摘要: 噬菌体作为结构最简单的生命体,不仅在调节寄主群落结构、遗传物质的水平移动方面作用巨大,同时也被证明在元素生物地球化学循环中具有非常重要的地位。尽管噬菌体的重要性越来越引起研究者的关注,但遗憾的是目前对于噬菌体基因多样性的研究还存在很大的局限性,发现并验证一种适合于研究噬菌体基因多样性的分子标记基因是环境病毒生态学研究的热点之一。介绍了一种新的分子标记基因-噬菌体辅助代谢磷酸盐调节基因phoH,并综述了近年来利用该基因揭示海洋海水、稻田田面水和沙漠石下生物中噬菌体基因多样性的研究进展。结果表明,噬菌体phoH基因分布与其生存环境关系密切,按获取环境不同phoH基因被划分为多个类群。最后对噬菌体phoH基因未来研究方向给予展望。

Abstract: Bacteriophages(phages)are the simplest biological entities,which play important roles not only in the regulation of their host communities and horizontal transfer of genetic materials,but also in the element biogeochemical cycles. Although the importance of phages is increasingly being paid attentions by researchers,however there are still great limitations on the study of phage gene diversity until now. Therefore,the work of finding and verification of a suitable molecular marker gene for studying the genetic diversity of phage in natural environments is one of the hotspots of virus ecology. In this paper,a new molecular biomarker gene of phage auxiliary metabolic gene of phoH was introduced,and the recent advances in using this gene to reveal the phage genetic diversity in marine waters,paddy floodwaters and desert hypoliths are reviewed. Results showed that the distribution of phage phoH gene was closely related to its living environments,and phoH clones were divided into several groups according their obtained environments. In the end of the paper,the future research directions of phage phoH gene are also proposed.
