   Abstract

   Endemic plants are species that are native to a specific geographical region and are found nowhere else. These plants are crucial for maintaining biodiversity and ecosystem balance; some of them have special characteristics like Rafflesia arnoldii (Indonesia), which has the largest individual flower, and Cycas beddomei (India), an endangered cycad species endemic to India, important for its prehistoric lineage and medicinal values like rosy periwinkle (Catharanthus roseus), which has a source of alkaloids used in cancer treatment, particularly in drugs like vincristine and vinblastine, which are vital in treating leukemia and Hodgkin’s disease. Neelakurinji (Strobilanthes kunthiana), endemic to India, is traditionally used in Ayurvedic medicine for its supposed anti-inflammatory and rejuvenating properties. Conservation of endemic plants is essential to preserve the unique ecosystems they support and to prevent the loss of irreplaceable plant species. Conventional conservation approaches include in situ methods like protecting natural habitats, creating national parks, and establishing reserves to safeguard plants in their natural environments. Ex situ methods, such as seed banks, botanical gardens, and nurseries, focus on conserving plants outside their natural habitats for research and restoration purposes. In contrast, biotechnical approaches offer innovative solutions for conservation, utilizing tools like tissue culture, cryopreservation, and genetic engineering. These techniques allow for the propagation and preservation of endangered species, helping to overcome challenges like habitat fragmentation and limited population sizes. Combining both conventional and biotechnical methods is key to ensuring the long-term survival of endemic plants, as each approach complements the other by addressing different aspects of conservation challenges.

5. Plant Genetic Resources: Their Conservation and Utilization Through Various Strategies Involving Modern Genomic Tools and Traditional and Cultural Methodologies

   Vinod Janardan Dhole, J. Souframanien, P. Dhanasekar

   Abstract

   Plant genetic resources (PGRs) including landraces, wild relatives, obsolete varieties, and modern cultivars are of significant value for food and agriculture. Their conservation is non-negotiable for effectively tackling critical challenges like pests, diseases, and climate change, which are essential for achieving and sustaining global food security. Successful PGR conservation demands a robust strategy that integrates in situ (natural habitats) and ex situ (seed banks, gene banks, cryopreservation, botanical gardens) methods. Community engagement is vital to fully leverage indigenous knowledge and implement participatory breeding programmes that support conservation of locally adapted crops. To optimize the utility of PGR, national and international policies should be refined to foster access and benefit sharing while incentivizing conservation efforts. The adoption of modern technologies, including digital databases and genomic tools, is absolutely needed to improve the monitoring and maximize the use of genetic resources. Conclusively, integrating traditional knowledge with modern tools is key to preserving valuable PGR, sustaining genetic diversity, mitigating biodiversity losses, bolstering food systems, and ensuring long-term global food security and ecological balance.

6. Role of Seed Banks in the Conservation of Plant Diversity and Ecological Restoration

   Anjani Kumar

   Abstract

   The numerous significant traits of plant species are improved by the incorporation of desired genes from germplasm. This germplasm is pronounced by several terms such as plant genetic resource, genetic resource, gene pool, and genetic stock. Therefore, conservation as well as preservation of these useful genetic stocks is a very important task in crop improvement programmes. However, the chief losses of this genetic material such as germplasm are possible because of gradual loss in it. The meaning of genetic erosion is the reduction of genetic diversity from various crop species, wild species, and wild relative in gene banks as well as seed banks. The conservation of germplasm or crop genetic resources is achieved mainly by two processes, viz. in situ conservation and ex situ conservation. A convenient procedure for conservation of a particular germplasm or crop genetic resource is a seed bank because of its significance. Seed bank is a place where plants are conserved as seeds known as seed bank. A seed bank comes under the classification of gene bank; consequently, the major role of a seed bank is to preserve genetic diversity to maintain ecological balance. The preservation of germplasm or crop genetic resources are appropriate in the form of seed because it requires smaller area than storage in the form of whole plant. There are currently more than a thousand seed banks that exist all over the world, depending on their type and size. The main objective for maintaining the seed bank is successful sustainable management and conservation of biodiversity through plant breeders developing disease-resistant, nutritional, drought-tolerant varieties in various crop species. Consequently, seed banks and gene bank have played a dynamic approach to the supporting in conservation as well as sustainable use of plants. This book chapter discusses every aspect related to storage of seed in gene bank or seed banks for the appropriate execution of genetic diversity and sustains biological balance.

   Shivani Bhutani, Manali Singh, Nisha Dinkar

   Abstract

   The several kinds of in vitro instruments and techniques that are employed to preserve the genetic diversity of endangered and uncommon plant species worldwide have been covered in this article. Species that are at risk of going eradicated due to the swift loss of genetic variety and habitat are mostly found in places with limited resources, in underdeveloped regions of the world, in hotspots for biodiversity worldwide, and in island nations. Since only a few tiny populations, or perhaps just a few individuals, of these endemic species are left in the wild, they are special. This compilation of articles explains the direct use of cryopreservation and in vitro techniques, as well as the efforts being made in many places to prevent the extinction of plants. These contributions also offer advice on rare plant propagation, covering methods for large-scale propagation, preservation, and reintroduction.

