The complete nucleotide sequence of the coat protein (CP) gene of Bermuda grass etched-line virus (BELV), including 376 nucleotides (nt) of the region to its 5' side, was determined and compared with sequences of the other viruses associated with the genus Marafivirus, substantiating the assignment of BELV to this group. The CP gene coding sequence was 585 nt in length. Inferred amino acid sequences showed homologies among marafiviral CP gene products ranging from 41% to 59%. A non-coding sequence motif characteristic of the marafiviruses lies in the region adjacent to the CP gene to the 5' side. In contrast to various homology levels in the coding regions of the CP genes, the interspecific sequence homology in this 18 nt motif was almost perfect.
测定了百慕大草蚀纹线病毒（BELV）外壳蛋白（CP）基因的完整核苷酸序列，包括其5'端区域的376个核苷酸（nt），并与马拉病毒属其他相关病毒的序列进行了比较，证实BELV属于该组。CP基因编码序列长度为585 nt。推导的氨基酸序列显示，马拉病毒CP基因产物之间的同源性在41%至59%之间。马拉病毒特有的非编码序列基序位于CP基因5'端相邻区域。与CP基因编码区的各种同源水平不同，这个18 nt基序中的种间序列同源性几乎是完美的。
