The transcriptomes of four ginseng accessions such as Cheonryang (Korean ginseng cultivar), Yunpoong (Korean ginseng cultivar), G03080 (breeding line of Korean ginseng), and P. quinquefolius (American ginseng) was characterized. As a result of sequencing, total lengths of the reads in each sample were 156.42 Mb (Cheonryang cultivar), 161.95 Mb (Yunpoong cultivar), 165.07 Mb (G03080 breeding line), and 166.48 Mb (P. quinquefolius). Using a BLAST search against the Phytozome databases with an arbitrary expectation value of 1E-10, over 20,000 unigenes were functionally annotated and classified using DAVID software, and were found in response to external stress in the G03080 breeding line, as well as in the Cheonryang cultivar, which was associated with the ion binding term. Finally, unigenes related to transmembrane transporter activity were observed in Cheonryang and P. quinquefolius, which involves controlling osmotic pressure and turgor pressure within the cell. The expression patterns were analyzed to identify dehydrin family genes that were abundantly detected in the Cheonryang cultivar and the G03080 breeding line. In addition, the Yunpoong cultivar and P. quinquefolius accession had higher expression of heat shock proteins expressed in Ricinus communis. These results will be a valuable resource for understanding the structure and function of the ginseng transcriptomes.

Korean ginseng (P. ginseng C. A. Meyer) is one of the most important medicinal plant in the world. Understanding genetic variability among the assortment of Korean ginseng is important for breeding. The aim of this study was to molecularly characterize Korean ginseng cultivar and breeding lines through the use of eight previously reported STS markers (MFGp183, MFGp130, MFGp110, UFGp74, UFGp163, MFGp108, MFGp81 and UFGp156). All STS markers produced interpretable electropherograms from 31 accessions consisting of 11 Korean ginseng cultivars and 20 breeding lines. When eight STS markers were combined, we identified to total 19 genetic patterns; in particular, nine cultivars (Chunpoong, Yunpoong, Gopoong, Gumpoong, Sunpoong, Sunone, Cheongseon, Sunhyang, Cheonryang) and 5 breeding lines (G08012, G04079, G04075, G08036, G04110) in ginseng samples can be discriminated from the others. Together with other available markers, these STS markers will contribute to the management of ginseng genetic resources and the protection of breeders' rights.

This study was carried out to investigate the cause of leaf discoloration occurring frequently in paddy cultivation. Chemical property of soil and inorganic nutrient component of leaf were analyzed on abnormal fields of 7 regions where leaf discoloration occurred severely and normal fields of 7 regions among ginseng garden. The pH of abnormal fields was strong acidic condition (pH 5.51) compare to normal fields of slightly acid condition (pH 6.42). Calcium and magnesium content in abnormal fields were lower distinctly than that of normal fields, while EC, organic matter, phosphate, and potassium content showed not distinct difference between abnormal and normal fields. Whereas calcium and magnesium content were distinctly high in normal fields, both of potassium and iron content of ginseng leaf were distinctly high in abnormal fields. In particular, iron content of abnormal fields was more 1.94 times in soil, and 3.03 times in leaf than that of normal fields. In soil chemical property, there were significant negative correlation between leaf discoloration ratio and soil pH, and there were also significant positive correlation between leaf discoloration ratio and iron content. In ginseng leaf, there were highly significant negative correlation between leaf discoloration ratio and calcium content, and there were also highly significant positive correlation between leaf discoloration ratio and iron content.

This study was carried out to select optimal shade materials among four-layered polyethylene (PE) net (FLPN), aluminium-coated PE sheet (APSS), and blue PE sheet (BPSS) in condition of paddy field cultivated 6-year-old ginseng. The order of light-penetrated ratio and air temperature by shade materials was BPSS 〉 APSS 〉 FLPN. Light-penetrated ratio of BPSS before two fold shade was more 3 times and 2 times than that of FLPN and APSS, respectively. Air temperature of BPSS was also higher 1.6℃ and 1.4℃ than that of FLPN and APSS, respectively. BPSS showed good cultural environment because all of light-penetrated ratio and air temperature were become higher in spring and fall season but lower in summer season by additional shade with two-layered PE net. Survived-leaf ratio was highest in BPSS and lowest in FLPN causing a little water leak on a rainy day. Rusty-root ratio was also highest in FLPN because soil moisture content was increased by water leak. The order of root yield was BPSS 〉 APSS 〉 FLPN, and the cause of highest yield in BPSS was higher light-penetrated ratio during spring and fall season, higher survived-leaf ratio, and lower rusty-root ratio than that of APSS and FLPN. BPSS showed highest total ginsenoside content because of high light-penetrated ratio, blue light effect, and the difference in dry matter partitioning ratio such as low taproot ratio, and high lateral root ratio.

FRP has higher design tensile strength than steel bar and outstanding characteristics such as light-weight, non-corrosion, and lower conductivity. And, current researchers evaluated flexural performances of flexural members using FRP and suggested the development length and splice length by using bonding failure test. This Researchers has the main purpose to examine the quality of bonding failure in the lap spliced FRP and deformed bar. Variables in this test with total 208 specimens planned are re-bar location, embedment length, covering depth, re-bar diameter. And, this study describes the result of our review on the bonding strength of the lap-spliced FRP and the deformed bar located at the bottom.
