Cucumber mosaic virus (CMV) and brome mosaic virus (BMV) are isometric plant viruses. Although biologically distinct, they share many common chemical properties. An analysis of the partial genomic RNA sequence available for these two viruses reveals that they are evolutionarily related. Different segments of the genome exhibit different evolutionary rates. The coat proteins, which serve as carriers of genetic material, possess little or no homology. In contrast, the 3a proteins show over 35% homology. The non-coding regions of the genome also exhibit extensive but variable homology suggesting the functional importance of the nucleic acid.
黄瓜花叶病毒（CMV）和雀麦花叶病毒（BMV）是等轴对称的植物病毒。尽管它们在生物学上有区别，但具有许多共同的化学特性。对这两种病毒可用的部分基因组RNA序列分析表明，它们在进化上相关。基因组的不同片段表现出不同的进化速率。作为遗传物质载体的外壳蛋白几乎没有同源性。相比之下，3a蛋白显示出超过35%的同源性。基因组的非编码区也表现出广泛但可变的同源性，这表明核酸具有功能重要性。
