Interpretive Summary: Technical Abstract: A new virus disease has emerged in the Midsouth and Southeastern United States and was named blackberry yellow vein disease (BYVD). Originally, it was thought the disease was caused by Tobacco ringspot virus (TRSV) as the virus was found in many diseased plants and symptoms were very similar to those attributed to TRSV in the past. It was later realized that TRSV is asymptomatic in many modern blackberry cultivars, and there was a plethora of diseased plants that were not infected with the virus. Several new viruses have been identified in BYVD-affected plants. The majority of the new viruses are asymptomatic in single infections and symptoms appear when two or more of the viruses accumulate in plants. Symptoms are not associated with any given virus combination and different combinations can cause identical symptoms making BYVD one of the most complex diseases of small fruit crops. The identity of the viruses found in BYVD changes depending on the geographic location with Blackberry yellow vein associated virus (BYVaV) being the most common virus in diseased plants. For example in Arkansas, BYVaV and Blackberry virus Y (BVY) are the viruses more frequently found in BYVD plants whereas in North and South Carolina the combination of BYVaV with TRSV is more prominent. The viruses identified for the first time in Rubus spp. in BYVD plants and described in this section are: BYVaV, BVY, Beet pseudo-yellows virus, Blackberry virus X, Blackberry virus E, Blackberry virus S, Rubus virus R and Impatiens necrotic spot virus. |
