前噬菌体

Prophages

摘要:

随着微生物基因组测序工作的广泛展开, 前噬菌体在宿主菌基因组中普遍存在的事实已逐渐为人们所接受。相关研究工作的深入揭示前噬菌体并不只是细菌体内一个简单的寄生体, 相反是细菌生理活动相当活跃的参与者, 在宿主菌生命活动中发挥着重要的作用。对前噬菌体的深入了解将丰富人们对多种生命现象的认识。本文即是关于前噬菌体的分类、分布、鉴定、进化及其与宿主菌相互作用等知识点的一个简单综述。

Abstract:

It is common in bacterial genomes of the integration of prophages. As an important participant of the vital movement of their hosts, prophages affect closely the biological properties of the hosts. Therefore, if we want to comprehend a bacterial genome fully, it is essential to recognize and understand accurately prophages in it. This article is a compendious review about the classification, distribution, identification, evolution of prophages and the interaction with their hosts.
