The complete nucleotide sequence and genome organization of soybean yellow mottle mosaic virus severe strain causing bright yellow mosaic, mottling and puckering symptoms in soybean (Glycine max) from India was determined. The monopartite single stranded genomic RNA is 3974 nuclotides long and has the potential to encode six viral proteins viz., p25, p83, p8, p10, p39 and p25. The SYMMV-Sb isolate differed from mungbean strain with 69 nucleotides and nine aminoacids dispersed over the various ORFs. Comparative sequence analysis revealed that SYMMV-Sb shared 98% nt sequence identity at complete genome level and 96–100% at all ORFs level with SYMMV mungbean strain from India and 71–92% identity with SYMMV Korean soybean isolate, whereas it showed very low sequence identity with other tombusviridae members (2–53%). The phylogenetic analysis showed the clustering of SYMMV-Sb along with other members of genus Gammacarmovirus. The SYMMV-Sb isolate produced chlorotic blotches, mild and veinal mottling, necrosis and puckering symptoms in various leguminous host plants. The symptomatalogy of the soybean isolate was differed from mungbean strain as earlier induced severe symptoms on soybean and mild symptoms on mungbean.

大豆黄色斑驳花叶病毒重株引起大豆亮黄色花叶、斑驳和起皱症状的完整核苷酸序列和基因组结构（ Glycine max）来自印度的决心。单部分单链基因组 RNA 长 3974 个核苷酸，有可能编码六种病毒蛋白，即 p25、p83、p8、p10、p39 和 p25。SYMMV-Sb 分离株与绿豆菌株不同，有 69 个核苷酸和 9 个氨基酸分散在不同的开放阅读框上。比较序列分析显示，SYMMV-Sb 在全基因组水平上具有 98% 的 nt 序列同一性，在所有 ORF 水平上与来自印度的 SYMMV 绿豆菌株具有 96-100% 的同一性，与 SYMMV 韩国大豆分离株具有 71-92% 的同一性，而它表现出非常低与其他毒蕈科成员的序列同一性（2-53%）。系统发育分析显示 SYMMV-Sb 与Gammacarmovirus属的其他成员聚集在一起. SYMMV-Sb 分离株在多种豆科寄主植物中产生褪绿斑点、轻度和叶脉斑点、坏死和起皱症状。大豆分离株的症状学与绿豆菌株不同，早期对大豆引起严重症状，对绿豆引起轻度症状。
