Abstract

Heterogeneity in polydnavirus DNA was exploited as a means of following the transmission of viral genomes in parasitoid populations. Parasitoid lines isogenic for viral DNA markers were established from both a braconid (Cotesia melanoscela) and an ichneumonid (Hyposoter fugitivus) species. In crossing experiments these markers routinely segregated in Mendelian (chromosomal) fashion, suggesting that the structure of polydnavirus genomes is probably determined by the integrated form of viral DNA, rather than by extrachromosomal molecules.

摘要

利用多DNA病毒DNA的异质性作为追踪病毒基因组在寄生蜂种群中传播的一种手段。从一种茧蜂（黑角侧沟茧蜂）和一种姬蜂（逃亡长尾姬蜂）物种中建立了对病毒DNA标记等基因的寄生蜂品系。在杂交实验中，这些标记通常以孟德尔（染色体）方式分离，这表明多DNA病毒基因组的结构可能由病毒DNA的整合形式决定，而不是由染色体外分子决定。
