|a Rice black-streaked dwarf virus is transmitted by small brown planthoppers, which causes maize rough dwarf disease and rice black-streaked dwarf disease. This virus leads to slow growth or death of the host plants. During the coevolutionary arms race between viruses and plants, virus-derived small interfering RNAs (vsiRNAs) challenge the plant's defense response and inhibit host immunity through the RNA silencing system. However, it is currently unknown if rice black-streaked dwarf virus can produce the same siRNAs to mediate the RNA silencing in different infected species. In this study, four small RNA libraries and four degradome libraries were constructed by extracting total RNAs from the leaves of the maize (Zea mays) inbred line B73 and japonica rice (Oryza sativa) variety Nipponbare exposed to feeding by viruliferous and nonviruliferous small brown planthoppers. We analyzed the characteristics of small RNAs and explored virus-derived siRNAs in small RNA libraries through high-throughput sequencing. On analyzing the characteristics of small RNA, we noted that the size distributions of small RNAs were mainly 24 nt (19.74 to 62.00%), whereas those of vsiRNAs were mostly 21 nt (41.06 to 41.87%) and 22 nt (39.72 to 42.26%). The 5'-terminal nucleotides of vsiRNAs tended to be adenine or uracil. Exploring the distribution of vsiRNA hot spots on the viral genome segments revealed that the frequency of hotspots in B73 was higher than those in Nipponbare. Meanwhile, hotspots in the S9 and S10 virus genome segments were distributed similarly in both hosts. In addition, the target genes of small RNA were explored by degradome sequencing. Analyses of the regulatory pathway of these target genes unveiled that viral infection affected the ribosome-related target genes in maize and the target genes in the metabolism and biosynthesis pathways in rice. Here, 562 and 703 vsiRNAs were separately obtained in maize and rice and 73 vsiRNAs named as coexisting vsiRNAs (co-vsiRNAs) were detected in both hosts. Stem-loop PCR and real-time quantitative PCR confirmed that co-vsiRNA 3.1 and co-vsiRNA 3.5, derived from genome segment S3, simultaneously play a role in maize and rice and inhibited host gene expression. The study revealed that rice black-streaked dwarf virus can produce the same siRNAs in different species and provides a new direction for developing new antiviral strategies
