an excellent contribution to the British Mycological Society symposium series...focuses on recent developments in methods for gene manipulation in fungi together with specific examples of how these techniques are being used to exploit industrially important species for use in heterologous gene expression and strain improvement and for the analysis of plant fungal pathogenesis...the editors and authors of this volume have produced an excellent reference source for biotechnologists in industrial mycology as well as for institutional libraries serving students of fungal molecular biology. Kerry O'Donnell, Mycologia ...an excellent review of all the rapid developments made in these fields in the last decade. MCS-SMC Bulletin It may sound like an oxymoron, but gene transfer technology still has its major applications in basic research. For example, it can be used to identify pathogenicity genes in phytopathogenic fungi (Oliver et al.)...Overall, the chapters are well referenced and the book is well produced. It will serve as a useful point of departure to anyone contemplating novel applications of gene transfer technology, particularly in the less-studied fungi. Durgadas P. Kasbekar, The Quarterly Review of Biology
