Abstract:
A new cytorhabdovirus was identified in zucchini (Cucurbita pepo) in Greece with the aid of high-throughput sequencing technology. The negative-sense, single-stranded genomic RNA of the new virus was determined and includes seven open reading frames in the order 3'-N-P-P3-P4-M-G-L-5' in the antigenomic orientation. Typical rhabdovirus-like particles were observed in infected leaf material. Comparative sequence analysis and phylogenetic reconstructions suggested that the described virus is a new member of the genus Cytorhabdovirus, and it was tentatively named cucurbit cytorhabdovirus 1 (CuCV1). To our knowledge CuCV1 is the first cytorhabdovirus infecting cucurbits in nature. Our surveys indicated that it occurs in a percentage of 36.7 % in zucchini crops in Greece.
