Title: Two new begomoviruses found infecting Solanaceous crops in Cuba

Summary:

Significance: In 2007, two new begomoviruses viruses were found to be affecting Solanaceous crops in eastern Cuba. Both are newly determined viruses with proposed names, and little information is known regarding the full host range or distribution of either. In general, begomoviruses are transmitted by the whitefly, Bemisia tabaci, which is present worldwide and can be transported through movement of nursery stock, cut flowers, or wind. At this point, it is unclear what impacts these viruses may have on their host crops.

Tomato yellow leaf distortion virus (ToYLDV) was determined to be infecting tomato (Solanum lycopersicum). Symptoms of ToYLDV include yellow mottle and leaf distortion.

Tobacco yellow crinkle virus (TbYCV) was determined to be infecting tobacco (Nicotiana tabacum) and sweet pepper (Capsicum annuum). Symptoms of TbYCV on tobacco include foliar yellowing and crinkling. Symptoms of TbYCV on sweet pepper plants were foliar yellow mottle.
