Cassava (Manihot esculenta) is a staple crop in sub-Saharan Africa threatened by several viral diseases. Here, we describe the genome sequence of a novel bipartite cheravirus (family Secoviridae) infecting cassava in the Democratic Republic of Congo and Tanzania. We designate the new virus "cassava Congo cheravirus". Each RNA segment encodes a single polyprotein (P1 and P2 for RNA1 and RNA2, respectively), embedded with various putative cleavage sites (six and three in P1 and P2, respectively), consistent with members of the genus Cheravirus.
