Unveiling the Effector-Triggered Immunity Landscape in Tomatoes Against Pseudomonas syringae

Summary: A comprehensive study has mapped out the effector-triggered immunity (ETI) landscape of tomatoes against the bacterial pathogen Pseudomonas syringae. Researchers screened a diverse collection of tomato varieties, including cultivated and wild species, to identify ETI-eliciting effectors and assess their potential for crop protection.Key findings include:

• Six effector families were identified as ETI-eliciting in tomatoes, with five previously uncharacterized.
• The tomato ETI landscape differs significantly from that of Arabidopsis thaliana, with only 19% conservation.
• ETI responses were found to be broadly distributed across wild and cultivated tomato varieties.
• ETI-eliciting effectors demonstrated potential as immunoprotective agents against P. syringae infection.

This research provides valuable insights into tomato immune responses and opens new avenues for developing disease-resistant crops and biocontrol strategies in agriculture.
