Geographic Distribution
Until 2007 the only place this virus was known was in the USA, in particular in the state of Florida. 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). The nucleotide sequences of the two were 94% identical and the deduced amino acid sequences were 98% identical. At the time it was suggested that SCSV and BiMoV were one and the same.
Another publication in 2008 directly compared the sequences of a second isolate of BiMoV from Florida to the sequence of SCSV from Taiwan. The authors of the article concluded that "the sunflower chlorotic spot virus described from Taiwan is in fact an isolate of BiMoV". In addition, an isolate of what was believed to be SCSV (based on sequences available in 2004) was found in the State of São Paulo in Brazil.
Taken together these reports likely mean that the geographical distribution of BiMoV now includes Taiwan and Brazil in addition to the USA. (It should be noted here that when two named viruses are found to be identical, precedence is given to the virus name reported first in the literature.)

Famous quotes containing the word distribution:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
