Plant genetic resources in China and their application to plant biotechnology

Qing Fu Chen 한국작물학회 2007 한국작물학회 학술발표대회 논문집 Vol.2007 No.11

Plant germplasm resources are the plant materials containing useful inheritable characters of actual or potential value. Generally speaking, plant resources include cultivated and wild plants. China is a megadiversity country. A great lot of different complex climate environments in China such as dryness, wetness, clearness, clouding, shade, plain, hill, mountain, and so on, have gestated many Chinese endemic special plants. Some of them have special genes, such as resistance to drought, chilliness, disease, pests, and saltness etc, elite quality, high yield characteristics and so on. There are 470 families、about 3 7000 genus、more than 30 000 species of lichen, fern、seed plants in China. Special species in China involve 200 genus and about 10 000 species. Plant resources in China are conservated in situ and ex situ, by means of reforestation, regrassing, natural protection zones, arboreta, campus, parks, and institutes, etc. National Crop Gene Bank in Beijing, built in 1986, has 3200m2, two long-term rooms (T=-18℃±1℃, RH<50%) with the capability 400,000. There are more than 340,000 accessions in long-term banks of the National Crop Gene Bank of China, involving 35 families, 192 genus, 725 species. Among them, 80% are native to China. Up to now, there have been more than 210 main tree species for artificial forestation in China. Among them, there are more than 120 species for reforestation of barren slopes, deserts, and stony mountains. There are about 800-1000 Chinese traditional medicine plants, which were mainly conservated in situ and ex situ. The application of plant germplasm in China in plant biotechnology were reviewed on the following aspects: (1)Core germplasm construction by molecular marker technology (2)Plant germplasm preservation by biotechnology (3) Plant germplasm reproduction and industrialization by biotechnology (4) Elite gene discoverfrom plant germplasm by biotechnology (5) Plant germplasm in China and gene engineering technology. At last, some problems of plant resources in China were put forward.

姜炳華,沈相仁,李相珏,朴壽現 韓國作物學會 1997 Korean journal of crop science Vol.42 No.2

우리나라의 자원식물 중 식용으로 이용할 수 있는 식물종에 대한 연구로서 식용자원의 발생 이황에 대한 연구와 유전자원 수집을 통해 얻어진 결과는 다음과 같다. 1. 우리나라에 발생하는 식용 자원식물 중 74 개과에 속하는 609종의 발생이 확인되었다. 2. 식용 자원식물의 수에 다른 과별 순위는 국화과>백합과>십자화과>콩과>장미과>산형과>화본과>석죽과 순으로 나타났다. 3. 국화과, 십자화과, 백합과에 속하는 대부분의 식용식물은 경엽부를 채소로서 이용하고 있었으며, 장미과의 식물과 콩과 식물 중 일부는 과실이나 종자를 식용 자원으로 이용할 수 있었다. 4. 재배하는 작물종과 식물분류학적으로 근연관계에 있는 종의 수가 많은 화본과 식물은 직접 식용으로 이용할 수 있는 종의 수가 극히 적었다. 5. 수집된 종자들의 발아률은 종마다 다양하여 자원식물의 식용을 위해서는 발아율의 낮은 종의 발아율 개선에 대한 연구가 선행되어야 한다. This study was conducted to obtain the basic information of edible resources among plant species. Potentials of resource plants were important in various usages, healthy food, medicinal materials, and breeding materials. Through our investigation 609 species of resources plants were considered as edible resources. These species belong to 74 families in which Asteraceae, Poaceae, Fabaceae, and Rosaceae were major families. Brassicaceae, Liliaceae, and Asteraceae contained large numbers of edible plants because plants belonged to these families were mainly used as vegetable. But Cyperaceae and Poaceae had relatively small numbers of species in the category of edible plant because plants belonged to these families have not been used directly as vegetables, common usage of edible plant. But Poaceae have a potentials as genetic donor for resistance-breeding strategies in major cereals. Although Poaceae can not be used as food directly, Poaceae should be investigated intensely in future for improvement of major cereals or application as fodder plants. The beneficial traits of edible plants as breeding materials have not been studied yet and development of new crop from plant resources requires the information about current situation in occurrence of resources plants genetically related to current crop species. Our results do not cover all plant species in Korea but this classification and identification about edible resources will provide primary information about plant resources. The collected seeds of resource plants showed wide spectrum in germination rate among plant species. The germination rate would probably be affected by collecting times, collected stage, and stored period. The proper methods about improving germination rate have to be elucidated to propagate the resource plants.

