The incidence of Cherry necrotic rusty mottle virus (CNRMV) and Cherry green ring mottle virus (CGRMV) have recently been occurred in Korea, posing a problem for sweet cherry cultivation. Since infected trees have symptomless leaves or ring-like spots on the pericarp, it is difficult to identify a viral infection. In this study, the incidence of CNRMV and CGRMV in sweet cherry in Gyeongbuk province was surveyed using a newly developed duplex reverse transcriptase polymerase chain reaction (RT-PCR) method that can detect both viruses in a single reaction. CNRMV and CGRMV co-infection rates were 29.6%, 53.6%, and 17.6%, respectively, in samples collected from three different sites (Daegu, Gyeongju and Gyeongsan) in Gyeongbuk province during 2012 and 2013. This duplex RT-PCR method offers a simple, rapid, and effective way of identifying CNRMV and CGRMV simultaneously in sweet cherry trees, which can aid in the management of viral infections that could undermine yield.

A multiplex polymerase chain reaction (PCR) detection kit for screening of four herbicide-tolerant genes (cp4 epsps, mepsps, pat, and bar) in genetically modified (GM) crops was developed. The kit was validated by three different laboratories, and the expected targets were specifically observed in 14 different herbicide-tolerant GM events. This method can be effectively and conveniently used to monitor approved and unapproved GM crops containing four herbicide-tolerant genes.

In this study, we developed a species-specific PCR assay for rapid and accurate detection of three Xanthomonas species, X. axonopodis pv. poinsettiicola (XAP), X. hyacinthi (XH) and X. campestris pv. zantedeschiae (XCZ), based on their draft genome sequences. XAP, XH and XCZ genomes consist of single chromosomes that contain 5,221, 4,395 and 7,986 protein coding genes, respectively. Species-specific primers were designed from variable regions of the draft genome sequence data and assessed by a PCR-based detection method. These primers were also tested for specificity against 17 allied Xanthomonas species as well as against the host DNA and the microbial community of the host surface. Three primer sets were found to be very specific and no amplification product was obtained with the host DNA and the microbial community of the host surface. In addition, a detection limit of $1pg/{\mu}l$ per PCR reaction was detected when these primer sets were used to amplify corresponding bacterial DNAs. Therefore, these primer sets and the developed species-specific PCR assay represent a valuable, sensitive, and rapid diagnostic tool that can be used to detect three specific pathogens at early stages of infection and may help control diseases.

Objectives : The aim of this study is to investigate that Sunghyangjeongki-San which has been frequently medicated in the early stage of stroke can protect against ischemic damage in rat brain Methods : Extracellular levels of amino acids(glutamate, aspartate, GABA, glycine, taurine, tyrosine, alanine), organic acids(pyruvate, lactate), and cerebral infarction volume were measured at the striatum of rats subjected to permanant focal cerebral ischemia induced by 2 hours of middle cerebral artery occiusion(MCAO). Rats were orally administered with Sunghyangjeongki-San at 30mins before MCAO and the microdialysate was collected by intracerebral microdialysis three times before MCAO and six times after MCAO at 20mins interval and analyzed by HPLC. After a microdialysis study, the brain was sliced and stained with cresyl violet buffer for the measurement of cerebral infarcted area and volume by image analyzer system Results : The concentrations of glutamate, aspartate, and tyrosine known as excitatory neurotransmitters were significantly decreased in Sunghyangjeongki-San group compared with control group, The concentrations of GABA, glycine, taurine and alanine known as inhibitory neurotransmitters were significantly increased in Sunghyangjeongki-San group compared with control group. The concentrations of pyruvate and lactate showed little significant change in Sunghyangjeongki-San group compared with control group. The measurement of cerebral infarcted area and volume by image analyzer system were significantly decreased in Sunghyangjeongki-San group compared with control group. Conclusions : Sunghyangjeongki-San can affect on protecting against cerebral ischemia by regulating extracellular levels of excitatory and inhibitory amino acid neurotransmitters and improve the conditions of the patients in the early stage of stroke.
Multiplex PCR Assay for Simultaneous Detection of Korean Quarantine Phytoplasmas

Multiplex PCR assays were developed for the simultaneous detection of ten important Korean quarantine phytoplasmas. The species-specific primers were designed based on ribosomal protein, putative preprotein translocase Y, immunodominant protein, elongation factor TU, chaperonin protein and the 16S rRNA genes of 'Candidatus (Ca.) Phytoplasma' species. Three main primer sets were prepared from ten designed primer pairs to limit nonspecific amplification as much as possible. The multiplex PCR assay using the three primer sets successfully amplified the correct conserved genes for each 'Ca. Phytoplasma' species. In addition, ten important 'Ca. Phytoplasma' species could be easily determined by recognizing band patterns specific for each phytoplasma species from three primer sets. Moreover, a high sensitivity of multiplex PCR for each primer set was observed for samples containing a low DNA concentration (10 ng/${\mu}l$). This study provides the useful multiplex PCR assay as a convenient method to detect the presence of ten important quarantine phytoplasmas in Korea.
Duplex PCR을 이용한 국내 미승인 유전자변형 감자(EH92-527-1)의 검사법 개발

우리나라에서 미승인 품목인 유전자변형 감자 EH92-527-1를 검출하기 위한 duplex PCR 검사법이 개발되었다. 감자의 내재유전자로 UDP-glucose pyrophosphorylase (UGP)가 선별되었고, 14개 다른 작물을 이용하여 특이성이 확인되었다. 유전자변형 감자에 삽입된 T-DNA 영역과 감자 게놈 사이의 연결 부위를 증폭하도록 프라이머 EH92-F/R 쌍이 제작되었고, 몇 개의 다른 유전자변형 작물을 이용하여 특이성이 확인되었다. 서론에서 언급한 바와 같이 BASF사에서 각 개발된 유전자변형 감자 EH92-527-1과 BPS-A1020-5가 GBSS 유전자를 동일하게 포함하고 있으나 본 연구에서 개발한 검사법은 event-specific primers를 이용하였기 때문에 유전자변형 감자 EH92-527-1에만 특이성을 나타낸다. 이와 같이 개발된 duplex PCR 검사법의 검정한계치는 약 0.05%이다. 이러한 duplex PCR 검사법이 우리나라에 미승인 유전자변형 감자의 모니터링에 유용하게 사용될 것으로 판단한다. A duplex polymerase chain reaction (PCR) method was developed to detect unapproved genetically modified (GM) potato (EH92-527-1) in Korea. The UDP-glucose pyrophosphorylase (UGP) gene was selected as an endogenous reference gene for potato and used to validate the specificity for 14 different crops. The primer pair EH92-F/R was designed to amplify the junction sequence between the genome and transgenic region introduced in GM potato. Its specificity was also validated using several different GM events. The detection limit of the duplex PCR method is approximately 0.05%. This duplex PCR method could be useful for monitoring cultivation of unauthorized GM potato in Korea.
