 In 2007, the virus was identified in a new host in Florida and it was partially sequenced for the first time.When the sequence of 247 base pairs was compared to other potyvirus sequences in GenBank it matched a virus found in Taiwan tentatively called "Sunflower chlorotic spot virus" (SCSV) whose sequence had been deposited in the GenBank in 2001 (GenBank Accession No.AF538686).