불교 경전 속 식물 연구의 의의와 활용 방안

민태영 동아시아불교문화학회 2015 동아시아불교문화 Vol.0 No.21

In Buddhist scriptures, the plants appear a variety of ways that it related the Buddha’s life as well as representing the Buddhist doctrine and becoming an object of metaphor or symbol. So, I proposed that clarifying the plants in Buddhist scriptures and studying the plants Buddhist and botanically was new method for easy to understand Buddhist doctrine. Also, in a broad sense, Buddhism contains not only the Buddha’s word but culture, I emphasized that study plants in Buddhist scriptures should be used as a basis for development of Buddhist cultural products. Because still early stage, the research level is revealing name and properties of plants, arranging plants on the use of scriptures and doctrine and classifying resource plants of the Buddha’s birthplace-oriented plants. However, in the future, plants in Buddhist scriptures are made a judgment that it can be performing a role as enough materials of the Buddhist culture products as well as an axis of contents development. Especially if we have pay attention to aspect of resource plants through continuous research, besides a useful plant resources, we can provide Buddhist cultural things to see by utilization and plantation of plants based on Buddhist philosophy for landscaping around the temples. Also utilizing Buddhist theme park as the Buddhist culture space, expansion of the base of Buddhism and Buddhist culture can be expected. 불교 경전 속에는 붓다의 생애와 관련된 식물과 더불어 불교의 교리를 대변하거나 비유와 상징의 대상이 되는 등 다양한 방식으로 식물이 등장한다. 따라서 불교 경전 속의 식물을 명확히 밝혀내어 불교적으로나 식물학적으로 규명하는 연구는 불교의 교리를 쉽게 이해하게 하는 새로운 방식이라는 점을 제시하였다. 또한, 넓은 의미에서의 불교는 단순히 붓다의 말씀 뿐 아니라 문화를 포함하고 있다는 점을 인식하고 불교 경전 속 식물 연구를 불교 문화상품 개발의 기초 자료로서 활용할 수 있어야 한다는 논지를 정리하였다. 아직은 관련 연구가 초기 단계여서 식물명과 특성을 밝혀내는 정도이고 교리와 경전에서의 활용 중심으로 식물들을 정리한다거나 붓다의 탄생지 식물들을 대상으로 자원식물학적으로 분류를 해놓은 정도에 머물고 있다. 그러나 향후 경전 속의 식물들은 불교 문화상품의 소재로서나 불교 콘텐츠 개발의 한 축으로서도 충분한 역할을 수행할 수 있다고 판단된다. 특히 지속적인 연구를 통해 자원식물학적인 측면으로도 관심을 기울인다면 유용한 자원식물로서 뿐 아니라 우리나라 사찰 주변의 조경에 있어서도 보다 불교 철학과 사상에 입각하여 식물을 활용하고 식재하여 불교적인 볼거리를 제공할 수 있다. 특히 불교문화 공간으로서의 불교 테마 공원 조성에 활용함으로써 불교와 불교문화의 저변 확대도 기대할 수 있다.

