摘要: A novel varicosa-like virus was identified in a tall morning glory (Ipomoea purpurea) plant by high-throughput sequencing and tentatively named "morning glory varicosavirus" (MGVV). The complete genome of MGVV contains two segments of negative-sense single-stranded RNA of 6409 (RNA1) and 5288 (RNA2) nucleotides. RNA1 encodes a 224.3-kDa large protein (224K), and RNA2 encodes four putative proteins of 48.6 kDa (49K), 46.4 kDa (46K), 35.7 kDa (36K), and 36.8 kDa (37K), respectively. The 224K and 49K proteins show amino acid sequence similarity to the large protein (39.4%) and the 49K protein (22.6%), respectively, of red clover-associated varicosavirus, and the 36K protein shares 19.6% amino acid sequence similarity with protein 3 of lettuce big-vein associated virus. The 46K and 37K proteins share no significant sequence similarity to known functional viral sequences. Phylogenetic analysis based on the large protein of MGVV and other rhabdoviruses showed that MGVV clustered with the varicosaviruses. These analyses indicate that MGVV is a novel member of the genus Varicosavirus in the family Rhabdoviridae.
