主　　题：Rice stripe virus Genetic variability Genetic evolution 

摘      要：Rice stripe virus(RSV) is the type member of the genus *** is known to have four segmented,single-stranded RNA molecules and causes rice stripe disease in the rice fields of China,Japan,and *** on the complete genomic sequences of the determined 6 RSV isolates(from Yunnan,Jiangsu,Zhejiang,and Liaoning Provinces,China) and 27 other RSV isolates(from Yunnan,Jiangsu,Anhui,Henan,and Shandong Provinces of China,also Japan and Korea) downloaded from GenBank,we provided a genotyping profile of RSV field isolates and described the population structure of *** RSV isolates,except isolate CX,could be divided into two subtypes,one including 6 isolates from Yunnan Province,and the other including 26 isolates from different parts of China,Japan,and Korea,which were referred to as subtype II and subtype I,*** amino acid distances between subtypes range from 0.053 to *** isolates in Yunnan Province were genetically differentiated from other parts of China,Japan,and Korea and showed infrequent gene *** RSV populations collected from other parts of China,Japan,and Korea were only composed of subtype I and showed very low genetic *** speculated that isolate CX may be the result of recombination of isolates from two *** potential recombination events were detected in RNA4 of isolate CX.
