The pathogenicity mechanisms of phytoplasmas has been documented for several ribosomal groups, but there is a lack of information for the 16SrIII group. Phytoplasmas in this ribosomal group were detected in most of the countries of South America, in different crops, from herbaceous to woody species. This works aimed to verify if the in planta transient expression of putative phytoplasma effector proteins allow to observe symptoms related to those associated with phytoplasma diseases. Plants infected with Tobacco mosaic virus vector carrying 16SrIII-J phytoplasma SAP54 and SAP05 ortologous genes, showed flowering abnormalities in comparison to those not infected or infected with the viral vector alone indicating a putative role of these proteins in 16SrIII-J phytoplasma symptom induction.
