Gene Details:

• Gene ID: Potri.008G166100
• Gene Symbol: PtoERF15
• Gene Name: ETHYLENE RESPONSE FACTOR 15
• Genome:
• Species: Populus tomentosa

Functional Descriptions:

• The AP2/ERF transcription factor PtoERF15 confers drought tolerance via JA-mediated signaling in Populus.
• 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 is preferentially expressed in differentiating xylem of poplar stems. Overexpression of PtoERF15 contributed to stem water potential maintaining, thus promoting drought tolerance.
• 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.
