In mycetomes of leafhoppers, Helochara communis, ultrastructural and histochemical studies revealed that spheroplast symbiotes (t-symbiotes) were converted to 'a-symbiotes' (so-called), with apparent loss of DNA--a phenomenon reminiscent of rhizobium-bacteroid conversion in certain legume nodules. Additional t-symbiotes were incorporated into the substance of these 'a-symbiotes'.
在叶蝉Helochara communis的菌胞中，超微结构和组织化学研究表明，球状体共生体（t-共生体）转变为“a-共生体”（所谓的），DNA明显丢失——这一现象让人联想到某些豆科植物根瘤中的根瘤菌-类菌体转变。另外的t-共生体被整合到这些“a-共生体”的物质中。
