| Outline of Final Research Achievements |
Phytoplasmas are intracellular bacterial pathogens of plants and insects and cause devastating yield losses in diverse low- and high-value crops worldwide. To investigate the molecular mechanisms of the regulation of the host cells, we focused on phytoplasma-secreted proteins. As a result of screening, we found a phytoplasma-secreted protein, PHYL1, which induces morphological changes in flowers that are similar to those seen in phytoplasma-infected plants. By yeast two-hybrid and in planta transient coexpression assays, we found that PHYL1 interacts with and degrades floral homeotic MADS-domain proteins.
