The most prevalent virus inducing MDM in China is Sugarcane mosaic virus (SCMV) (Jiang and Zhou 2002; Li et al. 2013). SCMV isolates were clustered into four groups according to the phylogenetic analysis of their complete genomic sequences, among which group IV represented by highly virulent BD8 was a novel strain (Gao et al. 2011). In 2015, the incidence of MDM was up to 30% in some fields in Shandong and Hubei provinces. From July to September, 22 corn leaf samples showing MDM symptoms were collected from corn cultivar Xianyu 333 in Tai’an of Shandong Province and Shijiazhuang of Hebei Province, cultivar Zhengdan 958 in Jingzhou of Hubei Province, and cultivar Denghai 11 in Chuxiong of Yunnan Province. All the samples were positive in PTA-ELISA detection with SCMV specific antibody (Li et al. 2003). Total RNA was extracted from six ELISA-positive samples. The CP fragments were amplified by RT-PCR with primer pair SCMV-F (5′-AGTGATGCAGCTGAAGC-3′) and SCMV-R (5′-TGGCTCGACGCTAGTAC-3′). Sequencing results showed that isolates CN:DWK2:15 from Tai’an, Shandong Province and CN:HB:15 from Jingzhou, Hubei Province were genetically identical to BD8 isolate. To check the relationship of these two new isolates with BD8 isolate, their complete genomes were amplified with previously reported primers (Gao et al. 2011). The complete genome sequences of isolates CN:DWK2:15 (GenBank Accession No. KU171815) and CN:HB:15 (KU171817) were 95.1% identical, and were 99.5% and 95.1% identical with that of SCMV BD8 (JN021933), respectively. In contrast, these isolates had 80.4% or lower sequence identity with SCMV isolates in other groups. Based on phylogenetic analysis of complete genome, both CN:DWK2:15 and CN:HB:15 were clustered in group IV together with BD8 isolate. Isolate CN:DWK2:15 was inoculated onto 28 commercially available corn cultivars and induced severe MDM symptoms with incidence of 12.5 to 93.3% in 19 cultivars, most of which were resistant to SCMV isolates of other groups. The plants of three cultivars were asymptomatic but positive in ELISA and RT-PCR detection. BD8-like isolates were detected in Thailand, Vietnam (Gao et al. 2011), and East Africa (Mahuku et al. 2015). However, this is the first report on the occurrence of SCMV group IV isolates in corn production fields in China. Further monitoring is warranted to determine the full distribution of the isolate and its ability to cause disease on widely used maize hybrids.References:Gao, B., et al 2011.
