Popis: | The RNA genome of an Indian strain of Japanese encephalitis virus (JEV), GP78, was reverse transcribed and the cDNA fragments were cloned in bacterial plasmids. Nucleotide sequencing of the cDNA clones covering the entire genome of the virus established that the GP78 genome was 10,976 nucleotides long. An open reading frame of 10,296 bases, capable of coding for a 3,432 amino acid polyprotein, was flanked by 95- and 585-base long 5'- and 3'-non-coding regions, respectively. When compared with the nucleotide sequence of the JaOArS982 strain, the JEV GP78 genome had a number of nucleotide substitutions that were scattered throughout the genome except for the 5'-noncoding region, the sequence of which was fully conserved. Comparison of the complete genome sequences of different JEV isolates showed a 1.3-4.1% nucleotide sequence divergence among them, which resulted in 0.6-1.8% amino acid sequence divergence. Analysis based on the complete genome sequences of different JEV isolates showed that the GP78 isolate from India was phylogenetically closer to the Chinese SA14 isolate. |
