A cytological comparison has been made of representative isolates of johnsongrass mosaic (JGMV), maize dwarf mosaic (MDMV), sorghum mosaic (SrMV) and sugarcane mosaic (SCMV) viruses. These four viruses now encompass the complex of virus strains which were formerly considered as strains of sugarcane mosaic and/or maize dwarf mosaic viruses. The structure of the cytoplasmic cylindrical inclusions induced by these viruses, together with other cytological alterations, allow the four viruses to be distinguished. Pinwheels, scrolls and laminated aggregates were produced only by SCMV whereas JGMV, MDMV, and SrMV produced only pinwheels and scrolls. SrMV produced amorphous cytoplasmic inclusions which are not produced by JGMV and MDMV. The latter two were rather similar in cytological effects except that the SCMV-JG (U.S.A.) isolate of MDMV produced aggregates of needle-like structures in the cytoplasm which were not found with JGMV and the other MDMV isolates. The specific cytological effects induced by these viruses thus corroborate the recent classification of these viruses based mainly on the properties of the coat-protein gene, the 3' noncoding nucleotide sequences, and host reactions.
对约翰逊草花叶病毒（JGMV）、玉米矮花叶病毒（MDMV）、高粱花叶病毒（SrMV）和甘蔗花叶病毒（SCMV）的代表性分离株进行了细胞学比较。这四种病毒现在涵盖了以前被认为是甘蔗花叶病毒和/或玉米矮花叶病毒株系的病毒株复合体。这些病毒诱导产生的细胞质柱状内含体的结构，以及其他细胞学变化，使得这四种病毒得以区分。风车状、卷曲状和层状聚集体仅由SCMV产生，而JGMV、MDMV和SrMV仅产生风车状和卷曲状。SrMV产生无定形细胞质内含体，而JGMV和MDMV不产生。后两者在细胞学效应上相当相似，只是MDMV的SCMV-JG（美国）分离株在细胞质中产生了针状结构聚集体，而JGMV和其他MDMV分离株未发现这种结构。因此，这些病毒诱导产生的特定细胞学效应证实了最近主要基于外壳蛋白基因特性、3'非编码核苷酸序列和宿主反应对这些病毒进行的分类。
