Research Abstract

The genome and cDNA analyses were performed in Acytostelium subglobosum, a cellular slime mold species without stalk-cell differentiation, and approximately 13,000 genes were identified. They included orthologues for most of the cell-differentiation related genes in Dictyostelium discoideum, the most widely used species with cell-differentiation abilities. However, closer examination of multi-gene families revealed that the family compositions were dissimilar between the two species.
