【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pho H,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pho H基因分布与其生存环境关系密切,按获取环境不同pho H基因被划分为多个类群。最后对噬菌体pho H基因未来研究方向给予展望。
[Abstract]:Bacteriophage, as the simplest organism with the simplest structure, not only plays an important role in regulating the host community structure and the horizontal movement of genetic material, but also proves to play a very important role in the biogeochemical cycle of elements. Although the importance of bacteriophage has attracted more and more attention, it is a pity that there are still great limitations in the study of bacteriophage gene diversity. It is found and verified that a molecular marker gene suitable for the study of bacteriophage gene diversity is one of the hotspots in environmental virus ecology. In this paper, a new molecular marker gene, bacteriophage assisted metabolic phosphate regulatory gene pho H, was introduced, and the research progress of using this gene to reveal the diversity of bacteriophage genes in marine seawater, surface water of paddy field and desert rock in recent years was reviewed. The results showed that the distribution of bacteriophage pho H gene was closely related to its living environment, and the pho H gene was divided into many groups according to the different acquisition environment. Finally, the future research direction of bacteriophage pho H gene is prospected.
