The nucleotide sequence of the genomic RNA of kennedya yellow mosaic tymovirus-Jervis Bay isolate (KYMV-JB) has been determined. The genome of KYMV-JB is 6362 nucleotide residues long and encodes three major open reading frames. The genomic organization and the encoded proteins of KYMV-JB are very similar to those of three other tymoviruses that have recently been reported. Sequence comparisons revealed that the possible replicase proteins of tymoviruses are closely related to those of potexviruses and carlaviruses, suggesting a close evolutionary relationship among these viruses, despite differences in their genome organization and particle morphology.
已测定了肯尼迪亚黄花叶芜菁黄花叶病毒杰维斯湾分离株（KYMV-JB）基因组RNA的核苷酸序列。KYMV-JB的基因组长度为6362个核苷酸残基，编码三个主要的开放阅读框。KYMV-JB的基因组结构和编码的蛋白质与最近报道的其他三种芜菁黄花叶病毒非常相似。序列比较显示，芜菁黄花叶病毒的可能复制酶蛋白与马铃薯X病毒属病毒和香石竹潜隐病毒属病毒的复制酶蛋白密切相关，这表明尽管这些病毒在基因组结构和颗粒形态上存在差异，但它们之间存在密切的进化关系。
