Sequence analysis and genome organization of a new marafivirus from Leptochloa chinensis.

High-throughput sequencing was used to identify and characterize a novel marafivirus from the weed Leptochloa chinensis, which was tentatively named "Leptochloa chinensis marafivirus" (LcMV). The complete genome of the virus consists of 6,178 base pairs, and its nucleotide sequence is 73.82% identical to that of Sorghum almum marafivirus, which is a member of the genus Marafivirus within the family Tymoviridae.
