The genus Aspergillus intrudes upon many aspects of human society, with species of industrial, economic and medical importance. As a consequence, many researchers will want to have a readable but authoritive overview of current knowledge and approaches for the Aspergillus species in their area. At 238 pages, this slim volume fills that gap admirably. Its approach is firmly post-genomic, emphasizing the new insights that can be gained using the 10 genomes from 8 species already available to support proteomics, metabolomics, bioinformatics and computer modelling. This is perhaps a model of what is to come for other fungal genera. The only obvious gap is the absence of a chapter on opportunistic pathogenicity, the forte of A. fumigatus. To compensate, systems biology approaches, industrial applications and secondary metabolism are covered particularly thoroughly over several chapters. This book will be a good institutional purchase to support advanced teaching but also for personal or laboratory purchase for researchers within industry.
