Abstract

Since the 1970s, several dsRNA viruses, including Radish yellow edge virus, Raphanus sativus virus 1, Raphanus sativus virus 2, and Raphanus sativus virus 3, have been identified and reported as infecting radish. In the present study, in conjunction with a survey of seed-borne viruses in cultivated Brassica and Raphanus using the dsRNA diagnostic method, we discovered 3 novel cryptoviruses that infect Brassica and Raphanus: Raphanus sativus partitivirus 1, which infects radish (Raphanus sativus); Sinapis alba cryptic virus 1, which infects Sinapis alba; and Brassica rapa cryptic virus 1 (BrCV1), which infects Brassica rapa. The genomic organization of these cryptoviruses was analyzed and characterized. BrCV1 might represent the first plant partitivirus found in Gammapartitivirus. Additionally, the evolutionary relationships among all of the partitiviruses reported in Raphanus and Brassica were analyzed.
