By pairing of strains of Dictyostelium giganteum in various combinations this species was shown to be heterothallic. Four mating types were identified. Some strains could not be assigned a mating type and others showed no mating reaction. No self-compatible strains were found. Mutations were introduced in several strains and genetic crosses were performed. The results of these crosses show that mating and macrocyst formation are controlled by a single locus-multiple allele incompatibility system. The results also support the view that the myxamoebae that emerge upon germination of the macrocysts are the products of meiosis.
通过将巨大盘基网柄菌的菌株以各种组合方式配对,表明该物种是异宗配合的。鉴定出了四种交配型。一些菌株无法被指定交配型,而其他菌株则没有交配反应。未发现自交亲和的菌株。在几个菌株中引入了突变并进行了遗传杂交。这些杂交的结果表明,交配和大囊泡形成受单一位点-多等位基因不相容系统控制。结果还支持这样一种观点,即大囊泡萌发时出现的黏变形体是减数分裂的产物。
