title: Sequencing and analysis for the full-length genome RNA of foot-and-mouth disease virus China/99.
abstract: The complete nucleotide sequence of genomic RNA of foot and mouth disease virus (FMDV) strain China/99 from infected bovine tongue epithelium is presented. The nucleotide sequence extending from the 5' end of the genomic RNA to the 5' end of poly (A) tail contains 8173 nucleotides (nt). Its open reading frame, which encodes a single polypeptide of 2332 amino acids, encompasses 6999 nt starting from the initiation codon AUG and terminating at the UAA codon 93 bases upstream from the 5' end of poly (A) tract. The 5' untranslated region (UTR) is composed of 1081 nt. The consensus of the 1d gene of FMDV strain China/99 compared with that of UKG/6/2001, UKG/12/2001, China/99HN4 and China/3/Tibet is over 97%. The result showed the stains belong to the members of the Pan-Asia family. There is a remarkable differentiation in the function-unknown (FUR), p2 and p3 regions between FMDV isolates from infected cattle and swine, especially in 3a gene. No deletion was found in genes I, 1a, 1b, 2a, 2c, 3b, and 3d. These genes might be indispensable to the surviving of FMDV. The secondary structures of small (S) fragments, FUR and an internal ribosome entry site can be classified into three types, and the S fragment and 3' UTR of the positive-sense RNA fold into stem-loop structures similar to the shape of clover.
