自从发现第一个“巨型病毒”以来,人们特别关注通过棘阿米巴属分离和培养这些大型 DNA 病毒。诱饵系统。虽然这种方法可以在核细胞病毒门中发现大量新型病毒,但基于环境组学的分析表明,该门之间存在丰富的多样性,特别是在海洋数据集中。这些病毒在元转录组中的流行表明它们在海洋营养物质周转中的生态重要性,因此,对非变形虫核细胞病毒的深入研究应被视为病毒生态学的焦点。在这篇综述中,我们报告了奎托斯病毒 Quantuckense(née Aureococcus anophagefferens 病毒),这是一种限制性病毒目藻类感染病毒。当前用于核细胞病毒门的研究系统与该病毒及其亲属有显着不同,并且与这些其他病毒相比,在生理学、编码潜力和生态学方面的一系列权衡揭示了 K. Quantuckense 的重要性。在此,我们回顾了对该病毒进行的研究及其作为藻类-病毒相互作用模型系统的潜力。
Since the discovery of the first “giant virus,” particular attention has been paid toward isolating and culturing these large DNA viruses through Acanthamoeba spp. bait systems. While this method has allowed for the discovery of plenty novel viruses in the Nucleocytoviricota, environmental -omics-based analyses have shown that there is a wealth of diversity among this phylum, particularly in marine datasets. The prevalence of these viruses in metatranscriptomes points toward their ecological importance in nutrient turnover in our oceans and as such, in depth study into non-amoebal Nucleocytoviricota should be considered a focal point in viral ecology. In this review, we report on Kratosvirus quantuckense (née Aureococcus anophagefferens Virus), an algae-infecting virus of the Imitervirales. Current systems for study in the Nucleocytoviricota differ significantly from this virus and its relatives, and a litany of trade-offs within physiology, coding potential, and ecology compared to these other viruses reveal the importance of K. quantuckense. Herein, we review the research that has been performed on this virus as well as its potential as a model system for algal-virus interactions.
