Dasheen mosaic virus (DsMV) the main causative agent of mosaic
disease in elephant foot yam (Amorphophallus paeoniifolius) belongs
to Potyviridae. The complete genome sequence of DsMV infecting
A. paeoniifolius in Kerala state, India was assembled from the whole
transcriptome sequencing reads of diseased host samples. The sequence
of the virus which showed 83% identity with DsMV infecting Zantedeschia
aethiopica (China) was confirmed through amplification and sequencing
with primers designed based on the assembled sequence. Unambiguous
recombination events mainly confined to the 5′terminal 4000 nucleotides
of the genome with phylogenetically related potyviruses were recognized.
The length and genome composition towards the 3′ end comprising NIb,
CP and 3′ UTR were not dependent on the host or the source region.
