南部的米饭黑条纹的矮子病毒(SRBSDV ) 是在米饭在流行的新奇 Fijivirus 南部并且华中，和北越南。它的染色体把双 stranded RNA 的 10 个片断根据他们的尺寸命名 S1 到 S10。一 SRBSDV 的 isolate， JNi4，从 Jining 从自然地感染的玉米工厂被获得，山东省，在 2008 玉米季节。SRBSDV 的有那些的到分别地，与瑞斯的相应片断，黑条纹的矮子病毒孤立的 72.6%73.1% ， 72.3%73% ， 73.9%74.5% 和 77.3%79% 的 JNi4 份额核苷酸身份的 S10 的片断 S7，和 99.7% 的身份， 99.1%99.7% ， 98.9%99.5% ，和 98.6%99.2% 孤立 HN 和 GD。JNi4 在与 S7 的 genomic 序列构造到 S10 的种系发生的树上与 GD 和 HN 形成一根分开的树枝。这些结果作为类 Fijivirus 的不同的种证实 SRBSDV 的建议分类地位并且显示 JNi4 是一 SRBSDV 的 isolate。山东是到目前为止 SRBSDV 在中国被发现的极北的区域。

英文摘要：

Southern rice black-streaked dwarf virus （SRBSDV） is a novel Fijivirus prevalent in rice in southern and central China,and northern Vietnam. Its genome has 10 segments of double-stranded RNA named S1 to S10 according to their size. An isolate of SRBSDV,JNi4,was obtained from naturally infected maize plants from Ji＇ning,Shandong province,in the 2008 maize season. Segments S7 to S10 of JNi4 share nucleotide identities of 72.6%-73.1%,72.3%-73%,73.9%-74.5% and 77.3%-79%,respectively,with corresponding segments of Rice black-streaked dwarf virus isolates,and identities of 99.7%,99.1%-99.7%,98.9%-99.5%,and 98.6%-99.2% with those of SRBSDV isolates HN and GD. JNi4 forms a separate branch with GD and HN in the phylogenetic trees constructed with genomic sequences of S7 to S10. These results confirm the proposed taxonomic status of SRBSDV as a distinct species of the genus Fijivirus and indicate that JNi4 is an isolate of SRBSDV. Shandong is so far the northernmost region where SRBSDV is found in China.
