Gene Details:

• Gene ID: Potri.003G092200
• Gene Symbol: PtoMYC2b
• Gene Name:
• Genome:
• Species: Populus tomentosa

Functional Descriptions:

• Here, we identified and characterized an osmotic stress-induced ETHYLENE RESPONSE FACTOR 15 (PtoERF15) and its target, PtoMYC2b, which was involved in mediating vessel size, density, and cell wall thickness in response to drought in Populus tomentosa.
• PtoERF15 directly regulated PtoMYC2b, encoding a switch of JA signaling pathway.
• Collectively, our study provides molecular evidence for the involvement of the PtoERF15-PtoMYC2b transcription cascade in maintaining stem water potential through the regulation of xylem vessel development, ultimately improving drought tolerance in poplar.
• PtoMYC2b acts downstream of PtoERF15 to improve drought tolerance.
