Geographic Distribution and Host Range
Pepper mottle was first recognized as an new strain of PVY infecting peppers in Arizona in 1969. In the early 1970s an "atypical" PVY isolate was also found in a survey of pepper fields in central Florida. Up until then, the two most important potyviruses infecting peppers in the US were Tobacco etch virus (TEV) and Potato virus Y (PVY). By 1975 it was clear that a third potyvirus, PepMoV (PeMV), was contributing to crop losses in pepper growing areas of the United States. It has also been found in California, New Mexico, Texas, and in Central America (El Slavador) (3). In 2003, it was reported in C. annuum in Japan.
This virus infects many species of Solanaceae, including several species of Capsicum (i.e. C. annuum, C. frutescens), Datura spp., Lycopersicon esculentum, Physalis floriana, tobacco (Nicotiana spp.) and nightshade (Solanum sp.) (2,4). It was its reaction on C. frutescens (Tabasco pepper) that alerted researchers to the presence of a new virus in peppers.

Famous quotes containing the words distribution, host and/or range:
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Thrust, my daughter or son, to escape, there is none, none, none,
Nor when all ponderous heaven’s host of waters breaks.”
—Dylan Thomas (1914–1953)
“In the range of things toddlers have to learn and endlessly review—why you can’t put bottles with certain labels in your mouth, why you have to sit on the potty, why you can’t take whatever you want in the store, why you don’t hit your friends—by the time we got to why you can’t drop your peas, well, I was dropping a few myself.”
—Mary Kay Blakely (20th century)
