A novel tobamovirus, brugmansia latent virus (BrLV), was discovered during a study of brugmansia (Brugmansia spp.) in the living collections held at the Royal Botanic Gardens, Kew. Here, we report the complete genome sequence of BrLV, which is 6,397 nucleotides long and contains the four open reading frames (RNA-dependent RNA polymerase, methyltransferase/helicase, movement, and coat proteins) typical of tobamoviruses. The complete genome sequence of BrLV shares 69.7% nucleotide sequence identity with brugmansia mild mottle virus (BrMMV) and 66.7 to 68.7% identity with other tobamoviruses naturally infecting members of the Solanaceae plant family. Phylogenetic analysis of the complete genome nucleotide sequence and the deduced amino acid sequences of the four tobamovirus proteins place BrLV in a subcluster with BrMMV within the Solanaceae-infecting tobamovirus subgroup as a new species.

在对布鲁格曼氏菌的研究中发现了一种新型的烟草花叶病毒，布鲁格曼氏潜伏病毒（BrLV）。spp。）在基尤皇家植物园举行的活动收藏中。在这里，我们报告了BrLV的完整基因组序列，该序列长6,397个核苷酸，并包含典型的烟草花叶病毒的四个开放阅读框（RNA依赖性RNA聚合酶，甲基转移酶/解旋酶，运动和外壳蛋白）。BrLV的完整基因组序列与布鲁格曼轻度斑驳病毒（BrMMV）具有69.7％的核苷酸序列同一性，与自然感染茄科植物家族成员的其他烟草花叶病毒具有66.7％至68.7％的同一性。对四种烟草花叶病毒蛋白的完整基因组核苷酸序列和推导的氨基酸序列进行系统进化分析，将BrLV置于感染茄科的烟草花叶病毒亚组的新物种BrMMV的亚群中。
