Abstract

Through high-throughput RNA sequencing, we discovered a putative new cytorhabdovirus in the seeds of Rudbeckia sp., which we have tentatively named "rudbeckia virus 1" (RudV1). Its complete 12,502-nt genomic sequence contains five open reading frames (ORFs): ORF1 (putative nucleocapsid protein, N), ORF2 (putative phosphoprotein, P), ORF3 (putative cell-to-cell movement protein, P3), ORF4 (putative matrix protein, M), and ORF5 (putative RNA-dependent RNA polymerase, L). BLASTp searches showed that ORF1, ORF3, ORF4, and ORF5 of RudV1 are most closely related to the corresponding proteins of Tagetes erecta virus 1 (a putative member of the genus Cytorhabdovirus) with 33.87% (88% query coverage), 55.98% (89% query coverage), 35.33% (94% query coverage), and 57.75% (98% query coverage) sequence identity at the amino acid level, respectively. Phylogenetic analysis and pairwise comparisons indicated that RudV1 is a novel member of the genus Cytorhabdovirus within the family Rhabdoviridae.
