Molecular characterization of coat protein gene of Garlic common latent virus isolates from India: an evidence for distinct phylogeny and recombination
Virus Genes 47 (1), 189-193
Abstract: The coat protein (CP) gene of five Indian Garlic common latent virus (GarCLV) isolates was sequenced and it was 960 bp long in all the five isolates, encoding a protein of 319 amino acids. Comparative nucleotide sequence analysis revealed diversity of 4.3 % among the Indian isolates and of 11.9 % among all isolates worldwide. Amino acid sequence comparison showed a significant variability in the N-terminal of CP of GarCLV. Various protein analysis tools identified thirteen conserved domains and motifs including Carlavirus and Potexvirus-specific Flexi CP and Flexi N CP. Phylogenetic analysis clustered GarCLV isolates in the subgroup II with isolates from Australia, Brazil, Japan, and South Korea. Intraspecies recombination study revealed that only one of the Indian isolates was a recombinant. Interspecies recombination study suggested the absence of genetic exchange from Carlavirus species to GarCLV; conversely, GarCLV was identified as a putative donor for at least two other Carlavirus species. This is the first report of molecular variability and recombination in GarCLV isolates.