2009년 3월부터 10월까지 경상남도 합천군일대의 자원식물분포조사를 수행하였다. 본 조사를 통해 확인된 조사지역내의 소산 관속식물은 82과 292속 427종 4아종 49변종 9품종으로 총 489분류군으로 확인되었다. 조사 지역에서 분포하고 있는 식물의 자원 유용도를 분석한 결과, 식용자원식물이 187분류군, 섬유용 자원식물이 9분류군, 약용 자원식물이 137분류군, 관상용 자원식물이 52분류군, 초지 자원식물이 126분류군, 공업원료자원이 2분류군, 염료용 자원식물이 112분류군, 목재용 자원식물이 16분류군, 용도가 밝혀지지 않은 식물이 134분류군로 구분되었다 특기할만한 식물로는 한국 특산 관속식물이 총 18분류군, 환경부지정 특정식물종이 33분류군, 희귀식물은 2분류군으로 각각 조사되었고, 귀화식물은 44분류군으로서 전체분류군의 약 8.9%를 차지하였다. 한편 조사지역의 식생은 비교적 양호한 편이었으나, 레저시설이 형성되거나, 중계소, 사찰 등으로 인한 임도와, 저지대의 많은 농경지로 인해, 귀화식물의 분포가 빠르게 확산될 우려가 크므로 이에 따른 적절한 조치가 필요할 것으로 판단된다. The flora for resource plants in Hapcheon-gun were investigated 10 times from March to October, 2009. Based on collected voucher specimens, the flora of this area consisted of 489 taxa in total; 82 families, 292 genera, 427 species, 4 subspecies, 49 varieties and 9 forms. The resources plants in the area were categorized by usage into 9 groups including an unknown group: 187 edible, 126 pasturing, 137 medicinal, 112 dyeing, 52 ornamental, 16 timber, 9 fiber, 2 industrial taxa and 134 unknown resource plants were recorded respectively. In addition, there were 18 taxa of Korean endemic plants, 33 taxa of specific plants which were designated by the Ministry of Environment, and 2 taxa of rare plants. Furthermore, 44 taxa of naturalized plants were observedin this investigated area. The vegetation status of the investigated area was well conserved, but it is likely that the contaminated area could be rapidly increased and exacerbated by the climbers and development of forest roads. Therefore, the systems for conservation need to be prepared for the effective management of forests, and there must be special rules to control the number of climbers and visitors.

식물유전자원관련 국제협약 및 국제협상에 관한 최근동향

The current international debate on legal regimes for plant genetic resources has its origins in the late 1970s and early 1980s when developing countries became concerned over the inequity of continuing the free flow of genetic resources. Two major international instruments that handle these important issues are the Convention on Biological Diversity (CBD) and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA). The Convention on Biological Diversity was adopted in 1992, at the Earth Summit, held in Rio de Janeiro. Currently, 196 countries are parties to the CBD. The Conservation of Biological Diversity, the sustainable use of their components, and the equitable sharing of the benefits arising from the use of the genetic resources are the objectives of the CBD. The Convention on Biological Diversity reaffirmed the sovereign rights of countries over their own biological resources and established that states have the authority to determine access to genetic resources under their jurisdiction. Under the CBD, the individual or institution seeking to collect or receive biological samples must get the Prior Informed Consent (PIC) from the national authority. The applicant and the national authority must negotiate the Mutually Agreed Terms (MAT) for the use of the material and the sharing of the benefit. The International Treaty on Plant Genetic Resources for Food and Agriculture was negotiated to address the outstanding issues not resolved by the CBD. The ITPGRFA entered into force on June 29, 2004 after ratification by 40 countries. The IT creates a Multilateral System (MLS) for access and benefit sharing that creates a common pool of PGRFA for research and breeding. The scope of the MLS extends to the crops and forages listed in the Annex 1 of the Treaty which are under the management and control of the government and are in the public domain. In order to make the MLS, the Treaty member countries agreed the text of a Standard Material Agreement (SMTA) to be used for all the transfers of Plant Genetic Resources for Food and Agriculture (PGRFA) within the system. The SMTA is a contract between the provider and the user of the resources. Today, scientists and other professionals dealing with plant genetic resources cannot access, develop or conserve these resources without negotiating their way through a complex set of laws and policies. There are different measures governments need to adopt to advance the implementation of these regimes. Therefore, this paper is an attempt to give genetic resources professionals and related scientists the information they need to be more sensitive to the policy and legal environment in which they do their work. 유전자원과 관련이 된 국제 규범은 생물다양성협약(Convention on Biological Diversity) 과 식량농업 식물유전자원국제조약(International Treaty on Plant Genetic Resources for Food and Agriculture)의 두개의 규범이 있다. 이러한 국제적 규범에 따라서 종전에는 유전자원은 인류의 공동유산으로 간주되어 누구에게나 자유롭게 접근 활용이 가능하였던 것이 유전자원에 대한 국가 주권이 인정되면서 유전자원의 활용에 따라 발생하는 이익에 대하여 공정하고 균등한 분배를 해야 하는 등 유전자원에 대한 소유권 개념에 커다란 변화가 오고 있다. CBD에서는 유전자원의 접근 및 이익공유에 사전통보승인(PIC), 상호동의조건(MAT)을 명문화하여 유전자원에 접근 및 활용이 쌍자간의 협의에 의하여야 함을 의무화 하고 있다. 이와 대조적으로 IT에서는 64개의 식량농업유전자원에 대해서는 다자체제(Multilateral System)하에서 표준물질이전계약서(Standard Material Transfer Agreement)를 통하여 접근 및 활용이 가능하도록 규정 하므로써 농업용 유전자원의 원활한 접근 및 활용을 완화하는 추세이다. 이밖에도 유전자원 관련 한 국제협약으로 신품종 보호연맹(UPOV), 무역관련지식재산권 협약(TRIPS), 세계무역기구(WTO), 세계지식재산권기구(WIPO)등이 있어 유전자원의 소유권과 이들에 대한 접근에 대한 국제적 논의도 활발하게 진행이 되고 있어 유전자원을 일선에서 다루고 있는 종자은행의 과학자나 유전자원관련 정책입안자, 종묘업계나 육종가들도 시시각각으로 변화하고 있는 유전자원관련 국제정책과 규범에 대하여 충분한 지식을 가질 것이 요구된다. 우리나라도 2009년 초 정식으로 IT회원국이 됨에 따라서 다자체제하에서 각국회원국 보유 유전자원 및 국제농업연구센터 보유 유전자원에 대한 접근이 가능해졌으며 아울러 우리나라 국가연구기관 보존 유전자원에 대해서도 외국의 접근을 허용해야 하는 의무도 함께 발생하였다. 이러한 국제적 추세에 발맞추어 우리나라도 2008년 8월부터 유전자원보존관리 및 이용에 관한 국내법을 제정하여 시행하고 있으며 다른 여러 나라들도 국가수준에서의 IT 이행을 위하여 많은 노력을 기울이고 있으며 특히 다자체제 하에서의 유전자원 접근 및 이익공유 이행을 서두르고 있다.

