Although only about 3 years have passed since the preparation of the original manuscript of this book for the Russian edition, the number of successful experiments on somatic hybridization of higher plants has doubled. Although the main inferences of the first edition still remain in force, most of them have received conclusive experimental support and, moreover, some new con clusions have been drawn. It can be expected that these inferences and conclusions will constitute a more or less durable foundation for somatic cell genetics of higher plants. We thus hope this book will also remain useful over the next years, in spite of the rapid progress of experiments and the increase in the number of scientific reports in this field. Though it might appear strange to an uninvolved observer, the principal progress in hybridization of somatic cells of higher plants has been due to plant physiologists (who entered the field by elaborating methods and techniques for plant cell and, later, for isolated protoplast culture) rather than plant geneticists. However, further qualitative improvement in this field is inconceivable without the instillation of genetic ideology and the strict logic of genetic experiments. The main purpose ofthis book is the attempt to organize the available experimental data in terms and cate gories of genetic analysis. For this reason, this book lays no claim on being a comprehensive treatise on somatic hybridization.

1 John H. Dodds The culture offragmen ts of plant tissue is not a particularly new science, in fact as long ago as 1893 Rechinger (1893) described the formation of callus on isolated fragments of stems and roots. The culture of plant tissues in vitro on a nutrient medium was performed by Haberlandt (1902), however, his attempts were unsuccessful because he chose too simple a medium that lacked critical growth factors. Over the last fifty years there has been a surge of development in plant tissue culture techniques and a host of techniques are now avail able (Dodds and Roberts, 1982). The major areas are as follows. Callus Culture Callus is a rather ill-dermed material. but is usually described as an un organised proliferating mass of tissue. Although callus cultures have a great deal of potential in the biotechnological aspects of tissue culture, i.e. secondary product formation, they are not very suitable for plant propagation. The key reason for their unsuitability is that genetic aber rations occur during mitotic divisions in callus growth (D'amato.l965). The aberrations can be of a major type, such as aneuploidy or endo reduplication. It follows therefore that the genetic status of the re generated plants is different from that of the parent type. In general terms this genetic instability is undesirable, but there are occasions when a callus stage can be purposely included to diversify the genetic base of the crop.

Yeast Protocols contains many key techniques for studying the biology of yeasts at both the cellular and molecular levels. Working primarily from Saccharomyces cerevisiae, the expert contributors explain step-by-step how to successfully isolate, identify, and culture yeasts; the secrets of meiotic mapping; how to use PFGE in karyotyping and gene localization; the methods for purification and analysis of various cell components; and the construction and exploitation of genomic DNA clone banks. They also cover the latest methods for chromosome engineering, insertional mutagenesis by Ty elements, mRNA abundance and half-life measurements, the use of reporter gene systems, genotoxicity testing, and more. Yeast Protocols follows the widely applauded Humana Methods in Molecular Biology style: brief introductions putting the particular method in context, comprehensive lists of materials, cookbook style instructions, and troubleshooting notes to avoid common pitfalls and solve problems. The techniques can be used with confidence and success by both inexperienced newcomers and established researchers.

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.

Isolated protoplasts are a unique tool for genetic manipulation of plants. Since the discovery of a method for the enzymatic isolation of pro-· toplasts by Professor E. C. Cocking in 1960, tremendous progress has been made in this very fascinating area of research. I have witnessed the struggle in the 1960's and early 1970's, when obtaining a clean prepara tion of protoplasts was considered an achievement. I also shared the pioneering excitement and enthusiasm in this field during the 2nd Inter national Congress of Plant Tissue Culture held at Strasbourg in 1970, where Dr. I. Thkebe of Japan presented his work on the induction of division in tobacco protoplasts. This was followed by my participation in three international conferences devoted to plant protoplasts held in 1972 in Salamanca (Spain) and Versailles (France), and then in 1975 in Nottingham (England). The enthusiasm shown by plant scientists at these meetings was ample proof of the bright future of protoplast technology, and it became evident that protoplasts would playa major role in plant biotechnology, especially in genetic engineering. Since then we have never looked back, and now the methods for isolation, fusion, and culture, as well as regeneration of somatic hybrids, have become routine laboratory procedures for most plant species. Currently the focus is on cereal and tree protoplasts. In order to bring about any genetic manipulation through fusion, in corporation of DNA, and transformation, the regeneration of the entire plant through manipulation of protoplasts is a prerequisite.

Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species. Utilization of wild relatives of a crop depends largely upon its crossability relations with cultivated varieties. Sev eral wild species are not crossable with the commercial cultivars due to various isolation barriers. Furthermore, in a few cases, hybridiza tion is possible only in one direction and reciprocal crosses are not successful, thus depriving the utilization of desired cytoplasm of many species. However, techniques have been developed to over come many barriers and hybrid plants are produced. New crop species have been developed by overcoming the F 1 sterility and producing amphidiploids and such crops are commercially being grown in the field. The segregation pattern ofF 1 hybrids produced by distant hybridization in segregating generations are different from the intervarietal hybrids. In former cases, generally, unidirectional segregation takes place in early generations and accordingly, selec tion procedures are adopted. In most of the cases, backcross or modified backcross methods have been followed to utilize wild species, and thus numerous types of resistance and other economical attributes have been transferred in the recurrent parents. Protoplast fusion has been amply demonstrated in a number of cases where sexual hybridization was not possible and, as a result, hybrids have been produced.
