DOWNLOAD EBOOK →Isolated plant protoplasts are 'naked' cells that have had their cell wall removed either by mechanical action or by enzymic digestion. As a result of wall removal the only barrier that exists between the cell protoplasm and the external environment is the plasma membrane. The removal of the cell wall has drastic osmotic consequences for the isolated cell. Rather like animal cells, the isolated protoplasts must be maintained in an osmotically balanced (isotonic) nutrient medium or they will burst. As will be seen later, the isolation of plant protoplasts is not a particularly new event; as early as the 1890s scientists were isolating protoplasts mechanically and studying effects such as protoplast streaming. What has brought protoplast technology to the forefront of plant biology is the potential application of these structures in non-traditional plant improvement methods. Extreme care must be exercised by the reader, however, in be lieving some of the claims that have been put forward for the use of protoplasts in improvement programmes. In the 20 years since the first experiments in routine enzyme isolation of large numbers of protoplasts no real improvement has been obtained in a commercial crop plant. This does not mean that improvement is impossible; it simply indicates that it may be a longer term objective than some people would like to admit.

DOWNLOAD EBOOK →Until now, information on fungal protoplasts has been scattered throughout various sources. With authoritative reviews of protoplast isolation and applications in fungal biology research, Fungal Protoplasts: Applications in Biochemistry and Genetics is the first volume devoted to a major area in experimental mycology-fungal protoplasts. Written by 18 pioneering experts, this unmatched, illustrated reference presents well-established knowledge of protoplast research as well as newer ideas and methods. The book encompasses advances in protoplast isolation techniques and methodology, uses of protoplasts in physiological, biochemical, and genetic studies, and developments in protoplast fusion that form the basis for transformation and gene cloning experiments, including applications in industrial biotechnology. This fact-filled book also features end-of-chapter bibliographies for further research.

DOWNLOAD EBOOK →In the series of International Protoplast Symposia the Symposium of 1987 was held in Wageningen (The Netherlands). Earlier Symposia took place in Jena (DDR) 1963, Brno (CSSR) 1967, Salamanca (Spain) 1971, Nottingham (UK) 1975, Szeged (Hungary) 1979 and Basel (Switzerland) 1983. This 7th International Protoplast Symposium was organized by K.J. Puite (Secretary), J.J.M. Dons (Treasurer), H.J.Huizing and E.J.L. Hotke-Staal (Local Organizers), the first three persons being scientists, respectively, from the Research Institute Ital, the Institute for horticultural plant breeding IVT and the Foundation for agricultural plant breeding SVP at Wageningen. Scientific Advisers of the Symposium were A. J. Kool, M. Koornneef and F.A. Krens. The International Agricultural Centre lAC served as the Symposium location. The Organizing Committee decided that the scientific programme of the Symposium should be mainly focussed on protoplast technology of relevance to plant breeding. Therefore research on microbial protoplasts and on secondary metabolites was not included. About 250 scientists from 27 different countries were welcomed at the meeting. Speakers at Symposium Sessions and authors of Poster contributions were asked to hand over their manuscripts for the Symposium Proceedings already at the meeting, permit ting early publication of the Proceedings. These manuscripts give the state of the art of the protoplast research and illustrate the progress since the last Protoplast Symposium.
