anglais. 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 Goiás (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.
