The following historical description of what was then known as rose leaf curl (suspected virus) was published in 1977.
"The first disease discovered, now known in California as rose leaf curl (RLC), is widely distributed in the United States. It was found in several community rose gardens in midwestern and southern states in 1976."
"Rose leaf curl has been found only in public rose gardens, usually in or near plants of “antique” roses. Recent data indicate a slow natural spread, although the vector is unknown. Hybrid tea roses exhibit RLC symptoms, but rootstock varieties do not. Symptoms on hybrid tea roses are downward curling of leaves on established plants and dieback of canes (fig. 4). Leaves easily drop off new shoots, and the shoots are characteristically pointed with a broad base."

In the 1970s scientists did not have the ability to isolate and molecular characterize viruses so one cannot be certain that the "new" Rose leaf curl virus is the same as the one described above.

The following is a 2014 published, reviewed, scientific paper that appears to characterize the above virus. The title is:
"First report of a begomovirus and associated betasatellite in Rosa indica and in India"
Of interest is the picture of a diseased rose and the finding that this virus is whitefly transmitted to the following plants: roses, cotton, radish, tomato, papaya, chili, and bhendi (see Table 1).
"Our results showed that the virus was transmitted by whiteflies in a persistent manner and caused systemic leaf curling and stunting on host plants (Table 1)."
