Nucleotide sequence of segment S9 of the rice dwarf virus genome.

The complete nucleotide sequence of genome segment S9, which was reported as the ninth largest among the 12 genome segments of rice dwarf virus, was determined. The segment was 1,305 bp long and coded for a protein composed of 351 amino acids (Mr 38,930). The terminal sequences of the segment were found to consist of an imperfect 14 base pair inverted repeat located at positions 2-15 and 1289-1302, which is similar to that identified in other reoviruses.
