dc.descriptionPlants of Senna occidentalis (sin. Cassia occidentalis) with mosaic symptoms were collected near a soybean (Glycine max) field where some plants exhibited symptoms of mosaic and blistering. A preliminary examination of leaf tissue from diseased S. occidentalis by electron microscopy revealed the presence of pinwheel inclusions as well as long flexuous particles, indicating the presence of a potyvirus. Host range, serology, and amino acid sequence from this potyvirus were similar to those from other Brazilian isolates of Soybean mosaic virus (SMV). The 3´- terminal region of the genomic RNA was cloned and a cDNA sequence of 1.9 kb upstream of the poly (A) tract was determined. The sequence contains a single open reading frame and a 3´- non-translated region (NTR) of 259 bp. The nucleotide sequence of the CP gene of SMV-Soc was 98% identical to that of Brazilian isolates SMV-B, SMV-L, and SMV-FT10. The percentage of nucleotide identity of their 3'-NTR's was 91, 98, and 99% in relation to SMV-L, SMV-B, and SMV-FT10, respectively. In contrast to other Brazilian SMV isolates studied, SMV-Soc was able to infect sunflower (Helianthus annuus). Based on these results, the S. occidentalis isolate was identified as a new strain of SMV belonging to the SMV strain, group G5 and was named SMV-Soc. This is the first report of naturaly occurring SMV infecting plants of S. occidentalis in Brazil, adding this weed as a new source of SMV in the field.
