Research Abstract |
Phytoplasmas are bacterial plant pathogens and bring about dramatic changes in plant development, including witches' broom, dwarfism, proliferation, and phyllody. In this study, we focused on the secreted proteins encoded in the phytoplasma genome, and screened the virulence factor of phytoplasma. As a result, we found that a single virulence factor, named TENGU, induced witches' broom and dwarfism. The functional analysis of TENGU revealed that TENGU inhibits auxin-related pathways, thereby affecting plant development.
