Key Findings
- Researchers at Korea University discovered how the hormone systemin triggers defense responses in tomato plants
- Systemin binds to the receptor SYR1, which then partners with SERK proteins to activate defense mechanisms
- This activation involves mutual phosphorylation between SYR1 and SERKs, leading to the phosphorylation of TPK1b, a key protein in defense signaling
