The complete nucleotide sequence was determined for genomic RNA of White clover mosaic virus (WCIMV-RC) isolated from red clover (Trifolium pratense) in Japan. It is 5843 nucleotides in length, excluding the poly(A) tail at the 3' terminus. Similar to other potexviruses, it contains five open reading frames (ORFs 1 through 5), which putatively encode an RNA-dependent RNA polymerase (RdRp) (147 kDa), a triple gene block (TGB) (26 kDa/13 kDa/7 kDa), and a coat protein (CP) (22 kDa), respectively. The deduced amino acid sequence of the WCIMV-RC CP was identical to that of WCIMV-O, one of two New Zealand isolates, but only 85% identical to that of WCIMV-M, the other New Zealand isolate, because of heterogeneity in the C-termini of CP amino acid sequences. The implication of this CP heterogeneity is discussed.
