Abstract
Members of the septin gene family are involved in cytokinesis and the organization of new growth in organisms as diverse as yeast, fruit fly, worm, mouse, and human. Five septin genes have been cloned and sequenced from the model filamentous fungus A. nidulans. As expected, the A. nidulans septins contain the highly conserved GTP binding and coiled-coil domains seen in other septins. On the basis of hybridization of clones to a chromosome-specific library and correlation with an A. nidulans physical map, the septins are not clustered but are scattered throughout the genome. In phylogenetic analysis most fungal septins could be grouped with one of the prototypical S. cerevisiae septins, Cdc3, Cdc10, Cdc11, and Cdc12. Intron-exon structure was conserved within septin classes. The results of this study suggest that most fungal septins belong to one of four orthologous classes.
