  • Magnoliae Flos (Sini in Korean) is one of the most important oriental medicinal plants. In the Korean Herbal Pharmacopeia, the bud of the all species in Manolia denudate and Manolia genus were regarded as the botanical sources for ‘Sini’. Most the dried bud of Manolia denudata, Manolia biondii and Manolia sprengeri were used as ‘Xin-yi’ in China. Therefore, the purpose of this study was to determine and compare the ‘Magnolia’ species, four species including Manolia denudata, M. biondii, M. liliiflora and M. Kobus were analysis of sequencing data revealed DNA polymorphisms. The based on tRNA coding leucine/phenylalanine (trnL-F) and NADH-plastoquinone oxidoreductase subunit 5 (ndhF) sequences in chloroplast DNA. For the identification of ‘Magnolia’ species, polymerase chain reaction (PCR) analysis of chloroplast DNA regions such as ndhF have proven an appropriate method. A single nucleotide polymorphism (SNP) has been identified between genuine “Sini” and their fraudulent and misuse. Specific PCR primers were designed from this polymorphic site within the sequence data, and were used to detect true plants via multiplex PCR.

  • Objectives : This study was carried out to identify DNA markers of "Allium sativum" be circulated from Korea and China, which is difficult to discriminate from morphological characters because of fragmental materials of bulb. That is, all these studies focused on the discrimination of Allium sativum L. But these day, Chinese A. sativum was in circulated Korean A. sativum in Korean medicine markets. Therefore, the purpose of our study was to develop molecular markers for discrimination between Korean A. sativum and imports from China. Methods : Materials were collected randomly from a markets in Korea and China and be analyzed with matK, ndhF and trnL-F regions of chloroplast DNA (cpDNA). We collected 45 A. sativum individuals from Korean and Chinese medicine markets, in 2013. Results : As a results, matK and ndhF regions of cpDNA was shown to be identify, Species that grow from warm place and cold place can divide as five SNP (Single nucleotide polymorphisms) markers in matK and ndhF genes. Also, in trnL-F regions, found one SNP that can divide Korean A. sativum and Chinese A. sativum. Conclusions : From the analysis of matK and ndhF regions of cpDNA, we presumed that three markers of cpDNA were found by useful marker that can distinguish Korean, Chinese, Warm place type, and Cold place type. Individual differences of Korean and Chinese was thought that appear in geographical difference and genetic difference by environment for long hour even if same species.

  • This study was conducted to clarify the phylogenetic position and relationships of Korean Poaceae taxa. A total of 438 taxa including 155 accessions of Korean Poaceae (representing 92% and 72% of Korean Poaceous genera and species, respectively) were employed for phylogeny reconstruction. Sequence data of eight chloroplast DNA markers were used for molecular phylogenetic analyses. The resulted phylogeny was mostly concordant with previous phylogenetic hypotheses, especially in terms of subfamilial and tribal relationships. Several taxa-specific indels were detected in the molecular phylogeny, including a 45 bp deletion in rps3 (PACMAD [Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae, Danthonioideae] clade), a 15 bp deletion in ndhF (Oryzeae + Phyllorachideae), a 6 bp deletion in trnLF (Poeae s.l.), and two (17 bp and 378 bp) deletions in atpF-H (Pooideae). The Korean Poaceae members were classified into 23 tribes, representing eight subfamilies. The subfamilial and tribal classifications of the Korean taxa were generally congruent with a recently published system, whereas some subtribes and genera were found to be non-monophyletic. The taxa included in the PACMAD clade (especially Andropogoneae) showed very weak and uncertain phylogenetic relationships, presumably to be due to evolutionary radiation and polyploidization. The reconstructed phylogeny can be utilized to update the taxonomic positions of the newly examined grass accessions.

  • 뽕나무과(Moraceae) 닥나무속(Broussonetia)의 품종에 대한 국내 연구동향으로는 잎의 성상이나 암꽃의 포길이, 엽신의 폭과 같은 수목학 분수학적 관점으로 특징을 파악하기 때문에 구분이 어려운 실정이다. 또한 닥나무(Broussonetia kazinoki Siebold)와 꾸지나무[Broussonetia papyrifera (L.) $L^{\prime}H{\acute{e}}r.$ ex Vent.]의 수목학적 특징이 유사하여 오동정의 사례가 발생하기도 한다. 닥나무의 향명은 다양하게 불리지만 그 분류기준은 명확하지 않다. 본 연구에서는 총 4개 마커(ITS, matK, trnL-F, ndhF)의 염기서열 분석과 분자계통학적 분류를 통해 닥나무와 꾸지나무의 교잡종으로 확인된 전라도지역 닥나무 8개체에 대하여 펄프제지 자원으로써의 특성을 확인하였다. 8개체 인피섬유의 형태학적 특징인 섬유장, 섬유폭, 섬유 내강(Lumen)폭을 통해 Runkel ratio, Slenderness ratio, Flexibility coefficient, Rigidity coefficient를 도출하고 종이의 기계적 강도, 내절도와의 상관관계, 섬유와 섬유간의 결합력 등을 예측하였다. 상기와 같은 연구결과는 유전형질이 동일한 전라도지역 닥나무의 형태학적 특성을 통해 펄프제지 공정에 영향을 미칠 수 있는 인자들을 분석 하였다. 이러한 특성에 따라 다양한 품질의 종이를 제조 할 수 있는 기초 자료로 제공될 것이다.

  • 닥나무(Paper mulberry)는 뽕나무과(Moraceae) 닥나무속(Broussonetia)에 속하는 낙엽 활엽 관목으로 중국, 일본, 한국 등에 자생하며 Hutchinson(1967)에 의하면 닥나무 속은 열대, 아열대, 난대지방에서 자라는 낙엽성 관목으로 세계적으로 약 6종이 있다고 보고되었다. 일반적으로 닥나무의 품종을 구분하는 것은 수목학적 관점으로 잎의 성상, 줄기의 색과 무늬 유무로 구분한다. 그러나 상기의 수목학적 특징은 닥나무(Broussonetia kazinoki Siebold)와 꾸지나무[Broussonetia papyrifera (L.) L'Her. ex Vent.]가 유사하여 오동정의 사례가 발생하기도 한다. 경상도지역에서는 닥나무를 참닥나무, 머구닥나무, 개닥나무 3가지의 향명으로 구분하고 있다. 본 연구에서는 경상도지역 9개체 닥나무를 대상으로 수목학적 특징을 확인하였다. 나아가 식물종의 기준을 명확히 규명하기 위하여 엽록체 속의 matK, trnL-F, ndhF, 3개 마커와 핵에 존재하는 ITS, 총 4개 마커의 염기서열을 생산하였고 상기 구간에서 얻어진 염기서열 비교분석 및 계통학적 분류를 통해 유연관계를 파악하였다. 수목학적 관점으로는 품종을 명확하게 구분하기가 어려웠으며 분자계통학적 연구로 모든 시료는 닥나무와 꾸지나무의 교잡종으로 확인되었다. 본 연구 결과는 우리나라 전통한지의 원재료로 사용되는 닥나무류 식물자원의 분류체계의 확립을 위한 기초자료로 활용 될 것이다.
