Key Findings
- Researchers at Zhejiang University found that strigolactones help tomato plants tolerate cold by regulating autophagy and protein degradation
- Cold stress causes an accumulation of damaged proteins in tomato plants, which strigolactones help reduce by enhancing autophagy
- The study identified that the transcription factor HY5, activated by strigolactones, is crucial for initiating autophagy and improving cold tolerance in tomatoes
