The Good, the Bad, and the Ugly: What the Future Could Hold for Bs2 Tomatoes
Bacterial spot resistance in tomato conferred by the pepper  Bs2 gene. On the left are symptomless Bs2 transgenic plants of the  hybrid, Fla. 8314; on the right are severely infected non-transgenic  plants of the cultivar VF36. The picture was taken from a trial  conducted in Florida in spring 2012, for which all plants in the trial  were inoculated with the bacterial spot pathogen.

Bs2 tomatoes are transgenic tomatoes that have been engineered to contain the Bs2 gene from pepper. As such, they are considered a genetically modified (GM) food, or a genetically modified organism (GMO). Numerous trials conducted by University of Florida researchers have shown the benefits of these cultivars for bacterial spot disease management, and growers and industry members recognize the potential for Bs2 tomatoes to make Florida tomato production more sustainable. This 4-page fact sheet discusses the benefits that might be realized by the adoption of Bs2 tomato varieties, and the challenges standing in the way of their commercial production. Written by S. F.
