Gene Details:

• Gene ID: Gh_D02G1817
• Gene Symbol: GhERF9
• Gene Name: ethylene response factor 9
• Genome: TM1_NBI
• Species: Gossypium hirsutum

Functional Descriptions:

• Here, we have demonstrated that one of the ERF TFs in cotton, GhERF9, exerts a regulatory role in enhancing the expression of GhHAK5a by binding to its promoter region.
• The yeast one-hybrid screening was performed to identify the transcription factors responsible for regulating GhHAK5a, and ethylene response factor 9 (GhERF9) was identified as a potential candidate.
• Silencing of GhERF9 decreased the expression of GhHAK5a and exacerbated K+ deficiency symptoms in leaves, also decreased K+ uptake rate and K+ content in roots.
• Additionally, it was observed that the application of ethephon (an ethylene-releasing reagent) resulted in a significant upregulation of GhERF9 and GhHAK5a, accompanied by an increased rate of K+ uptake. Expectedly, GhEIN3b and GhEIL3c, the two key components involved in ethylene signaling, bind directly to the GhERF9 promoter.
