Gene Details:

  • Gene ID: Ach02g251101.2
  • Gene Symbol: AcKUP2
  • Gene Name: K+ transporter KT/HAK/KUP 2
  • Genome:
  • Species: Actinidia chinensis

Functional Descriptions:

  • Ethylene-induced potassium transporter AcKUP2 gene is involved in kiwifruit postharvest ripening.
  • Transcription analysis revealed that AcKUP2 expression increased rapidly and was maintained at a high level during postharvest maturation, consistent with the trend of K content| AcKUP2 expression was induced by ethylene, suggesting that AcKUP2 might play a role in ripening.
  • Found in the AcKUP2 promoter sequence, and ethylene significantly enhanced the AcKUP2 promoter activity. Furthermore, we verified that AcERF15, an ethylene response factor, directly binds to the AcKUP2 promoter to promote its expression.
  • AcKUP2 may be an important potassium transporter gene which involved in ethylene-regulated kiwifruit postharvest ripening.
  • AcKUP2, a member of group II, was located on the plasma membrane, thereby verifying its K+ transporter activity.
