核型多角体病毒基因组学研究进展

Progress in Nuclear Polyhedrosis Virus Genomics

昆虫病毒是专性侵染节肢动物的一类微生物,包括核型多角体病毒、颗粒体病毒、质型多角体病毒、痘病毒、虹彩病毒等很多类群。核型多角体病毒属于杆状病毒科(Rhabdoviridae)核型多角体病毒属(Nucleopolyhedrovirus),是昆虫病毒中最大的类群。它能够专一性地侵染并杀死一种或者几种农林害虫,并且对害虫天敌、环境、人畜无害,是一种值得推广的绿色生物农药。本文总结了获得全基因组序列的核型多角体病毒,综述了核型多角体病毒的基因组主要功能基因(RNA转录相关基因、DNA复制相关基因、结构相关基因)及其他基因,并对核型多角体病毒今后的发展方向进行了展望。

Insect viruses are the microbes infecting arthropods only, virus, cytoplasmic polyhedrosis virus, poxvirus, iridovirus belongs to Rhabdoviridae Nucleopolyhedrovirus, which is the including nuclear polyhedrosis virus, granulosis and many other groups. The nuclear polyhedrosis virus largest group of insect viruses. It can infect and kill one or several agricultural and forestry pests specifically, and is harmless to the natural enemies, environment, human and animals. So it is considered as the environment-friendly biopesticides to be worth promoting. This paper reviews recent research on the genomics of nuclear polyhedrosis virus, and summarizes the main functional genes including transcription related genes, DNA replication related genes, structure related genes and other genes. Further more, future development direction of the nuclear polyhedrosis virus is also prospected.
