The first comprehensive cladistic analysis of Miridae, the plant bugs, based on ~3000 base pairs of mitochondrial (COI, 16S) and nuclear (18S, 28SD3) genes, is presented. For 105 taxa (101 Mirid species in 7 subfamilies and 11 tribes, and 4 outgroups) in 7 subfamilies and 11 tribes of Miridae, the combined dataset was analyzed using ML (maximum likelihood), BC (bayesian criteria) and MP (maximum parsimony). Clades recovered in all analyses, comprise 6 main groups: Cimicomorpha and Miridae; Phylinae; Mirinae (Eurystylus + Polymerus + Proboscidocoris + Taylorilygus + Stenodemini); Orthotylinae; Mirini (Adelphocoris group except “Apolygus complex”); Apolygus complex; Deraecorinae; Bryocorinae + Isometopinae + Cylapinae. Our results indicate 1) the monophyletic relationships of two subfamilies Phylinae and Deraeocorinae within the family Miridae; 2) the paraphyly of subfamily Mirinae. Phylogenetic relationships at the tribal or subfamily level are provided in comparison with the prior studies based on morphological data.

The flower bugs (Heteroptera: Anthocoridae) is usually known as biological control agents against various kinds of agricultural pests such as aphids, mites, thrips and so on. Since the classification of the family Anthocoridae has been controversial, the molecular phylogenetic study was conducted with 44 species including 6 outgroup taxa. Three genes, a total of 3277 bp of sequence data (nuclear 18S rDNA: 2022bp, 28S rDNA: 755bp, and mitochondrial 16S rDNA: 498bp), were analyzed using ML (maximum likelihood) and Bayesian methods, excluding MP (maximum parsimony) as the incongruence length difference (ILD) test has very low (0.001) P-values on all partition tests. Our results support the rank and monophyly of the family Lasiochilidae which was exclusively separated from the main clade of Anthocoridae proposed by Schuh and Stys (1991), and indicate the monophyletic relationships among tribes and genera within the family Anthocoridae. According to our results, the genus Amphiareus should be out of the tribe Dufourini and treated as the tribe level and The three genera, Blaptostethus, Scoloposcelis and Xylocoris should be placed to the family Lyctocoridae. We also propose the evolutionary theory of Anthocoridae based on their habitats, hunting behavior and the molecular phylogenetic results.

About 10 percent of quasars are known to exhibit deep broad absorption troughs blueward of prominent permitted emission lines, which are usually attributed to the existence of outflows slightly above he accretion disk around the supermassive black hole. Typical widths up to 0.2c of these absorption roughs indicate the velocity scales in which special relativistic effects may not be negligible. Under he assumption of the ubiquity of the broad absorption line region in quasars, the broad emission line flux will exhibit Thomson scattered components from these fast outflows. In this paper, we provide our Monte Carlo calculation of linear polarization of singly Thomson scattered line radiation with the careful considerations of special relativistic effects. The scattering region is approximated by a collection of rings that are moving outward with speeds υ =cβ < 0.2c near the equatorial plane, and the scattered line photons are collected according to its direction and wavelength in the observer's rest frame. We find that the significantly extended red tail appears in the scattered radiation. We also find that the linear degree of polarization of singly Thomson scattered line radiation is wavelength-dependent and hat there are significant differences in the linear degree of polarization from that computed from classical physics in the far red tail. We propose that the semi-forbidden broad emission line C III]1909 may be significantly contributed from Thomson scattering because this line has small resonance scattering optical depth in the broad absorption line region, which leads to distinct and significant polarized flux in this broad emission line.

매미나방알좀벌, Ooencyrtus kuvanae (Hymenoptera : Encyrtidae), 이 기주를 발견한 후 산란을 끝내고 기주를 떠날 때까지 11단계의 연속행동과정, 그리고 자기몸청소, 휴식 등과 같은 부수적인 행동이나 산란관에 의한 상처로부터 나오는 기주체액을 먹는 습성 등이 조사되었다. 기생벌에 기주난이 연속적으로 주어졌을 때는 처음 산란을 마친 매미나방알좀벌은 활발히 주변을 움직이며 다음 산란대상이 되는 기주에 보다 빨리 접근하는 경향을 나타내고, 또한 기주접촉단계에 소요하는 시간이 첫 번째 난에서 보다 두 번째 세 번째난에서 단축되는 경향을 나타내는 것으로 관찰되어 산란경험이 기주발견과 인식에 중요한 영향을 미치는 것으로 조사되었다.

