Abstract: A previously uncharacterized virus was reported in southeast Brazil causing a yellowing leaf disease in sugarcane. The virus, termed sugarcane yellow leaf virus (ScYLV), shares features typical of the luteoviruses. To start the molecular characterization of ScYLV, the nucleotide sequence of the coat protein (CP), 17 kDa protein and C-terminus of the RNA-dependent RNA polymerase coding regions was determined from an RT-PCR amplification product. Comparisons showed that the deduced amino acid sequences share a considerable degree of identity and similarity with corresponding sequences of known luteoviruses, thus clearly establishing ScYLV as a member of the family Luteoviridae. The authenticity of the CP open reading frame was confirmed by its expression in Escherichia coli. The recombinant CP positively reacted in immunoblot assays with polyclonal antibodies raised against native ScYLV. Furthermore, phylogenetic analyses also suggest that the 5' and 3' coding blocks of the ScYLV genome possess different taxonomic affinities within the Luteoviridae family, as does also the genome of soybean dwarf virus.
