Characterization of a new whitefly-transmitted (Bemisia tabaci Meam 1) cytorhabdovirus infecting common bean.

Common bean (Phaseolus vulgaris) is an important crop in Latin America and Africa. The bean yield may be affected by the incidence of different viruses. As part of a virus survey in beans, we have used high-throughput sequencing approach to identify viruses with RNA genome in bean plants collected in Goias (GO) state. Bioinformatic analysis of the de novoassembled contigs identified a putative cytorhabdovirus (family Rhabdoviridae) with low similarities with Northern cereal mosaic virus (NCMV). This new cytorhabdovirus was denominated Bean associated cytorhabdovirus (BaC). Cytorhabdoviruses have enveloped particles, negative ssRNA of 11-14 kb genome and are usually transmitted by aphids or leafhoppers.
