The sequence is presented of RNA-4 of Echinochloa hoja blanca tenuivirus (EHBV), one of two tenuiviruses associated with rice cultivation in Latin America (together with rice hoja blanca virus; RHBV). Analysis of the sequence shows that the coding regions of EHBV RNA-4 are closely related to those of RHBV RNA-4. However, the intergenic region separating the two ambisense open reading frames, are highly distinct for the two viruses. The features of the RNA and the comparisons with the sequences of RNA-4 of RHBV, rice stripe virus (RStV) and maize stripe virus (MStV) are discussed.
本文展示了拉丁美洲与水稻种植相关的两种纤细病毒之一——白叶稗纤细病毒（EHBV）的RNA - 4序列（另一种是水稻白叶病毒；RHBV）。序列分析表明，EHBV RNA - 4的编码区与RHBV RNA - 4的编码区密切相关。然而，分隔两个双义开放阅读框的基因间隔区，在这两种病毒中却高度不同。文中讨论了该RNA的特征以及与RHBV、水稻条纹病毒（RStV）和玉米条纹病毒（MStV）的RNA - 4序列的比较。
