The genome of cassava common mosaic potexvirus (CsCMV) has been sequenced from cDNA clones and consists of 6376 nucleotides (nt). A 76 nt untranslated region (UTR) at the 5? terminus was followed by ORF1 which potentially encodes a protein of 1449 amino acids (aa). ORFs 2, 3, and 4 were predicted...

Cassava Frogskin Disease (CFSD) can cause severe damage to cassava roots and is one of the most important diseases of cassava in Latin America. The principal objective of this study was to identify the causal agent of CFSD. Electron microscopy, viral purifications, double-stranded RNA (dsRNA) ana...
