The genomes of Spanish isolates of Maize dwarf mosaic virus (MDMV-Sp) and Sugarcane mosaic virus (SCMV-Sp) were completely sequenced. Nucleotide sequence identities of SCMV-Sp to those of other SCMV isolates ranged from 79 to 90%. MDMV-Sp shared 85% nucleotide identity with the only other fully sequenced isolate of MDMV. MDMV-Sp and SCMV-Sp differed from each other by 31% in their nucleotide sequences. Phylogenetic analyses showed that SCMV isolates group by host rather than by geographical location. Two significant recombination signals were identified in the NIa and NIb regions of the SCMV-Sp genome.
对西班牙分离的玉米矮花叶病毒（MDMV-Sp）和甘蔗花叶病毒（SCMV-Sp）的基因组进行了全序列测定。SCMV-Sp与其他SCMV分离株的核苷酸序列同一性在79%至90%之间。MDMV-Sp与唯一一株已完成全序列测定的MDMV分离株的核苷酸同一性为85%。MDMV-Sp和SCMV-Sp的核苷酸序列彼此相差31%。系统发育分析表明，SCMV分离株按宿主而非地理位置聚类。在SCMV-Sp基因组的NIa和NIb区域鉴定出两个显著的重组信号。
