Key Findings
- Researchers at University Roma Tre studied how manipulating thermospermine (T-Spm) metabolism affects stress tolerance in tomato plants
- They used CRISPR/Cas9 to create tomato mutants with higher T-Spm levels, leading to changes in growth and xylem structure
- These mutants showed improved drought tolerance by reducing water loss and vulnerability to embolism, enhancing plant resilience
