Genetic Reserve

In the context of climate change, in situ conservation of plant genetic resources is becoming increasingly important as it supports natural (ecological and evolutionary) adaptations of plants to the changing environment. The aim of this study was to synthesize a comprehensive general methodology for the maintenance of genetic reserve sites of medicinal plants based on the analysis of relevant legal documents, literature sources, databases, and authors’ own experience. A methodology was developed for the application of various maintenance measures for target species populations in genetic reserve sites to ensure their long-term sustainability. It uses a systematic approach to the intervention measures by grouping them into habitat-specific and factor-specific ones, and follows the specific principles of biodiversity conservation, such as the concept of ecosystem, priority of in situ conservation, caution and validity of decision-making, and regional approach. An extensive discussion on major intervention measures is provided. The methodology is intended to be used as a tool for the preparation and implementation of management plans of individual medicinal plant genetic reserve sites by the responsible agencies and protected area managers and is directly linked to the implementation of the EU (European Union) Biodiversity Strategy to 2030 at the national level.

To facilitate the updating ofin situandex situconservation strategies for wild taxa of the genusHordeumL., a combined ecogeographic survey and gap analysis was undertaken. The analysis was based on the Global Inventory of Barley Plant Genetic Resources held by ICARDA plus additional datasets, resulting in a database containing 17,131 wildHordeumaccessions. The analysis concluded that a genetic reserve should be established in the Mendoza Province of Argentina, as this is the most species-rich area globally forHordeum. A network of reserves should also be set up across the Fertile Crescent in Israel, Palestine, Syria, Jordan, Lebanon and Turkey to provide effective conservation within the centres of diversity for gene pools 1B (Hordeum vulgaresubsp.spontaneum(C. Koch) Thell.) and 2 (Hordeum bulbosumL.). The majority of the species were deemed under-collected, so further collecting missions are required worldwide where possible. Althoughex situandin situconservation strategies have been developed, there needs to be further investigation into the ecological environments thatHordeumspecies occupy to ensure that any adaptive traits expressed are fully conserved. Additionally, studies are required to characterize existing collections and test the viability of rare species accessions held in genebanks to determine whether furtherex situcollections are required alongside the proposedin situconservation.

The aim of the article is to summarize the results of plant gene pool samples introduction into the National Plant Genebank from different countries and ecological and geographical zones for use in domestic breeding. Results and Discussion. In 2016 – 2018, 5984 samples were introduced to the Centre for Plant Genetic Resources of Ukraine using various information sources, including 2093 samples from Ukraine and 3891 from foreign countries. The greatest samples variety was attracted by cereals, leguminous, fodder, medicinal and essential oil, vegetable and melon crops, corn. Seeds of new forms having valuable properties are attached from research and breeding institutions of Ukraine. The samples of foreign origin were most actively introduced through cooperation with research institutions of Russia, Belarus, and Moldova. A significant number of samples came from genebanks in Europe: the Czech Republic, Italy, France, Germany, the Netherlands; Asia: Kazakhstan Turkey, Israel, China as well as from South (Mexico) and North America - USA, Canada. The ways of pre-adaptation and adaptation of samples from geographically remote regions for use in Ukraine are indicated. To collect local cultural and wild-growing samples of different crops, collecting missions were carried out in the central and southern regions of the forest-steppe and northeastern regions of Ukraine during which 1641 gene pool samples were collected. For the Red Book species of plants and species that are not listed in the Red Book of Ukraine but are rare or are threatened with extinction under natural conditions, a points have been identified for possible arrangement of in situ conservation reserves. A number of objects with a rich genetic diversity of fodder and medicinal plants have been identified, on which it is necessary to monitor coenoses and ensure in situ conservation. The introduced samples were transferred for use in research and breeding programs in Ukraine. Conclusions. The definition of a model of ecologically adapted in Ukraine genotypes of different crops that are carriers of valuable traits from countries with similar climatic conditions as well as from geographically remote regions, has made it possible to increase the efficiency of introduction and to more specifically search and attract to the National Genebank the plant samples with the necessary manifestation levels of economic and biological traits.

