Key Findings
- Researchers at Nanjing Agricultural University discovered that the PyMYB107 gene represses anthocyanin production in red-skinned pears
- Overexpression of PyMYB107 reduces anthocyanin levels, while silencing it increases these pigments
- PyMYB107 competes with other transcription factors, disrupting the activation of genes needed for anthocyanin biosynthesis
