Abstract

Despite the ecological significance of viral communities, phages remain insufficiently studied. Current genomic databases lack high-quality phage genome sequences linked to specific bacteria. Bacteria of the genus Erwinia are known to colonize the phyllosphere of plants, both as commensals and as pathogens. We isolated three Erwinia billingiae phages-Zoomie, Pecta, and Snitter-from organic household waste. Based on sequence similarity to their closest relatives, we propose that they represent three new genera: "Pectavirus" within the family Zobellviridae, "Snittervirus" in the subfamily Tempevirinae, family Drexlerviridae, and "Zoomievirus" within the family Autographiviridae, which, together with the genus Limelightvirus, may constitute a new subfamily.

摘要

尽管病毒群落具有生态意义，但噬菌体仍未得到充分研究。当前的基因组数据库缺乏与特定细菌相关的高质量噬菌体基因组序列。已知欧文氏菌属细菌可作为共生菌和病原体定殖于植物叶际。我们从有机生活垃圾中分离出了三种比氏欧文氏菌噬菌体——Zoomie、Pecta和Snitter。基于与它们最亲近亲属的序列相似性，我们提议将它们归为三个新属：佐贝尔病毒科中的“果胶病毒属”、德雷克斯勒病毒科Tempovirinae亚科中的“Snittervirus属”以及自显病毒科中的“Zoomievirus属”，这三个属与Limelightvirus属一起可能构成一个新亚科。
