In order to provide fundamental information about the floristic composition of the area along with an assessment of the environmental impact, a floristic study of the vascular plants in the Tamjin River estuary in Gangjin-gun was conducted for a total of nine days, in the period from June 2014 to September 2014. We found that the vascular plants in this region comprised 424 taxa belong to 102 families, 281 genera, 390 species, 5 subspecies, 26 varieties, and 3 forma. Five taxa of Korean endemic plants including Weigela subsessilis (Nakai) L.H.Bailey, Lespedeza maximowiczii var. tricolor (Nakai) Nakai, and Clematis trichotoma Nakai were collected. Two least concern (LC) taxa of rare plants (as designated by the Korea Forest Service) were collected: Hydrocharis dubia (Blume) Backer and Platycladus orientalis (L.) Franco. Ten the floristic regional indicator taxa from the third to the fifth grade were identified: two taxa belonged to grade IV, and eight taxa belonged to grade III. Twenty-four taxa of salt-tolerant plants, including Artemisia fukudo Makino, Carex rugulosa Kuk., and Suaeda glauca (Bunge) Bunge, as well as 44 taxa of aquatic plants, including Najas marina L., Nuphar oguraensis Miki, and Nymphoides indica (L.) Kuntze, were investigated in this region. Fifty-nine taxa of naturalized plants were recorded, among which the following six taxa were plants that caused ecosystem disturbance: Ambrosia artemisiifolia L., Humulus scandens (Lour.) Merr., Lactuca scariola L., Rumex acetosella L., Solidago altissima L., and Symphyotrichum pilosum (Willd.) G.L.Nesom.

Tonggo-san(1066.5m) is located at 36° 53' 00" - 36" 55' 00" in latitude, at 129° 10' 30" - 129° 13' 00" in longitude and on Seo-myeon, Uljin-gun and Subi-myeon, Yeongyang-gun in Gyeongsangbuk-do. Tonggo-san shows the typical vegetation patterns including the middle area of temperate region of Korea represented by the secondary forests of Quercus mongolica and Q. dentata. There was no detailed result on the flora and vegetation of Tonggo-san until now. Therefore, we tried to discuss on the distribution and availability of vascular plants including economical plants. Also, we could discuss the especialized plants and their distributions according to the criteria by the Ministry of Environment. The results of plant collection and their investigation from April in 2001 to November in 2001 are as follows : The vascular plants consist of total 565 taxa; 17 forms, 82 varieties, 466 species, 297 genera, 94 families,37 orders, 4 classes, 2 subphyla. In this area, there were a lot of useful economic plants such as 232 taxa(41%) of edible source, 222 taxa(39％) of forage source, 183 taxa(32%) of medicinal source, and 72 taxa(12%) of ornamental source, 15 taxa(2.6%) timber source, 7 taxa(1.2%) industrial raw material source respectively. Among them, the Korean endemic plants were 22 taxa(3.9％ among total 565 taxa); 1 forms, 2 varieties, 19 species, 22 genera, 16 families. And rare and endangered plants was 1 taxa; Astragatus membranaceus. Also, the naturalized plants were 19 taxa(3.4% among total 565 taxa and 10.4% among the total naturalized plants in Korea).

Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

Supernumerary B chromosomes were found in Lilium amabile (2n = 2x = 24), an endemic Korean lily that grows in the wild throughout the Korean Peninsula. The extra B chromosomes do not affect the host-plant morphology; therefore, whole transcriptome analysis was performed in 0B and 1B plants to identify differentially expressed genes. A total of 154,810 transcripts were obtained from over 10 Gbp data by de novo assembly. By mapping the raw reads to the de novo transcripts, we identified 7,852 differentially expressed genes (log₂FC > |10|), in which 4,059 and 3,794 were up-and down-regulated, respectively, in 1B plants compared to 0B plants. Functional enrichment analysis revealed that various differentially expressed genes were involved in cellular processes including the cell cycle, chromosome breakage and repair, and microtubule formation; all of which may be related to the occurrence and maintenance of B chromosomes. Our data provide insight into transcriptomic changes and evolution of plant B chromosomes and deliver an informative database for future study of B chromosome transcriptomes in the Korean lily.

Taxa of genus Callicarpa in Korea were described taxonomically and studied interspecific relationships, based on the leaf length, leaf width, peduncle length, fruit width and geograhic distribution. Among 12 taxa reported previously in Korea, 3 forms of C. japonica were unifed to original species, C. japonica var. glabra was reserved, Whereas C. shirasawana was not distributed in Korea. As a result, 7 taxa belonging to 3 species, 4 varieties of genus Callicarpa remained. C. japonica complex is considered to be more advanced among the species compared with the bract shapes.

To clarity the species of genus Melandrium (Caryophyllaceae) in Korea, the taxonomic characters were described and interspecific relationships were discussed to the extemal morphology with light and scanning electron microscopy. The position and size of appendages on petal, the shape and venation pattern of leaf, and the external morphology of seed and pollen were approved as the good characters to classify genus Melandrium in Korea. As the result, genus Melandrium in Korea could be arranged as 6 species, 1 variety, 1 forma. M. umbellatum was exclusively distributed in north Korea, and its taxonomic treatment was reserved.

This study was conducted to investigate the vascular plants which can be an indicator of environmental change in Seseok of Jirisan National Park. The purpose of this study was to find out the basic information for the subalpine species. This study showed that the area had a total 295 taxa including 63 families, 177 genus, 252 species, 2 subspecies, 36 variants 5 forms and Pte-Q was 1.7. Among them, Korea endemic plants were 15 taxa such as Abies koreana. Rare plants were 14 taxa such as Viola diamantiaca. Naturalized plants consisted of 5 taxa such as Rumex crispus. The floristic regional indicator plants found in surveyed area were 72 taxa comprising 3 taxa of grade V, 7 taxa of grade IV and 24 taxa of grade III. In summary, The subalpine plants of the survey region consisted of 37 taxa including Abies koreana and Gymnadenia cucullata. As rare plants distributed in subalpine zone respond sensitively to climate change, accuracy distribution range, environmental characteristics of habitat and population dynamics of rare plants should be evaluated quantitatively.
