Available in PDF, EPUB and Kindle. Book excerpt: Ex situ preservation of germplasm for higher plant species has been accom plished using either seeds or clones, but storage of these under typical condi tions does not provide the extreme longevities that are needed to minimize risk of loss. Costs of maintenance and regeneration of stocks are also high. Systems that provide virtually indefinite storage should supplement existing methods and it is within this context that cryopreservation is presented. The use of low temperature preservation was initially more a concern of medicine and animal breeding, and was expanded to plants in the 1970s. Sur vival after cryogenic exposure has now been demonstrated for diverse plant groups including algae, bryophytes, fungi and higher plants. If survival is com monplace, then the eventual application is a cryopreservation system, whereby cells, tissues and organs are held indefinitely for use, often in the unforeseen future. The increasing interest and capabilities for application could not have occurred at a more opportune time since expanding human populations have placed unprecedented pressures on plant diversity. This book emphasizes cry opreservation of higher plants and was initially driven by the concern for loss of diversity in crops and the recognized need that this diversity would be essential for continued improvement of the many plants used by society for food, health and shelter. The interest in cryopreservation has been expanded by conservationists and their concerns for retaining, as much as possible, the diversity of natural populations. The need for cryopreservation, thus, is well established.

This book was released on 2013-03-09 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The germ plasm of numerous plant species, especially those of forest trees, some agricultural crops, and medicinal plants, is endangered and threatened with extinction. This depletion of germplasm pools and the shrinkage of naturally occurring genetic resources have caused international concern. Conventionally, the germplasm of plants is conserved through seeds, tubers, roots, corms, rhizomes, bulbs, cuttings, etc. However, the germ plasm of a number of trees and plantation crops (such as coconut, cocao, coffee, oil palm, rubber, mango, horse chestnut, etc. ) cannot be preserved since their seed are short-lived (recalcitrant). Likewise, germplasm of vegetatively propagated crops (such as potato and cassava) cannot be stored on a long term basis and has to be grown and multiplied periodically in nurseries and fields. The plants are thus exposed to unpredictable weather conditions and diseases, with the result that instances are known where entire genetic stocks are lost. Therefore, unconventional methods are being developed for the storage and international exchange of germplasm. For this purpose in vitro cultures have been employed, but they can only enable short-to medium term preservation; moreover, cell cultures upon repeated subculture undergo genetic erosion. In view of the recent developments in the in vitro induction of genetic variability through somaclonal variation, somatic hybridization, recombinant DNA technology, etc. , new methods need to be employed for the storage of desirable cultures. In this regard freeze preservation of cells in liquid nitrogen (-196 0q, like that of semen, enables long-term storage, theoretically, for an indefinite period of time.
Download or read book Current Frontiers in Cryopreservation written by Igor Katkov and published by IntechOpen. This book was released on 2012-03-14 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost a decade has passed since the last textbook on the science of cryobiology, Life in the Frozen State, was published. Recently, there have been some serious tectonic shifts in cryobiology which were perhaps not seen on the surface but will have a profound effect on both the future of cryobiology and the development of new cryopreservation methods. We feel that it is time to revise the previous paradigms and dogmas, discuss the conceptually new cryobiological ideas, and introduce the recently emerged practical protocols for cryopreservation. The present books, "Current Frontiers in Cryobiology" and "Current Frontiers in Cryopreservation" will serve the purpose. This is a global effort by scientists from 27 countries from all continents and we hope it will be interesting to a wide audience.

Book excerpt: Cryopreservation has proven to be an important tool for the storage and conservation of plant genetic resources. This book is a unique resource for plant scientists, providing more than 100 ready-to-use cryopreservation protocols for plant types from algae and bryophytes to a range of flowering plants. It includes techniques for diverse plant parts such as dormant buds, pollen, and apical meristems and for cell types such as suspension and callus cultures.
Download or read book Conservation of Tropical Plant Species written by M.N. Normah and published by Springer Science & Business Media. This book was released on 2012-08-04 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is designed to provide a review on the methods and current status of conservation of the tropical plant species. It will also provide the information on the richness of the tropical plant diversity, the need to conserve, and the potential utilization of the genetic resources. Future perspectives of conservation of tropical species will be discussed. Besides being useful to researchers and graduate students in the field, we hope to create a reference for a much wider audience who are interested in conservation of tropical plant diversity.

Available in PDF, EPUB and Kindle. Book excerpt: Whole plants have been regenerated from isolated protoplasts, cells, tissues, and organs freeze-preserved in liquid nitrogen. Thus cryopreservation has proved to be an important tool for the storage and conservation of plant genetic resources. Numerous experts have contributed to this volume, which is divided into the following sections: General introduction into the cryopreservation of plant cells, tissues, organs and seeds; trees; cereals and grasses; legumes and oilseed crops; fruits, vegetables, tuber and root crops; medicinal, aromatic and ornamental plants.

Available in PDF, EPUB and Kindle. Book excerpt: Cryopreservation (liquid nitrogen-196 °C) represents the only safe and cost-effective option for long-term conservation of plant germplasm. Classical cryopreservation techniques, which are based on freeze-induced dehydration, are suitable for freezing undifferentiated cultures and apices of cold-tolerant species. New cryopreservation techniques, which are based on vitrification, are successfully employed with all explants, including cell suspensions and calluses, apices, and somatic and zygotic embryos of temperate and tropical species of medicinal plants. The development of cryopreservation protocols is significantly more advanced for vegetatively-propagated species than for recalcitrant seed species. Technology has been developed for long-term cryopreservation of nuclear genetic diversity in the form of pollen. Besides the already existing role of pollen cryobanks in breeding, there are many promising applications which have come into focus with the recent advances in allied bioscientific areas. There are a growing number of examples where cryopreservation is employed on a large-scale for different types of materials, including seeds with orthodox and intermediate storage behavior, dormant buds, pollen, biotechnology products, and apices sampled from in vitro plantlets of vegetatively-propagated species. In addition to germplasm conservation, cryopreservation also ensures genetic stability and retention of biosynthetic potential. Various explants have been used for cryopreservation of medicinally important plants. The present review takes stock of the developments in this area with a special reference to medicinal plants.

Available in PDF, EPUB and Kindle. Book excerpt: Until 10 years ago, cryopreservation protocols for plant tissues were mainly based on slow freezing in the presence of cryoprotective mixtures containing DMSO (dimthyl slphoxide), sugars, glycerol and/ or proline. Slow freezing results in a freeze-dehydration, leaving less water in the cells to form lethal ice crystals upon exposure to extreme low temperatures.
