  • Objectives : Official Arisaematis Rhizoma is described only three species, Arisaema amurnse, Arisaema erubescens, and Arisaema heterophyllum, in national Pharmacopoeia. However, other Arisaema species, Arisaema ringens, Arisaema takesimense and Arisaema serratum, also have been distributed as an inauthentic Arisaematis Rhizoma in the herbal market. To develop a reliable molecular authentication method for Arisaematis Rhizoma in species level, we analyzed DNA barcode regions using six Arisaema species. Methods : Thirty-eight samples of six Arisaema plants species (A. amurense, A. amurense f. serratum, A. heterophyllum, A. takesimense, and A. serratum) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL gene) were analyzed after PCR amplification. The species-specific sequences and phylogenetic relations were estimated using entire sequences of three DNA barcodes based on the analysis of ClastalW and UPGMA, respectively. Results : The comparative analysis of DNA barcode sequences were revealed inter-species specific nucleotides to distinguish the medicinal plant of Arisaema Rhizoma in species levels excluding between A. amurense and its subspecies (A. amurense f. serratum) and A. takesimense and A. serratum, respectively. However, we obtained sequence differences enough to discriminate authentic and inauthentic Arisaematis Rhizoma. Therefore, we suggest that these SNP type molecular genetic markers were an reliable method avaliable to identify official herbal medicines. Conclusions : These marker nucleotides could be useful to identify the official herbal medicines by providing definitive information that can identify original medicinal plant and distinguish from inauthentic adulterants and substitutes.

  • Objectives : The origin of Breeae Herba (So-gye) and Cirsii Herba (Dae-gye) is differently prescribed in Korean and Chinese modern pharmacopoeia. Since the similar morphological characteristics and chaotic plant names, moreover, the aerial part of Carduus crispus have been used as the Cirsii Herba. To develop a reliable method for correct identification of these herbal medicines and to evaluate the genetic relationship of these closely related plant species, we analyzed sequences of DNA barcode regions. Methods : Thirty-one samples of 6 medicinal plants (B. segeta, B. setosa, C. japonicum var. maackii, C. setidens, C. chanroenicum, and C. crispus) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL) were analyzed after amplification using appropriate primers reported in previous studies. The nucleotides of species-specific authentic marker and phylogenetic relations were estimated based on the entire sequences of DNA barcodes by the analysis of ClastalW and UPGMA, respectively. Results : In comparative analysis of DNA barcode sequences, we obtained specific nucleotides to discriminate the medicinal plant of Breeae/Cirsii Herba in species level and evaluated the phylogenetic relationship of these species. Futhermore, we identified distinct marker nucleotides enough to authenticate respective species. These sequence differences at corresponding positions were avaliable genetic markers to determine the botanical origins of Breeae Herbal as well as Cirsii Herba. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by providing of definitive information that can identify each plant species and distinguish from unauthentic adulterants and substitutes.

  • 벼의 약 및 현미 배양효율과 관련된 DNA marker를 이용하여 인디카형 벼 품종인 'IR 36'의 조직배양 효율을 개선하기 위하여 실험한 결과를 요약하면 다음과 같다. 벼품종 간에 약 및 현미배양 효율을 비교한 결과 자포니카 > 통일형 > 인디카 형의 순으로 나타났다. 그러나 MGRI집단의 약배양에서 식물체분화율이 높은 계통으로 선발된 'MGRI 079'와 'MGRI 036'의 약배양 효율은 각각 19.8%, 19.9%로 가장 높게 나타났다. 'MGRI 079'에 'IR 36'이 여교배되어 양성된 $BC_2F_4$ 90 계통에 대한 marker검정을 실시하여 positive band를 나타내는 34계통을 선발할 수 있었다. 선발된 34계통 중 10 계통의 약배양에서 캘러스 형성률은 'IR 36' 보다 현저히 높았다. 선발된 10 계통의 현미배양에서도 캘러스형성 능력과 식물체재분화율이 'IR 36' 보다 높게 나타났다. $BC_2F_4$ 계통 중에서 식물체분화능력이 높은 계통으로 선발된 $BC_2F_4$-28은 간장이 'IR 36'보다 큰 편이었으나 출수기와 미립특성은 'IR 36'과 비슷하였다.

  • 본 연구는 큰느타리버섯의 베타글루칸 고함유 형질에 관련된 SCAR marker를 개발하기 위해 수행되었다. operon사의 OPA(20개), OPB(20개), OPL(20개), OPP(20개), OPR(20개), OPS(20개) 등 총 120개 primer를 random primer(10 mer)로 사용하여 대립 계통 9종과 베타글루칸 고함유 계통 9 종을 대상으로 RAPD를 이용한 bulked segregant analysis를 실시하여 OP-R03 primer로부터 대립 계통에는 나타나지 않고 베타글루칸 고함유 계통에만 나타나는 특이적인 RAPD 밴드를 얻었다. OP-R03 primer를 이용한 RAPD 결과, 약 91 bp 부근에서 베타글루칸 고함유 계통에 특이적인 DNA 밴드가 관찰되었으며 이 DNA 밴드의 염기서열 말단을 근거로 SCAR 마커로 사용할 specific primer인 OP-R03-1-F와 OP-R03-1-R를 디자인하였다. SCAR 마커 OP-R03-1-F/-1-R primer를 이용하여 PCR을 수행한 결과에서도 91 bp 부근에서 대립 계통과 구별되는 DNA 밴드가 베타글루칸 고함유 계통에서 확인되었으며 random primer인 OP-R03 primer를 이용하여 PCR을 수행했을 때보다 재현성이 높고 진한 DNA 밴드임을 확인할 수 있었다.

  • Korean L. leiolepis of the genus Leontopodium could be discriminate from the foreign L. alpinum using random amplified polymorphic DNA (RAPD). Among the 12 URP markers used for the detection, the URP-5 marker and the URP-7 marker detected polymorphic DNA bands, ranging from 400-1000 bp in the size of amplified DNA fragments.