8. Plant Genetic Resources Conservation by Cryopreservation

   K. Kavinaya Shri, A. Pavithra, Vivek Pazhamalai, S. S. Meenambiga, S. Ivo Romauld

   Abstract

   Cryopreservation is one of the significant biotechnological approaches that has conserved plant genetic resources destroyed by habitat loss, climate change, and overexploitation. The method ensures long-term preservation of plant tissues, cells, and seeds at ultra-low temperatures that halt biological degradation and keep genetic materials safe for further use. Cryopreservation is a method that does not assimilate the characteristics of any other conservation methods, for its genetic materials are maintained in a stable form and hence apt to preserve rare and endangered species. It also assists with in situ conservation when it controls diseases and pests and acts as a gene bank, increasing diversity in reproductive techniques. Cryopreservation has recently been significant for sustainable food security by conserving the crop genetic diversity required to adapt to the agricultural challenges posed by climate change. Cryopreservation is one of the critical components for future directions, which will further support the preservation of genetic resources necessary for ecosystem restoration and innovative agriculture. This chapter highlights cryopreservation techniques, applications, and their vital role in plant genetic resource conservation, biodiversity, and sustainable resource management.

    Mehrana Koohi-Dehkordi, Mozhdeh Shafaei, Sara Ghasemzadeh, Mehran E. Shariatpanahi

    Abstract

    Biotechnology greatly enhances the efficacy of plant conservation strategies. Techniques including tissue culture, cryopreservation, and molecular markers hold the options in regeneration, conservation, and genetic assessment of the plant genetic assets. Through cryopreservation, long-ternetic diversity in naturalm conservation programs can store plant germplasm, and this does not lead to the loss of sensitivity, while through tissue culture, large quantities of endangered species of plants can be regenerated. Furthermore, molecular methods allow for the evaluation of population/genotypic variability, which is crucial when it comes to auspices for creating improved adaptability of species. As the rate of biological diversity declines so rapidly, these applications represent essential biotools in establishing and supporting sustainable systems of agriculture and ecosystems. The combination of biotechnology in conserving the natural plant diversity and other conventional approaches is important in the conservation of ecosystems and the management of plant genetic resources for sustainable development.

    Abstract

    Plant genetic resource conservation is essential for biodiversity, food security, and ecosystem sustainability. Seed banks and field germplasm collections serve as a foundation for conserving plant genetic resources. However, the use of molecular tools in plant conservation has improved the understanding and management of genetic resources. Molecular techniques such as DNA barcoding, marker-assisted selection (MAS), and next-generation sequencing (NGS) have enabled accurate identification and monitoring of genetic diversity across plant species. These molecular approaches facilitate the evaluation of genetic variability and the detection of rare or endangered genetic trait genotypes. Molecular markers such as amplified fragment length polymorphism (AFLP), SSRs, and SNPs are particularly valuable for assessing plant populations and guiding breeding programs for improving crops. Additionally, molecular data availability bolsters ex situ and in situ conservation efforts by mitigating genetic erosion and supporting the restoration of plant species and ecosystems. Integrating molecular tools with conventional methods offers a comprehensive framework for preserving PGRs. This combined approach is crucial for addressing challenges posed by habitat loss, climate change, and the overexploitation of plant species.

    Abstract

    The conservation of plant genetic resources (PGRs) has been recognized as an essential strategy to sustainable agriculture and enhance biodiversity. Notably, the application of DNA banks to support conservation is a new area in PGR conservation that is evolving but is proven to be extremely useful and practical. In the unlikely scenario that seed storage or in vitro methods are ineffective, DNA banking has been claimed to represent genetic control, which includes rebreeding. It preserves the actual gene pool for several years. This approach has a greater implication in conserving recalcitrant-seeded species that cannot be preserved using conventional methods, enhancing genetic resources conserved in particular. By the use of molecular techniques like DNA barcoding and genotyping, the effectiveness of DNA banks is enhanced to facilitate proper identification and determination of genetic diversity within and between species. Currently, new advances in science and technology will make it easier for us to recognize what is most important to the improvement of crops, there being many more challenges fomented by climate change and ever-increasing importance of ensuring a food supply. Furthermore, global approaches supporting the preservation of crop wild relatives and underused species in normal conservation plans, usually forgotten, could be enhanced by DNA banks. In brief, the strategic utilization of DNA banks is an innovative strategy to promote genetic resource conservation in order to ensure that future generations can rely on the genetic diversity which is vital to sustainable agriculture.