Background. Plant genetic resources (PGR) conservation is an indispensable condition for ensuring the country’s economic and environmental security. The most important component of the PGR status assessment is the study of crop wild relatives in a particular region. Within the framework of the work on inventorying crop wild relatives (CWR) in the regions of Russia, an inventory of CWR was for the first time made for Magadan Province, Far East region of Russia, to identify plant taxa that are prioritized for conservation and monitoring of their status in natural phytocenoses. Materials and methods. The material for the present research was taken from the data published on the vegetation of the studied region. Taxonomic analysis of CWR was performed using conventional floristic methods. In order to select priority species for conservation, the guidelines for PGR conservation adapted for Russia were used.Results and conclusions. A list of 232 CWR species belonging to 62 genera of 21 families has been compiled; it encompasses nearly 20% of the entire regional flora. The indigenous part of CWR amounts to ca. 60%, while the adventive part includes 40% of the total CWR number. Analysis of distribution of CWR species over the studied area showed that the greatest diversity of CWR species (81%) is concentrated in the Okhotsky floristic district. As a result of the analysis, 76 species occurring in Magadan Province were identified for prioritized in situ conservation.

<p>Abandonment of planting of <em>Gossypium barbadense</em> has endangered its existence. The objective was to determine the characteristicof the maintenance of <em>Gossypium barbadense</em> in the Central-West Region of Brazil, with the aim to foster the conservation of the species. Expeditions were conducted in 2014-2015 in Southeast Goiás, where cotton collection has not been reported before. Data from previous collections in Goiás, Mato Grosso, Mato Grosso do Sul and Distrito Federal available in Albrana database were considered this study. In the Central-West Region of Brazil, 466 accesses of <em>G. barbadense</em> were recorded, found most frequently in backyards (91.4%), but also spontaneous plants (7.5%), farm boundary (0.8%) and commercial farming (0.2%) have also been found. The main use indicated by VDU was as medicinal plant (0.66), therefore this is the main reason for in situ preservation. However, this cultural habit has been abandoned, causing uncertainty about the continuity of preservation. There was presence of lint almost only in seeds of plants of the variety <em>brasiliense</em>. The most common fiber color was white, not cream color, suggesting that plants are derived from commercial cultivars used in the past. Hence, until 2015, the conservation relies on single plants almost exclusively in backyards for medicinal use, and there are no crops of this type of cotton for commercial purpose. The exploitation of the possible use both of the fiber as a medicinal plant would foster ex situ and in situ preservation of this important genetic resource.</p>

The International Coconut Genetic Resources Network (COGENT) is a global research network organized by the International Plant Genetic Resources Institute (IPGRI) in 1992 with support from member countries, the Consultative Group on International Agricultural Research (CGIAR), partner institutions, donor agencies, and by regional and international development organizations.                           In the last 12 years, COGENT has been fully operational with 38 member coconut producing countries in five regions (South Asia; Southeast and East Asia; South Pacific; Africa and the Indian Ocean; and Latin America and the Caribbean). It has successfully developed and disseminated to coconut breeders and curators worldwide the International Coconut Genetic Resources Database (CGRD). The CGRD contains characterization data and some pictures of 1,416 accessions which are conserved by national programmes in 28 sites in 23 countries. To further secure conserved germplasm, a COGENT multi-site International Coconut Genebank has been established to conserve 200 important accessions in each region. Coconut varieties with multi-purpose uses are being identified, documented and promoted. The performance of promising 38 high-yielding hybrids are being evaluated in a multilocation  trial involving four African and three Latin America/Caribbean countries to identify suitable varieties and hybrids for resource-poor farmers. Farmers’ varietal preferences in 15 countries are being evaluated. Diversity-linked income-generating activities are being used as a strategy to promote in situ and on-farm conservation and germplasm utilization have been initiated in 15 countries. Protocols for in vitro embryo culture, cryopreservation, morphometric and molecular marker-based methods for locating and characterizing diversity; pest risk assessment and germplasm health management are being developed, tested and upgraded. Strategies and techniques for farmer participatory research, collecting, characterization and ex situ and in situ conservation are being refined.   To strengthen the coconut research capability of COGENT member countries, the COGENT Secretariat and IPGRI have organized 39 country need assessment missions  and conducted 41 workshops and meetings involving 994 coconut researchers to share information and technologies, discuss issues and common problems and opportunities and how to address them; conducted 40 training courses involving 765 participants from 41 countries; supported 274  research and training/capacity building activities  in 30 countries; and led the establishment of the Global Coconut Research for Development Programme (PROCORD). IPGRI and COGENT's current priority involves the further promotion of more effective conservation and use of coconut genetic resources, both regionally and globally.
