| BCRVS is a short (and accepted) version of the name Blackberry chlorotic ringspot virus. As you might expect from the name, this virus was first described from Blackberries. The description was done by A. Jones et al in Scotland.
Somehow this virus is also present in roses in the USA. It was first found (through molecular studies) on Rosa multiflora in Arkansas. The R. multiflora plants were not planted by man but were found in places where they were likely to have grown from seeds dropped by birds. These plants were not expected to have any viruses. A reference that is available in .pdf form is in Plant Pathology 2006, vol. 55, page 568. Senior author is I.E. Tzanetakis. In brambles, the disease often has no visible expression in symptoms; but it does sometimes manifest itself as chlorotic ringspots which are hazy ringspots with less dense cholorphyll than the surrounding leaf material. |

| I have a copy of the August 2011 University of Arkansas Masters Thesis of Bindu Poudel. The BCRV virus is reported to have a 58% multiflora rose seed transmission rate (the following is a quote from the thesis: "and should act as an alarm bell to breeders because of the high percentage of seed transmission."). Infected roses were found in both Arkansas and Missouri, but the virus was found: (Quote from the thesis: "BCRV has been found to naturally infect blackberry, raspberry and rose facilitating the virus survival and complicating its epidemiology. The geographical distribution of BCRV includes Arkansas, Oregon, California, Missouri, North Carolina, South Carolina, Georgia and Tennessee. Apart from United States the virus is also found in the United Kingdom, where it was first isolated."). The virus was first reported in roses in 2006. From thesis: "Out of the 26 species of plants tested as potential alternative host the virus was detected in one apple tree sample. This sample tested positive in two consecutive PCRs and the products were sequenced to confirm the presence of the virus." |

| I had to laugh, karl. That was exactly my first thought also--and I hadn't even read your response yet. And to think that I once upon a time just raised roses to enjoy their beauty without any worry at all. Ignorance is bliss? Kate |

| I still raise roses to enjoy their beauty. I try to ignore the diseases, all the while trying to learn all I can about them. |

| Great one Karl! |
