Conidial fungi or molds and mildews are widely used in modern biotechnology as producers of antibiotics and other secondary metabolites,industrially important enzymes,chemicals and food.They are also important pathogens of animals including humans and agricultural crops.These various applications and extremely versatile natural phenotypes have led to the constantly growing list of complete genomes which are now available.Functional genomics and proteomics widely exploit the genomic information to study the cell-wide impact of altered genes on the phenotype of an organism and its function.This allows for global analysis of the information flow from DNA to RNA to protein,but it is usually not sufficient for the description of the global phenotype of an organism.More recently,Phenotype MicroArray (PM) technology has been introduced as a tool to characterize the metabolism of a (wild) fungal strain or a mutant.In this article,we review the background of PM applications for fungi and the methodic requirements to obtain reliable results.We also report examples of the versatility of this tool.
