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.

Silicon Valley and the industrial districts of Italy, where shared identity, superior skills, regional specialization and trust-based networking among local firms have produced dynamic and flexible ecosystems, are inspiring examples of the successful promotion of thriving technology and business clusters. Cluster studies, besides acknowledging (the potential of) concentration and spill-overs in a dynamic network of larger companies and new start-up firms, also pay attention to the importance of investors, universities and other supportive institutions that contribute to the international and longer-term competitiveness of local industry clusters.

This book looks at why certain regions are successful in creating an innovative technology cluster (with chapters on Silicon Valley and the Italian Food districts) and why aspiring communities and districts seek to learn from those examples and create an internationally successful region or sector (with chapters on the Dutch Biopartner program to stimulate entrepreneurship in the life sciences, on high-tech Israel and on the Italian Slow Food Movement). In some cases internationally renowned universities and/or research laboratories inspire engineers and scientists to become entrepreneurs and take the lead in cluster development (e.g. in the chapters on Food Valley Wageningen, the Knowledge Pearl Leuven-Flanders and the Scandinavian Oresund cluster). In other cases indigenous flagship firms, collaborating with each other and outsourcing many activities to smaller companies, may act as a regiona (TM)s catalyst (e.g. in the chapters on Flanders Vegetable Valley, the Dutch horticultural industry and the Defence Diversification Agency in theUK). Chapters on North Carolinaa (TM)s Research Triangle Park and the recent initiative to stimulate innovativeness in East Netherlands show that also an active government can stimulate emerging clusters by making local resources and funds available (e.g. risk capital, high-quality infrastructure), attracting foreign firms to invest and building ties between the private sector, knowledge institutions and local authorities.
