Melon yellow spot orthotospovirus (MYSV, genus Orthotospovirus, family Tospoviridae) is naturally transmitted by Thrips palmi (Kato et al. 1999). It was initially identified from a melon (Cucumis melo) plant in Shizuoka Prefecture, Japan (Kato et al. 2000). To date, MYSV has been identified to infect several cucurbits such as watermelon, melon, balsam pear, cucumber, pumpkin, wax gourd, and luffa. The virus has also been detected in pepper (Supakitthanakorn et al. 2018). In May 2018, a viral-like disease was observed on broad beans (Vicia faba L.) in a ∼0.4-ha field in Shangyu County, Zhejiang Province, China. Diseased plants were dwarf, and numerous necrotic spots appeared on the upper leaves. To identify viral agents potentially associated with this disease, a sRNA library from a symptomatic sample was generated and sequenced. Total RNA was extracted using RNAiso Plus (TaKaRa, Tokyo, Japan). Libraries were constructed using a TruSeq Small RNA Library preparation kit (Illumina, San Diego, CA). Approximately 21 million raw reads were obtained from the Illumina MiSeq platform. After removing the adapters and low-quality reads, the clean reads within the range of 18 to 26 nt were analyzed using VirusDetect, a program that can efficiently identify plant viruses and viroids from deep siRNA sequences (Zheng et al. 2017). Contig assembly and BLASTn analysis against the reference virus genomes in the NCBI database led to the identification of 117 contigs with high (94.4 to 100%) nucleotide identity to the genome of MYSV. These contigs mapped to the MYSV genomic RNAs (L, M, and S) with 62.2 to 86.5% coverage. Besides MYSV, no other viruses or viroids were found in the sample. Based on the assembled contigs and the reference MYSV genome, we designed eight primer pairs to obtain the sequence of MYSV Zhejiang (MYSV-ZJ) isolate L, M, and S segments. Briefly, total RNA from MYSV-infected broad bean was extracted using RNAiso Plus. Reverse transcription was conducted using avian myeloblastosis virus reverse transcription (TaKaRa) with random primers N6 (TaKaRa). Segments of MYSV were amplified using high-fidelity DNA polymerase KOD-Plus-Neo (Toyobo, Osaka, Japan). PCR products were cloned into the pLB vector (Tiangen, Beijing, China) and Sanger sequenced. The obtained sequences were assembled into three near-complete sequences of MYSV-ZJ genomic L (8,869 nt; MN550994), M (4,870 nt; MN550995), and S (3,208 nt; MN550996). Pairwise sequence comparison revealed that the MYSV-ZJ shared the highest nucleotide sequence identities of 97.3 to 98.3% with the genome segments of Hainan isolate (MH734110 to MH734112). We performed reverse transcription PCR detection on all collected samples using primers MYSV-N-F and MYSV-N-R designed on the sequence of MYSV-ZJ to amplify the MYSV N gene. Seven of 20 randomly collected samples (symptomatic = 9, asymptomatic = 11) were positive for MYSV. None of the asymptomatic samples tested positive for the virus. In addition, MYSV was also not detected from two symptomatic samples, and it is not known the cause of the symptom. To the best of our knowledge, this is the first report of MYSV infecting broad bean. With the widespread presence of T. palmi in broad bean fields, MYSV may be an underlying threat to the cultivation of broad beans in China.
