Gene Details:

• Gene ID: Pbr000876.1
• Gene Symbol: PpMYB140
• Gene Name:
• Genome:
• Species: Pyrus pyrifolia

Functional Descriptions:

• Ethylene-activated PpERF105 induces the expression of the repressor-type R2R3-MYB gene PpMYB140 to inhibit anthocyanin biosynthesis in red pear fruit.
• PpERF105 functioned as a transcriptional activator, but it inhibited anthocyanin biosynthesis in pear. A transcriptome analysis revealed that PpERF105 activated the expression of PpMYB140, which encodes an R2R3-MYB transcriptional repressor.
• Collectively, our study data indicate that ethylene-induced PpERF105 inhibits anthocyanin biosynthesis by upregulating PpMYB140 expression.
• PpMYB140 directly inhibited the expression of anthocyanin-related structural genes.
