Aster spathulifolius Maxim. is belongs to the Asteraceae family which is distributed only in Korea and Japan. It is recognize as a traditionally medicinal plants and economically valuable in ornamental field. However, among the Asteraceae family, the Aster genus, which is lacks in genomic resources and information of molecular function. Therefore, we used high throughput RNA-sequencing transcriptome data of the A. spathulifolius to know molecular level function. DeNovo assembly produced 98,660 unigene with N50 value 1126 bp. Unigenes was performed to analyses the functional annotation against NCBI database like plant database of nucleotide (Nt) and non-redundant protein (Nr), Pfam, Uniprot, KEGG and Transcriptional factor (TF). In addition, Distribution of SSR markers also analyzed for future perfectives. Further, Comparing with other two Asteraceae family species like, Karelinia caspica and Chrysanthemum morifolium to the A. spathulifolius shows the number of gene that regulated in internal and external stress respectively salt-tolerant and heat and drought stress to understand the molecular basis related to the different environments stress.

Forty different apartment houses were subjected to assess the status of indoor - landscaping plants found at each apartment house in Seoul for the year of 1986 and 7989. 1. Comparing with those of 1986, 46% increase in total indoor plant species and 68% increase in the number of them were observed. The most abundant sort found in 1786 was oriental orchid, African violet, Scindapsus, cacti, and Clivia, and in 1989, first with oriental orchid, cacti, Chlorophytum, Clivia and Dracaena, in that order. 2. Foliage ornamental plants were mast popularly found in both years of 1986 and 1989 when considered for horticultural classification of plants. 3. Average plant height ranged between 15 to 30 cm in the year of i986, whereas 31 to 80 cm in 1987, indicaling that the size of plants has greatly increased. 4. Kind of planters or containers was most frequently shown to be made of plastic material in both years, and the porcelain ones have significantly been increased to use recently. 5. Most indoor plants placed at the rooms were on the floor in those years, yet the use of planting shelves became particularly manifesting in the year of 1989. 6. Fittonia and cacti were the most frequently used plant materials for installing terrariums at apartment rooms In the year of 1986, whereas Adiantum and Maranta were so in 1989, indicating that the growers choose much adaptable species in apartment environments. Most of the plants grown to landscaping the indoors was apartment verandas in those years. 8. Average number of indoor plants possessed at each apartment houses surveyed for the year of 1986 was 16 different ones, whereas 27 each In 1789, shoving a noteworthy increase in the number. 9. There have been apparent increase and improvement inhabitant's indoor - plant interest in the years to pass and probably to come.

Gwangchiryeong, located adjacent to the Korean DMZ, is a mountain pass connecting Yang-Gu, Gangwon-do with In-je. It reaches a height of 800m (2,624ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304m (4,278ft). It is important to survey the flora of Gwangchiryeong in that not only the area encompassing the waterfall and the valley along with dense old-growth forest has various plant species but also it is a way to make out what kind of plant species exist in the DMZ due to the geographical characteristics of Gwangchiryeong adjacent to the Korean DMZ. Therefore, this study was conducted to elucidate the distribution of vascular plants and their value in Gwangchiryeong. The vascular plants that were collected 9 times from April 2014 to September 2015, and consisted of a total of 513 taxa: 88 families, 297 genera, 441 species, 4 subspecies, 62 varieties and 6 forms. Among those observed species, the rare plant species designated by Korea Forest Service were 22 taxa including Hanabusaya asiatica, Paeonia japonica, Saxifraga octopetala, etc. Endemic species were 22 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica, etc. 18 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 3.5% and 5.6%. Among the surveyed 513 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants were 197 taxa, 154 taxa, 180 taxa, 49 taxa, 24 taxa, 8 taxa, 4 taxa and 3 taxa, respectively.

Proper light intensity, potting media, fertilization level, and shade tolerance were investigated to develop Orostachys (Korean name, Nungyu bawisol) as a potted ornamental plant. The best plant growth was shown at 52% shading. Although plant growth decreased at 82% shading, ornamental value maintained at that shading rate, which indicate that O. 'Nungyu bawisol' has high shading tolerance. At over 90% shading, some of the plants died and showed decolorization and standing erect in leaves, resulting in a big decrease in ornamental value. Potting medium of decomposed granite (DG) : fertilizer-amended media (FAM) : river sand (RS) (6 : 2 : 2, v/v/v) showed the best growth in potted O. 'Nungyu bawisol'. Fresh weight of shoot part was 16 g in DG : FAM : RS (6 : 2 : 2, v/v/v), which was over 2 folds of those at the other medium. Drenching of Hyponex solution diluted by 1,000~2,000 folds 1 time per week brought the highest results in fresh weight, plant width, and runner number. Particularly, fresh weight of shoot part was 13 g higher than that of control (16 g). Leaf color tended to be darkened as concentration of Hyponex solution increased.
