Characterization of sida golden mottle virus isolated from S ida santaremensis Monteiro in Florida

AbstractThe genome of sida golden mottle virus (SiGMoV) (GU997691 and GU997692) isolated fromSida santaremensis Monteiro in Manatee County, Florida, was sequenced and characterized. SiGMoV was determined to be a bipartite virus belonging to the genusBegomovirus with a genome organization typical of the New World viruses in the genus. SiGMoV DNA-A had the highest identity scores (89%) and showed the closest evolutionary relationships to sida golden mosaic Buckup virus (SiGMBuV) (JX162591 and HQ008338). However, SiGMoV DNA-B had the highest identity scores (93%) and showed the closest evolutionary relationship to corchorus yellow spot virus (DQ875869), SiGMBuV (JX162592) and sida golden mosaic Florida virus (SiGMFlV) (HE806443). There was extensive recombination in the SiGMoV DNA-A and much less in DNA-B. Full-length clones of SiGMoV were infectious and were able to infect and cause symptoms in several plant species.
