Synonymous substitutions disrupting base pairs C576-G531 and C534-G573 did not affect viral accumulation. After three serial passage inoculation, the accumulation of spontaneous mutant viruses was restored and codons A532G533A534, A532G533G534, a574g575a576, or a574g575g576 of mutants was separately changed to C532G533A534, C532G533G534, C574g575a576, or C574g575g576. Synonymous mutation of R178 and R192 also reduced viral accumulation in N. tabacum plants. Therefore, we concluded that the two consecutive c532-g575 and
