Field mustard plants present in cauliflower fields were observed exhibiting branch proliferation, small and deformed leaves and flowers. The virtual RFLP and online tool iPhyclassifier identified phytoplasmas of the 16SrIII-B, 16SrIII-J, 16SrIII-U and 16SrVII-B subgroups. Representatives of these subgroups were previously identified in cauliflower. This study evidenced field mustard as a host that can serve as inoculum source for commercial crops.