Background : Licorice has been used as a source of medicine and a food material in East-Asia. Recently, demand for licorice increased in market due to a growing interest in health. Thus we conducted breeding research to solve the problems associated with domestically cultivated licorice such as low productivity and low glycyrrhizin content. Methods and Results : We crossed European licorice (G. glabra L.; female parent) and Chinese licorice (G. uralensis Fisch; male parent) in the greenhouse in May 2007. In September 2007, crossed and germinated seeds were retrieved and sown in the greenhouse. In June 2008, stolons were separated from the F1 licorice seedlings and cultivated, resulting in 32 clonal lines of interspecific hybrids. Among them we selected good lines and then conducted the replicated yield trials (RYT) in 2012-2013 and local adaptability test (LAT) in 2014-2015. The results, GLYES9 showed that was elect of stem, oblong of leaf shape, red-brown of root color. Glycyrrhizin conten of GLYES9 (3.0%) was higher than G. uralensis (1.9%) at four regions from 2014 to 2015. GLYES9 was less than 10% in the desease of brown spot (G. uralensis was more than 30%). The root yield of GLYES9 was 4.31 ton per hectare, which was increased 193% compared with a check variety of G. uralensis. Therfore, we named GLYES9 as new cultivar ‘Dagam’. Conclusion : Depending on the above results, we have developed a new licorice cultivar ‘Dagam’ by the medicinal crop breeding team of National Institute of Horticulture and Herbal Science, RDA, in 2015. It showed brown spot disease resistant, high-glycyrrhizn content and high-yielding than colleted Glycyrrhiza spp.

Background : Cucuma longa L., in the family Zingiberaceae, is distributed in tropical and/or sub-tropical regions mainly in India and China. This species is commonly called tumeric, powder is used as medicinal herbs and/or flavor enhancer. It has been cultivated in southern region mainly Jindo. However, it might be possible to extend cultivation region due to rise in average temperature. In order to select superior lines, agronomic characteristics is commonly used. Because this is not the ultimate solution, the DNA marker approach has benefited the modern plant breeding. Therefore an easy approach by using one kind of primer have been developed from random amplification of polymorphic DNA sequences (RAPD) to discriminate effectively between different cultivars of Cucuma species Methods and Results : DNAs were extracted from the harvested roots of Cucuma sp. using DNeasy plant Mini kit (Qiagen, Hilen, Germany). These plants cultivated from GARES (Hamyang) and used for PCR amplification. The relative concentration of the extracted DNA was estimated Nano Drop ND-1000 (NanoDrop Technologies, Wklmington, De, USA) and final DNA concentration was adjusted to 5.5 ng/㎕. In this study 9 primer pairs were tested on 8 Cucuma sp. These primers showed polymorphism in Cucuma sp. The cluster dendogram showed that the similarity coefficients ranged from 0.68 to 0.87, CUR02 turned out to be CUR11, and CUR16 is similar to CUR17. Conclusion : These finding could be used for further research on cultivar development by using molecular breeding techniques and for conservation of the genetic diversity of Cucuma species. These data on polymorphism difference based on RAPD will be give us invaluable breeding information by selection of superior lines.

Retroperitoneal fibrosis (RPF) is a rare disease characterized by the presence of retroperitoneal tissue marked by chronic inflammation and prominent fibrosis. A 67-year-old man presented with general weakness and oliguria. Laboratory findings showed blood urea nitrogen 77.7 mg/dL, serum creatinine 9.24 mg/dL, and an IgG4 level within the normal range. Computed tomography (CT) findings showed bilateral hydronephrosis and distal ureteral obstruction due to fibrotic adhesion to a presacral mass. Laparoscopic biopsy was performed. The authors report a case of acute kidney injury caused by non-IgG4 related focal retroperitoneal fibrosis in the pelvis that was successfully treated using prednisolone and tamoxifen… non-IgG4 related focal retroperitoneal fibrosis caused byacute kidney injury.
