum. The cytological data was not strongly supported by the cpDNA sequences. Further investigations of the cytological, morphological, and geographical characteristics with comprehensive sampling are desired to understand the evolution and lineage diversification in the genus.

Korean Journal of Plant Taxonomy, volume 41, issue 4, 2011, Pages 361~364
We report an unrecorded plant species, Elatostema laetevirens Makino (Urticaceae), in Korea. This species was collected for the first time from under the canopy of an evergreen forest in Hyodoncheon, Sanghyo- dong, Soeguipo-si and Tamra valley in Ohdeung-dong, Cheju-si of the Province of Cheju in Korea. E. laetevirens Makino was quite distinct from others of the genus Elatostema in Korea owing to its perennial nature, the absence of trichomes in the stem and the absence of peduncles during the inflorescence period. This species was given the Korean name 'pu-reun-mong-ul-pul' based on the absence of luster and the bluish green color on the adaxial surface of its leaves.
A New Hybrid Species of Pulsatilla (Ranunculaceae): P. x yanbianensis H.Z. Lv
Lv, Hui-Zi ; So, Soon-Ku ; Kim, Mu-Yeol ;
Korean Journal of Plant Taxonomy, volume 41, issue 4, 2011, Pages 365~369
In this paper, a new hybrid species, Pulsatilla x yanbianensis H.Z. Lv, is named and described from the Yanbian area of Jilin Province in China. Molecular data confirm that this taxon is a result of natural hybridization between P. dahurica and P. cernua. As intermediate and mosaic phenotypes are expected for an interspecific hybrid, the leaves of P. x yanbianensis are fully expanded at the anthesis, resembling one of the parental species, P. daurica. However, the hybrid taxon is distinct from P. daurica by having reddish violet sepals and sterile fruits. Pulsatilla x yanbianensis also resembles the other parental species, P. cernua, in that it has dark red sepals and styles. The new hybrid, however, can be distinguished from P. cernua because it has leaf margins with short hairs and fully expanded leaves at the anthesis.

We investigated the area around four moors from May 2009 to June 2010 for plant diversity in Moojechineup, officially designated as the Ramsar wetland. The vascular plants of Moojechineup at Mt. Jeongjok were recorded as total 149 taxa, 55 families, 105 genera, 128 species, 1 subspecies, 16 varieties, and 4 forms. Rare plants were observed 7 taxa (Eriophorum gracile Koch, Drosera rotundifolia L., Iris ensata var. spontanea (Makino) Nakai, Kobresia bellardii (All.) Degl, Utricularia bifida L., Utricularia racemosa Wall., Utricularia yakusimensis Masam.). Korean endemic plants were 1 taxon, floristics special plants were 19 taxa, and naturalized plants were 3 taxa. Phytogeographical and evolutionarily, Eriophorum gracile is an important species; hence, further studies are needed to conserve it. Moojechineup is similar to the Shinbulsan wetland in terms of wetland plants (hydrophytes). Moojechineup's flora changes are in process slowly compared to earlier work; thus, continuing interest and appropriate measures should be encouraged.

Korean Journal of Plant Taxonomy, volume 41, issue 4, 2011, Pages 383~397
This study was carried out to investigate the flora of the southeastern areas, including Donghae-si and Samcheok-si, of Gangwon-do. Vascular plants based on voucher specimens were summarized as 750 taxa, including 109 families, 394 genera, 642 species, 5 subspecies, 90 varieties, and 13 forms. Among the investigated 750 taxa, 17 Korean endemic, 38 rare plants and 147 specially designated plants by the Ministry of the Environment were also included. The naturalized plants were 28 taxa, and the percent of naturalized plant species was estimated as 3.7%. The life form of the investigated taxa was the H-R5-D4-e type. The usefulness of the plants of the 750 taxa listed consists of 284 taxa (37.9%) of edible plants, 232 taxa (30.9%) of medicinal plants, 124 taxa (16.5%) of pasture plants, 88 taxa (11.7%) of ornamental plants, 21 taxa (2.8%) of timber plants, 20 taxa (2.7%) of fiber plants, 7 taxa (0.9%) of miscellaneous plants and 3 taxa (0.4%) of industrial plants.

The flora in the region of Mt. Sobaeksan National Park (N
43') was surveyed from April of 2005 to October of 2011. The vascular plants from 27 field surveys were revealed to total 869 taxa, comprising 112 families, 429 genera, 756 species, four subspecies, 91 varieties and 18 forms. Sixty-eight taxa were the first records from this region. This field study discovered significant plants in various categories. Korean endemic plants numbered 25 taxa, and 18 taxa designated by the Korean Forest Service as rare plants were investigated in this region. The taxa in category II of rare and endangered plants and higher than the third degree among the floristic regional indicator plants designated by the Korean Ministry of the Environment were three taxa and 75 taxa, respectively. From a geographical perspective, limited distribution of Saxifraga octopetala, Corydalis grandicalyx, Aegopodium alpestre, and Polygonatum acuminatifolium at a latitude higher than that of Sobaeksan National Park suggest that Sobaeksan National Park might be the limit line of the distribution of the taxa. Stewartia koreana demonstrate a reversed pattern from the taxa above, occurring at a latitude lower than that of Sobaeksan National Park. In addition, naturalized plants of 53 taxa were recorded.

The vascular flora in the Mt. Cheongtae area, located Pyeongchang-gun in Gangwon-do, were surveyed 14 times from April of 2008 to October of 2011. The result of this survey revealed 663 taxa in total, comprising 89 families, 342 genera, 577 species, 6 subspecies, 73 varieties and 7 forms. In the flora of this area, 19 taxa were Korean endemic plants and 24 taxa were rare and endangered plants of Korea. The floristic regional indicator plants found in this area were 136 taxa comprising 4 taxa of grade V, 16 taxa of grade IV, 31 taxa of grade III, 41 taxa of grade II and 44 taxa of grade I. Naturalized plants in Korea numbered37 taxa. In addition, 485 taxa were categorized by usage into 8 groups, as follows: 240 edible, 8 fiber, 177 medical, 60 ornamental, 245 pasturing, 2 industrial, 12 dyeing and 16 timer plants.

We investigated the flora of Imja-do(Isl.), an island of the Shinan archipelago, located in Imja-myeon, Shinan-gun, Jollanamo-do and discussed the vascular plants found there. Twenty-four separate field trips (100days) were completed from August of 1997 to October of 2009. As a result, we identified the distribution of 526 taxa in Imja-do(Isl.), comprising 112 families, 331 genera, 463 species, 1 subspecies, 60 varieties, and 2 forms. There are a total of 78 taxa of floristic regional indicator plants and one taxon of level II endangered species, Millettia japonica, as designated by the Korean Ministry of the Environment. The floristic regional indicator plants are as follows; four taxa of level V such as Utricularia bifida, two taxa of level IV such as Cladium chinense, 14 taxa of level III such as Aletris spicata, three taxa of level II, and 55 taxa of level I. In addition, one endangered species (EN), Nymphoides coreana, five vulnerable species (VU),such as Ilex cornuta, and three near-threatened species (NT) such as Utricula riaracemosa, were found in the investigated area. The plants of Imja-do(Isl.) are classified into four types based on the plant geographical origin, as follows: 1) boreal plants advancing southward in a glacial period, 2) temperate plants spreading eastward from the Himalayas and China to Japan passing through the south coast of Korea, 3) subtropical plants, and 4) indigenously developed endemic species of the warm-temperate region of East Asia.
