Abstract

Polydnaviruses, obligatorily associated with endoparasitoid wasps, are unique in that their segmented genome is composed of multiple double-stranded DNA circles. We present here the first cytological evidence that virus segments are integrated in the wasp genome, obtained by using in situ hybridization of virus probes with viral sequences in the chromosomes of a wasp from the braconid family of hymenopterans.

摘要

多分DNA病毒与内寄生蜂必然相关,其独特之处在于其分段基因组由多个双链DNA环组成。我们在此展示了首个细胞学证据,即通过使用病毒探针与膜翅目茧蜂科一种黄蜂染色体中的病毒序列进行原位杂交,发现病毒片段整合到了黄蜂基因组中。
