The cucurbit vegetable chieh-qua (Benincasa hispida var.chieh-qua How) is an important crop in South China and southeast Asian countries.Viral diseases cause substantial loss of chieh-qua yield.To identify the viruses that affect chieh-qua in China, ribosomal RNA-depleted total RNA sequencing was performed using chieh-qua leaf samples with typical viral symptoms.

The virome of chieh-qua iphone 13 price dallas comprises four known viruses (melon yellow spot virus (MYSV), cucurbit chlorotic yellows virus (CCYV), papaya ringspot virus (PRSV) and watermelon silver mottle virus (WSMoV) and two novel viruses: cucurbit chlorotic virus (CuCV) in the genus Crinivirus and chieh-qua endornavirus (CqEV) in the genus Alphaendornavirus.The complete genomes of the two novel viruses in chieh-qua and three other isolates of CuCV in pumpkin, watermelon and cucumber were determined and the recombination signals of pumpkin and watermelon isolates of CuCV were detected.A reverse transcriptase PCR indicated that the dominant viruses of chieh-qua in Hainan are flex 4 heartworm test MYSV (66.67%) and CCYV (55.

56%), followed by CuCV (27.41%), WSMoV (7.41%), cucumber mosaic virus (8.15%), zucchini yellow mosaic virus (6.

67%), PRSV (6.67%) and CqEV (35.56%).Our findings support diagnostic and prevalence studies of viruses infecting chieh-qua in China, enabling sustainable control strategies for cucurbit viruses worldwide.
