“…Codon usage patterns of viruses reflect evolutionary changes, such as adaption, evolution, evasion from host immune systems, and survival [ 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. Now, only limited reports show the codon usage patterns of plant viruses, such as citrus tristeza virus (CTV) [ 50 ], rice strape virus (RSV) [ 51 ], papaya ringspot virus (PRSV) [ 52 ], potato virus M (PVM) [ 53 ], sugarcane mosaic virus (SCMV) [ 54 ], broad bean wilt virus 2 (BBWV2) [ 55 ], rice black-streaked dwarf virus (RBSDV) [ 56 ], narcissus degeneration virus (NDV) [ 57 ], narcissus late season yellows virus (NLSYV) [ 57 ], and narcissus yellow stripe virus (NYSV) [ 57 ].…”
