Here, we describe the isolation and characterization of two novel phages from Brazilian soil that infect Ralstonia solanacearum and Ralstonia pseudosolanacearum, which we have named "RS phage AB1 and RS phage CA1. Genome sequencing and phylogenetic analysis revealed that RS phage AB1 is a novel member of the family Peduoviridae, while RS phage CA1 could not be classified as part of any established family. Thus, we propose a new viral family, "Anamaviridae", with two subfamilies, "Kantovirinae" and "Mascarenevirinae", with the latter including RS phage CA1. We propose the species names "Cocadavirus alagoinhas" and "Acarajevirus bahia" for RS phage CA1 and RS phage AB1, respectively. These findings increase our understanding of the diversity of phages infecting plant pathogens of the genus Ralstonia.
在此,我们描述了从巴西土壤中分离并鉴定出的两种新型噬菌体,它们可感染青枯雷尔氏菌和假青枯雷尔氏菌,我们将其命名为“RS噬菌体AB1”和“RS噬菌体CA1”。基因组测序和系统发育分析表明,RS噬菌体AB1是短尾病毒科的一个新成员,而RS噬菌体CA1不能归类于任何已确立的病毒科。因此,我们提出了一个新的病毒科“阿纳马病毒科”,包含两个亚科,即“坎托病毒亚科”和“马斯卡雷纳病毒亚科”,后者包括RS噬菌体CA1。我们分别为RS噬菌体CA1和RS噬菌体AB1提出了种名“阿拉戈伊尼亚斯椰子病毒”和“巴伊亚阿卡拉热病毒”。这些发现增进了我们对感染雷尔氏菌属植物病原体的噬菌体多样性的理解。
