Abstract

Cytoplasmic incompatibility results in embryo mortality in diploids, or all male offspring in haplodiploids, when individuals carrying different cytoplasmic factors are crossed. Cytoplasmic factors have been identified as intracellular micro-organisms. Microbe-induced cytoplasmic incompatibility is found in many insect taxa and may play a role in reproductive isolation between populations. Such micro-organisms cause bidirectional incompatibility between species of the parasitoid wasp genus Nasonia. The phylogenetic relationship of cytoplasmic incompatibility microorganisms (CIM) of different Nasonia species was analysed using their 16S ribosomal DNA (rDNA) sequence. Two 16S rDNA operons were detected in the CIM of each Nasonia species. Sequence analysis indicates that the Nasonia CIM are closely related and belong to the alpha group of the Proteobacteria.

摘要

当携带不同细胞质因子的个体杂交时，细胞质不亲和会导致二倍体胚胎死亡，或在单双倍体中产生全为雄性的后代。细胞质因子已被鉴定为细胞内微生物。微生物诱导的细胞质不亲和在许多昆虫类群中都有发现，并且可能在种群间的生殖隔离中起作用。这种微生物在寄生蜂丽蝇蛹集金小蜂属的不同物种之间引起双向不亲和。利用不同丽蝇蛹集金小蜂物种的细胞质不亲和微生物（CIM）的16S核糖体DNA（rDNA）序列分析了它们的系统发育关系。在每个丽蝇蛹集金小蜂物种的CIM中检测到两个16S rDNA操纵子。序列分析表明，丽蝇蛹集金小蜂的CIM密切相关，属于变形菌门的α亚群。
