Variability in the length of the amino terminal sequence contributes to the capsid protein diversity among dasheen mosaic potyvirus isolates.
Western blot analysis of several dasheen mosaic virus isolates revealed molecular weight differences among their capsid proteins (CPs). Sequence analysis of the CP gene showed that the CP of isolate TEN was 15 amino acids shorter than that of isolate LA due to a 57-base deletion and a 12-base insertion into the 5' end of the TEN CP gene. Our data suggest that frequent deletions and insertions are responsible for the CP size diversity among DMV isolates.
