First complete genome sequence of vanilla mosaic strain of Dasheen mosaic virus isolated from the Cook Islands.

Abstract

We present the first complete genome of vanilla mosaic virus (VanMV). The VanMV genomic structure is consistent with that of a potyvirus, containing a single open reading frame (ORF) encoding a polyprotein of 3139 amino acids. Motif analyses indicate the polyprotein can be cleaved into the expected ten individual proteins; other recognised potyvirus motifs are also present. As expected, the VanMV genome shows high sequence similarity to the published Dasheen mosaic virus (DsMV) genome sequences; comparisons with DsMV continue to support VanMV as a vanilla infecting strain of DsMV. Phylogenetic analyses indicate that VanMV and DsMV share a common ancestor, with VanMV having the closest relationship with DsMV strains from the South Pacific.

Occurrence and characterization of viruses infecting Amorphophallus in Yunnan, China

“…S1 ). These results suggest that Albus-sym is distinct from other DsMV isolates as well as the VanMV strain, whose complete genome is 75.8–77.1% and 83.9–86.7% identical to DsMV at the nt and aa levels, respectively 17 .…”

“…The Amorphophallus isolates in this study shared the highest nt identity (97.87%) with the JH taro isolate (Acc.no. AFA28134), followed (97.57%) by YN80 isolate 17 from China. Except for Albus-sym and Konjac-98, the CP size (321aa–329aa) of DsMV Amorphophallus isolates from China was bigger than some isolates such as BF1, BF8, BF39 and _Pinellia_Yunnan isolate.…”
