Abstract

Polydnavirus is a mutualistic DNA virus found in some braconid and ichneumonid wasps. Its genome is integrated into host chromosome as a provirus. Its replication occurs at ovarian calyx epithelium during host pupal stage to form episomal viral particles. The viral particles are delivered into hemocoel of the parasitized insect along with eggs during wasp oviposition. Several polydnaviral genomes, which are isolated from the episomal virus particles, have been sequenced and exhibit some gene families with speculative physiological functions. This review presents the viral characteristics in terms of Its parasitic physiology. For developing new insect pest control tactics, it also discusses several application strategies exploiting the viral genome to manipulate insect physiology.

폴리드나바이러스는 고치벌 및 맵시벌류에 공생하는 DNA 바이러스로 기주 염색체에 프로바이러스 형태로 존재한다. 이 바이러스의 복제는 기주 용발육시기에 난소받침 상피세포에서 시작되어 유리 바이러스 형태의 입자 구조를 이루게 된다. 바이러스 입자는 기주가 피기생체에 산란할 때 알과 함께 혈강으로 옮겨진다. 이 바이러스 게놈의 염기서열을 바탕으로 여러 폴리드나바이러스 유전자군이 동정되었으며, 이들의 생리적 기능도 알려지고 있다. 본 종설은 기생 생리적 견지에서 폴리드나바이러스 게놈을 특성화하고, 이를 토대로 생리 교란 유전자들을 응용할 수 있는 새로운 해충 방제 전략을 소개한다.
