  • Genomic DNA from the muscle of marsh clam (Corbicula leana) from Gochang, Muan and a Chinese site was extracted to identify genetic differences and similarity by randomly amplified polymorphic DNAs-polymerase chain reaction (RAPD- PCR). Out of 20 primers, seven primers produced amplified fragments which were consistently polymorphic. A total of 1,246 amplified products were produced of which 530 were polymorphic $(42.5\%)$. The number of polymorphic bands produced per primer varied from 40 to 122 with an average of 75.7 in marsh clam from Gochang. 3.28 of the 23.0 polymorphic bands per lane were found to be polymorphic. Also, about $4.34\%$ of total polymorphic bands were specific to marsh clam from Gochang. The major common bands of 0.28 kb generated by primer OPB-15 (GGAGGGTGTT) were present in every individuals, which were polymorphic. This common bands in every individuals should be diagnostic of specific strains, species and/or their relatedness. Primer OPB-19 (ACCCCCGAAG) produced the highest number of 12 specific bands. The intra-population variation was revealed in the band patterns identified by this primer. The random primer OPB-12 (CCTTGACGCA) yielded the amplified fragments which were consistently polymorphic between the marsh clams from Gochang and from Muan. This primer produced a total of 77 polymorphic bands: 31 bands from Gochang, 14 from Muan and 32 from the Chinese populations. An average of polymorphic bands were 1.8 from Gochang and 2.5 from the Chinese populations. This value obtained from the Chinese population was higher than those from the two domestic populations. Generally, the RAPD polymorphism generated by these primers may be useful as a genetic marker for strain or population identification of marsh clam.

  • Major diseases in grafted cacti have been reported and Fusarium oxysporum, Bipolaris cactivora, Phytophthora spp. and Collectotrichum spp. are known as causal pathogens. These pathogens can lead to plant death after infection. Therefore, some European countries have quarantined imported cacti that are infected with specific fungal pathogens. Consequently, we developed PCR detection methods to identify four quarantined fungal pathogens and reduce export rejection rates of Korean grafted cacti. The pathogen specific primer sets F.oF-F.oR, B.CF-B.CR, P.nF-P.nR, and P.cF-P.CR were tested for F. oxysporum, B.cactivora, P. nicotinae, and P. cactorum, respectively. The F.oF-F.oR primer set was designed from the Fusarium ITS region; the B.CF-B.CR and P.nF-P.nR primers respectively from Bipolaris and Phytophthora ITS1; and the P.cF-P.CR primer set from the Ypt1protein gene region. The quarantine fungal pathogen primer pairs were amplified to the specific number of base pairs in each of the following fungal pathogens: 210-bp (F. oxysporum), 510-bp (B. cactivora), 313-bp (P. nicotinae), and 447-bp (P. cactorum). The detection limit for the mono- and multiplex PCR primer sets was 0.1 ng of template DNA under in vitro conditions. Therefore, each primer set successfully diagnosed contamination of quarantine pathogens in export grafted cacti. Consequently, our methodology is a viable tool to screen contamination of the fungal pathogen in exported grafted cacti.

  • The selected seven oligonucleotides primers BION-32, BION-33, BION-35, BION-38, BION-40, BION-46 and BION-58 generated the shared loci, specific loci, unique shared loci to each population and shared loci by the three T. granosa populations in Beolgyo, a Chinese site and Wonsan, respectively. The bandsharing value between individuals' no. 03 and no. 04 was 0.816, which was the highest value identified within the Beolgyo population. The primer BION-35 generated the most loci (a total of 70), with an average of 10.0 in the Wonsan population. On average, seven oligonucleotides primers generated 16.1 specific loci in the Beolgyo population, 22.3 in the Chinese population and 39.3 in the Wonsan population. 126 unique shared loci to each population, with an average of 18 per primer, were observed in the Beolgyo population, 63 loci, with an average of 9 per primer, were observed in the Chinese population, and 49 loci, with an average of 7 per primer, and were observed in the Wonsan population. The oligonucleotides primer BION-32 generated 14 unique loci to each population, which were identifying each population in the Beolgyo population. Interestingly, every primer had not distinguished the shared loci by the three populations, major and/or minor fragments of sizes, which were identical in almost all of the samples. As regards average bandsharing value (BS) results, individuals from Beolgyo population ($0.717{\pm}0.057$) exhibited higher BS values than did those from Wonsan population ($0.552{\pm}0.104$) (P < 0.05). The dendrogram resulted from truthful seven oligonucleotides primers, representing three genetic clusters comprising group I (BEOLGYO 01, 02, 03, 04, 05, 06 and 07), group II (CHINESE 08, 09, 10, 11, 12, 13 and 14) and group III (WONSAN 15, 16, 17, 18, 19, 20 and 21). In three T. granosa populations, the longest genetic distance (0.874) displaying significant molecular difference was also between individual no. 02 within the Beolgyo population and individual no. 12 within the Chinese population. Relatively, individuals of the CHINESE population were fairly closely related to those of the WONSAN population.