Assessment on Antioxidant Potential and Enzyme Activity of Some Economic Resource Plants

Boo, Hee-Ock,Shin, Jeoung-Hwa,Shin, Ji-San,Choung, Eui-Su,Bang, Mi-Ae,Choi, Kyung-Min,Song, Won-Seob The Plant Resources Society of Korea 2012 한국자원식물학회지 Vol.25 No.3

The antioxidant potential and enzyme activities in Salicornia herbacea, Corylopsis coreana, Erythronium japonicum, Phragmites communis, Momordica Charantia, Nelumbo nucifera, Salvia plebeia, Portulaca oleracea, Ficus carica, Citrus junos and Cornus officinalis were determined. Their antioxidant activities were measured using DPPH radical scavenging and nitrite scavenging activity. Enzyme activities in investigated plants were evaluated as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX). The DPPH scavenging rate from 100 to 2500 $mgL^{-1}$ was the highest in the flower of Corylopsis coreana. However, it was not detected in most of the samples at concentration below 100 $mgL^{-1}$. The nitrite scavenging activity according to each kind of resource plants was significantly higher in the stem of Corylopsis coreana and leaf of Nelumbo nucifera. The root extract of Erythronium japonicum had the highest SOD enzyme activity of 94.0% while leaf of Salvia plebeia showed the lowest SOD enzyme activity of 30.4%. The activity of CAT and APX showed higher values in the stem of Corylopsis coreana, root of Erythronium japonicum and root of Phragmites communis in comparison with other plants. The activity of POD showed significantly high values in stem of Corylopsis coreana, Momordica Charantia and pericarp of Citrus junos extracts. The antioxidant enzyme activities differ significantly in different plants. In conclusion, we showed that Corylopsis coreana, Erythronium japonicum Cornus officinalis, and Momordica Charantia had the potent biological activities. Therefore, these plant resources showing antioxidant activity could be good materials for development of source of functional healthy food.
