Characterization of the first Rubus yellow net virus genome from blackberry

Rubus yellow net virus (RYNV) is a badnavirus that infects Rubus spp. Mixed infections with black raspberry necrosis virus and raspberry leaf mottle virus cause raspberry mosaic, a disease that leads to significant losses and even plant death. RYNV has been reported in several European countries and the Americas yet there is substantial lack of knowledge, especially when it comes to virus diversity and the evolutionary forces that affect virus fitness outside its primary host, raspberry. Herein, we report the first RYNV episomal genome isolated from blackberry and this is the first report of the virus in Bosnia and Herzegovina. The isolate has five open reading frames (ORFs) and, when compared with other fully sequenced counterparts, showed 82-97% nucleotide pairwise identity. This communication adds to our limited knowledge on RYNV and addresses some of the gaps in RYNV genetics when it comes to the coding capacity of episomal isolates and the probability of the first fully sequenced isolate of the virus being integrated in the raspberry genome.
