Key Findings
- Researchers at Dalian University of Technology discovered that a small peptide, miPEP396a, is produced by the miRNA miR396a in tomatoes
- miPEP396a is located in the nucleus and regulates the expression of its own pri-miR396a, miR396a, and their target genes
- Applying miPEP396a in vitro significantly inhibited the elongation of tomato primary roots, showing its role in root development