  • 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.

  • Human enteric Adenovirus-41 (HuEAdV-41) causes gastroenteritis, which detected by the polymerase chain reaction (PCR) base diagnostic system for clinical, food, environmental, fish and shellfish samples. We developed improved PCR and nested PCR primer set which had high specificity, sensitivity and reduced times. In this study, we compared seventeen conditions reported in the previous study that was using the PCR based HuEAdV-41 detection system, and non-enteric Adenovirus were detected in nine conditions. The most sensitive detection condition was up to 25 copies however it took 184 minutes of PCR reaction time. In this study, the PCR primer set developed had same level of sensitivity, it reduced the time of detection for clinical, food and seafood samples to 112 minutes. Developed nested PCR primer set needed 112 minutes but detected up to approximately 1 copy. In addition, developed PCR and nested PCR primer set was validated with twenty samples of underground water at random, of which ten samples showed specific band without non-specific reaction. We expect this study will be used to diagnose HuEAdV-41 from various samples.

  • 한약재로 사용되는 방풍류는 절단되어 유통되므로 외부 형태적인 특징만으로 구분하기가 어려워 방풍류로 사용되는 방풍, 식방풍, 석방풍, 갯방풍 등 4종에 대해 PCR에 기초한 RAPD 마커를 이용하여 SCAR 마커를 개발하고자 하였다. RAPD 분석결과 밴드의 패턴은 다양하게 나타났으며 다형성의 밴드 수는 총 215개로 전체 밴드수의 98%였다. RAPD 분석에서 각 방풍류를 구별 할 수 있는 특이적인 밴드를 나타내는 primer는 방풍에서 4개의 primer, 식방풍은 6개의 primer, 석방풍은 4개의 primer, 갯방풍은 6개의 primer를 선발하였고, 그 중 특히 primer 425는 4종의 방풍류의 감별에 유용하였고, 이를 이용하여 SCAR마커로 전환하는데 이용하였다. 특이적인 단편을 클로닝하여 염기서열 분석으로 특이 primer를 제작하고 제작된 primer로 방풍류 시료 16개에 적용하였을 때, 국내의 야생에서 주로 자생하는 석방풍은 215 bp, 그리고 국내에서 가장 많이 재배 또는 생산되는 갯방풍은 177 bp와 300 bp에서 뚜렷하게 나타났다. 따라서 갯방풍과 석방풍의 감별 가능성을 제시할 수 있으며 개발된 SCAR 마커를 이용하여 시중에 유통되고 있는 방풍류 건조약재의 감별에 유용한 마커로 활용될 수 있을 것이다.

  • 본 연구는 multiplex PCR 방법을 적용하여 질 내부에 서식하는 유산균을 동시에 그리고 신속하게 검출하는 방법을 개발하는 것을 목적으로 수행되었다. 세균의 감염에 의한 질염 증상이 없는 건강한 20대 여성 166명으로부터 질 분비물을 채취하였다. 건강한 여성의 질 내부에 서식하는 것으로 확인된 Lactobacillus 속에 속하는 6종의 유산균을 종 특이 multiplex PCR primer를 제작하기 위해 선정하였다. Multiplex primer I은 L. iners, L. crispatus, L. gasseri를 선택적으로 검출하기 위해 특성화하였고 multiplex primer II는 L. acidophilus, L. jensenii, L. fermentum를 선택적으로 검출하기 위해 특성화하였다. Multiplex PCR 기술을 이용하여 분석한 결과 L. crispatus (77%)가 가장 높은 빈도로 검출되었고 L. acidophilus (57%)과 L. jensenii (57%)는 상대적으로 높은 빈도로 검출되었다. L. iners (59%)는 L. acidophilus (57%)와 L. jensenii (57%) 보다 높은 빈도로 검출되었지만 항생제 치료 과정 후 또는 세균성 질염의 경우에도 발견되는 균종으로 건강한 여성에게서 주로 서식하는 종이라고 결론 내리기는 어렵다. 결론적으로, 특정 유산균의 특이적인 primer를 이용한 multiplex PCR 기술은 질의 건강상태의 변화 또는 질의 질병으로부터 회복 과정을 예측할 수 있는 도구로서 유용할 것으로 생각된다.
