Biologists face an overwhelming richness of nucleotide and protein sequence data. By the middle of 2005, there were almost 300 complete genomes that were publicly accessible. Most of these were archeal or bacterial since prokaryotic genomes are much smaller than eukaryotic genomes. Among eukaryotes, fungi, particularly yeasts, have some of the smallest genome sizes and hence represent the highest number of complete or almost complete genomes sequenced. By mid-2005, there were over 43 fungal genomes that were completely or almost completely sequenced and publicly accessible. What are the relationships among fungi and between fungi and other organisms? What type of genes and pathways are required for pathogenicity and other fungal lifestyles? Researchers are addressing these types of questions with data from high-throughput genomic sequencing. This review examines some recent uses of fungal genomic data in comparative genome analyses. Comparative genomics can facilitate research into the following areas: evolution, phylogenetics, targeted drugs, gene discovery, and gene function. Each of these is discussed as well as the availability and ownership of the genomic data, and the concepts of homology (homologs, orthologs, paralogs) and similarity.
