【 摘 要 】

References(34)Cited-By(4)Recognition of mating partners is of central importance in the sexual processes. In consideration that the most important function of sexuality is to shuffle genetic materials to generate wider variation of characters, mating among different genetic backgrounds is preferable. Wild isolates of cellular slime mold Dictyostelium discoideum are predominantly heterothallic, but homothallic ones also exist. In addition, there are bisexual strains which are compatible with either mating type of heterothallic strains but are self-incompatible. How cells of these organisms choose proper mating partners may include the essential mechanisms for sexual cell recognition in general. This minireview addresses studies on sexual cell interactions of D. discoideum with special attention to cell recognition and evolution of the mating system.
