Russian botanical gardens are actively involved in the conservation of rare and endangered plants. They pay special attention to the species included in the Red Book of the Russian Federation. At present, 377 species of higher plants are cultivated in living collections of botanical gardens out of 514 species presented in the Red Book of Russia, which is 73%. Thus, the Russian Federation has practically met the requirement of goal 8 of the Global Strategy for Plant Conservation. The vast majority of rare plant species are represented by samples in the collections of many botanical gardens and the reliability of their protection under cultural conditions is beyond doubt. In the Main Botanical Garden of the Russian Academy of Sciences, an in vitro collection of rare and endangered plants is preserved, including 82 species, which is 17.3% of the total number of angiosperms included in the Red Book of the Russian Federation. As a result of many years of research, the features of the cultivation and preservation of ex situ plants belonging to different families have been revealed. The main methodological aspects at the stages of obtaining a sterile culture, micropropagation proper and long-term deposition are reflected. The compositions of nutrient media and cultivation factors were optimized for slowed growth of explants of the studied cultures and preservation of their viability.

Nepenthes Khasiana

Ex-situ conservation is an important key in the management of rare, endangered and threatened (RET) plant species and its effectiveness depends on several factors. Maintenance of viable germplasm and its subsequent propagation plays an important role in long term conservation of many RET species. Nepenthes khasiana is a rare and gravely threatened species in the wild due to over-collection and other threats. The species needs urgent in-situ and ex-situ conservation. Development of easy to propagate techniques would pave faster multiplication for its use of educational, medicinal and horticultural purpose. In the present paper, successful propagation technique of Nepenthes khasiana through seeds is demonstrated along with detailed information on precautions to be taken during the adoption of the techniques.

The current investigation aimed to present an overview of the conservation of biological diversity of rare and endangered plant species. Methods of biodiversity conservation as well as several overview recommendations for the preservation of various rare species have been considered. An overview of the taxa included in the red book has been presented on the example of the Russian Federation. Global and local codes and classifiers of plant rarity were also presented. Future prospects for the conservation of biological diversity and the creation and development of bioresource collections have been considered.

Preservation Method

Abstract Ex situ storage plays an important role in the conservation of plant biodiversity. Cryopreservation at ultra-low temperatures (−  196 °C) is the only long-term ex situ preservation method for plant species that cannot be stored in seed banks. In the present study, we developed a cryopreservation protocol for micropropagated Rubus humulifolius (Rosaceae) plants representing currently critically endangered population of the species in Finland. Abscisic acid (ABA) has been found to increase the freezing tolerance of several plant species. Thus, we studied the effect of a 10-day pretreatment with 0, 2 or 4 mg/l ABA in comparison to freshly dissected buds. We also studied how the duration of in vitro subculture affects cryopreservation result. The ABA pretreatment had divergent effect on control and cryopreserved buds: the regeneration of non-cryopreserved control buds increased from 51% to 70%, 90% or 87% while the regeneration of cryopreserved buds decreased from 52% to 35%, 6% or 9% after 0, 2 or 4 mg/l ABA pre-treatments, respectively. Buds from plants subcultured for 1 month had 63% survival, which, however, decreased to 29% or nil% after 2 or 4 months subculture. The regenerated plants were successfully transferred from in vitro to in vivo conditions in common garden. Growing in garden is needed for future restoration of the species in wild. Cryostorage and other ex situ conservation actions carried out in botanical gardens may be of increasing importance as a tool to maintain plant biodiversity in the future.

The paper presents the results of research on the bioecological features of 8 species of herbaceous plants (Ixiliorion tataricum, Convallaria majalis, Ornithogalum fischeranum, Convolvulus persicus, Iris aphylla, Tulipa sogdiana, Tulipa schrenkii, Tulipa biflora), included in the Red Book of the Republic of Kazakhstan (6 species), the Russian Federation (1 species) and the Mangistau region (1 species) when introduced under the conditions of the Mangyshlak Experimental Botanical Garden. Bioecological features of plants, life forms, their biometric indicators, results of phenological observations in conditions ex situ of Mangyshlak experimental botanical garden are given. Of the 8 studied species, 6 are ephemeroids, 2 species are long-growing. All plants go through all phases of vegetation, successfully reproduce by seed and vegetation ways. Morphometric indices of research objects exceed similar data in places of natural growth, which indicates stability in culture conditions. Following the results of the introduction into the culture, a seed fund of rare and endangered plants was laid; the use of species in ornamental gardening of the Mangistau region was proposed.

Endemic Plant Species

Endemic plant species are usually more vulnerable to anthropogenic threats and natural changes and, therefore, hold a higher extinction risk. The preservation of these species is a major concern on a worldwide context and in situ protection alone will not guarantee their conservation. Ex situ conservation measures must be undertaken to support the conservation of these species, and seed banking is the more efficient and cost-effective method. However, when seed banking is not an option, alternative approaches should be considered. Biotechnological tools provide new and complementary options for plant conservation including short-, medium-, and long-term strategies, and their application for plant species conservation has increased considerably in the last years. This review provides information about the status of the use biotechnology-based techniques for the conservation of endemic plant species. Particular attention is given to cryopreservation, since is the only long-term ex situ conservation strategy that can complement and support the other conservation measures. The cryopreservation of plant genetic resources is, however, more focused on crop or economically important species and few studies are available for endemic plant species. The plant material used, the cryopreservation methods employed, and the assessment of cryogenic effects are reviewed. The reasons to explain the difficulties in cryopreserving these species are discussed and new strategies are proposed to facilitate and increase the interest on this matter. We expect that further studies on the conservation of endemic plant species will increase in a near future, thus contributing to maintain these valuable genetic resources.

The creation of rare plant species collections in vitro is one form of natural flora protection and effectivemethod of ex situ gene pool conservation. The results of introducing in vitro more than 80 rare plant species from the RedBook of Russia are summarized. The clonal micropropagation protocols allowing to obtain a sufficient plants number inorder to restore natural populations and preserve rare plant species were developed. The conditions for a long deposit havebeen specified. The optimal explant types for long-term conservation in vitro were determined for plants of different lifeforms: shoot fragments containing one or two metameres for woody and semi-woody plants, renewal buds for herbaceousplants, bulbils or their segments for bulbous plants.
