The 5'- and 3'-terminal nucleotide sequences of the dsRNA genome segments of rice ragged stunt virus (RRSV), a member of the plant Reoviridae, were determined and compared with those published for other viruses in this family. The 5'- and 3'-terminal regions of the RRSV plus strand RNA from all genome segments were found to have the same conserved hexanucleotide (5' GAUAAA---) and tetranucleotide (---GUGC 3') sequences, respectively. These conserved terminal sequences were different from those found in viruses in the Phytoreovirus and Fijivirus genera. This result confirms that, as already suggested, RRSV should be placed in a third genus.
水稻锯齿叶矮缩病毒（RRSV）是植物呼肠孤病毒科的成员之一，其双链RNA基因组片段的5'端和3'端核苷酸序列已被测定，并与该科其他病毒已发表的序列进行了比较。发现来自所有基因组片段的RRSV正链RNA的5'端和3'端区域分别具有相同的保守六核苷酸（5' GAUAAA---）和四核苷酸（---GUGC 3'）序列。这些保守的末端序列与植物呼肠孤病毒属和斐济病毒属病毒中的序列不同。这一结果证实，正如之前所建议的，RRSV应归为第三个属。
