Genetic erosions in plant cell cultures, especially in chromosome number and ploidy level, have now been known for over 25 years. Until the mid -1970ssuch changes were consideredundesirable and thereforediscarded because the main emphasis wason clonal propagation and genetic stability of cultures. However, since the publication on somaclonal variation by Larkin and Scowcroft (1981) there has been a renewed interest to utilize these in vitro obtained variations for crop improvement. Studies conduc- ted during the last decade have shown that callus cultures, especially on peridical subculturing over an extended period of time, undergo morpho- logical and genetic changes, i. e. polyploidy, aneuploidy, chromosome breakage, deletions, translocations, gene amplification, inversions, muta- tions, etc. In addition, there are changes at the molecular and biochemical levelsincluding changes in the DNA, enzymes,proteins, etc. Suchchanges are now intentionally induced, and useful variants are selected.For instance in agricultural crops such as potato, tomato, tobacco, maize, rice and sugarcane, plants showing tolerance to a number of diseases, viruses, herbicides and salinity, have been isolated in cell cultures. Likewise induction of male sterility in rice, and wheat showing various levels of fer- tility and gliadin, have been developed in vitro. These academic excercises open new avenues for plant breeders and pathologists. Another area of tremendous commercial importance in the pharmaceuti- cal industry is the selection of cell lines showing high levels of medicinal and industrial compounds. Already high shikonin containing somaclones in Lithospermum are being used commercially.

In continuation of Volumes 8, 9, 22, and 23, this new volume deals with the regeneration of plants from isolated protoplasts and genetic transformation in various species of Actinidia, Allocasuarina, Anthurium, Antirrhinum, Asparagus, Beta, Brassica, Carica, Casuarina, Cyphomandra, Eucalyptus, Ipomoea, Larix, Limonium, Liriodendron, Malus, Musa, Physcomitrella, Physalis, Picea, Rosa, Tagetes, Triticum, and Ulmus. These studies reflect the far-reaching implications of protoplast technology in genetic engineering of plants. The book contains a wealth of useful information for advanced students, teachers, and researchers in the field of plant tissue culture, molecular biology, genetic engineering, plant breeding, and general biotechnology.

This series ofbooks on the biotechnology of Medicinal and Aromatic Plants provides a survey of the literature focusing on recent information and the state of the art in tissue culture and the in vitro production of secondary metabolites. This book, Medicinal and Aromatic Plants VIII, like the previous seven volumes published in 1988, 1989, 1991, 1993, and 1994, is unique in its approach. It comprises 26 chapters dealing with the distribution, importance, conventional propagation, micropropagation, tissue culture studies and the in vitro production of important medicinal and pharmaceutical compounds in various species of Achillea, Anethum, Aquilaria, Arnica, Aspergillus, Astragalus, Catalpa, Chelidonium, Eremo- phila, Eucalyptus, Eucommia, Geranium, Heterocentron, Hypericum, Maclura, Morinda, Mortierella, Nicotiana, Phaseolus, Pinellia, Piqueria, Psorales, Rhodiola, Sanguisorba, Valeriana, and Vancouveria. This book is tailored to the needs of advanced students, teachers, and research scientists in the field of pharmacy, plant tissue culture, phytochemistry, biochemical engineering, and plant biotechnology in general.
