摘要：A review of reproduction in the myxomycetes reveals that they have a basic one-locus multiple-alleleic heterothallic mating system, which controls syngamy between haploid amoeboflagellates to produce the diploid plasmodium. However, each morphologically defined species contains a number of biological sibling species that can’t interbreed with each other and are centered in different regions of the world. Also, these morphospecies generally contain numerous non-heterothallic strains that can complete the life cycle from a single isolated spore. While there is information that suggests that some of these strains are homothallic, the majority of the evidence supports an apomictic system derived from a blockage of meiosis during spore formation. Thus, these non-heterothallic strains produce diploid amoeboflagellates that can develop directly into plasmodia without the need for crossing
