Determination of complete nucleotide sequence of Hibiscus latent Singapore virus: evidence for the presence of an internal poly(A) tract.
We have sequenced the complete genome of a hibiscus-infecting tobamovirus, Hibiscus latent Singapore virus (HLSV). The experimental host range of HLSV is similar to that of another distinct species of hibiscus infecting tobamovirus, Hibiscus latent Fort Pierce virus (HLFPV). The genomic structure of HLSV is similar to other tobamoviruses in general. It consists of a 5' untranslated region (UTR), followed by ORFs encoding for a 128 kDa protein and a 186 kDa readthrough protein, a 30 kDa movement protein (MP), 18 kDa coat protein (CP) and a 3' UTR. The unique feature of HLSV is the presence of a poly(A) tract within its 3' UTR. In our previous work, we have reported MP and CP sequences of HLSV and its phylogenetic analysis. Here we report the complete nucleotide sequence of HLSV, phylogenetic analysis of the nucleotide and amino acid sequences of 128/186 kDa ORFs and the presence of a uniquely located poly(A) tract within the 3' UTR.
