Abstract

The 5' and 3' terminal sequences of the plus strand of Fiji disease fijivirus (FDV) segments 2, 3, 9 and 10 possess the conserved terminal sequences, 5'AAGUUUUU.....CAGCAGAUGUC 3'. The 5' sequence is identical to that of maize rough dwarf fijivirus (MRDV) and rice black-streaked dwarf fijivirus (RBSDV), whereas the FDV 3' sequence shares the consensus, CAGCNNNNGUC, with MRDV and RBSDV. The FDV terminal sequences, and the amino acid sequences from FDV segment 9, are more closely related to those from MRDV and RBSDV than to those from oat sterile dwarf fijivirus (OSDV) and Nilaparvata lugens reovirus (NLRV; a putative Fijivirus).

摘要

斐济病斐济病毒（FDV）第2、3、9和10片段正链的5'和3'末端序列具有保守的末端序列，即5'AAGUUUUU.....CAGCAGAUGUC 3'。5'序列与玉米粗缩斐济病毒（MRDV）和水稻黑条矮缩斐济病毒（RBSDV）的相同，而FDV的3'序列与MRDV和RBSDV共有一致序列CAGCNNNNGUC。与燕麦不育矮缩斐济病毒（OSDV）和褐飞虱呼肠孤病毒（NLRV；一种假定的斐济病毒）相比，FDV末端序列以及FDV第9片段的氨基酸序列与MRDV和RBSDV的更为相近。
