Complete genome sequence of a new virus, a tentative member of the family Geminiviridae, infecting hedge bindweed (Calystegia sepium) in South Korea
摘要
The family Convolvulaceae comprises approximately 50–60 genera with approximately 1600–1700 species, exhibiting a rich diversity of morphological characteristics and occupying a broad range of ecological habitats. High-throughput sequencing identified a tentative new virus in the family Geminiviridae infecting Calystegia sepium var. japonica in South Korea. The 2,706 nt long genome comprises six open reading frames (ORFs). The analysis of the nucleotide sequence of the genome and the putative amino acid sequences of ORFs indicated that the virus was closely related to the members of the family Geminiviridae. The genome organization of the virus was similar to that of members of the genus Topilevirus in terms of the number of ORFs and splicing signal. However, the virus, tentatively named bindweed mottle virus (BWMV), may not be assigned to current genera into the family Geminiviridae.
