Gene Details:

  • Gene ID:
  • Gene Symbol: SlERF52
  • Gene Name: ETHYLENE-RESPONSIVE FACTOR 52
  • Genome: Tomato Genome version SL4.0
  • Species: Solanum lycopersicum

Functional Descriptions:

  • SlERF52 regulates SlTIP1;1 expression to accelerate tomato pedicel abscission.
  • SlERF52 bound directly to the SlTIP1;1 promoter to regulate its expression, demonstrating a positive loop in which cytoplasmic H2O2 activates ETH production, which activates SlERF52.
  • These results suggest that ETH induces SlERF52 to activate SlTIP1;1 expression, and that SlTIP1;1 functions downstream of the ETH signal to accelerate abscission.
  • SlERF52 bound directly to the SlTIP1|1 promoter to regulate its expression, demonstrating a positive loop in which cytoplasmic H2O2 activates ETH production, which activates SlERF52.
  • These results suggest that ETH induces SlERF52 to activate SlTIP1|1 expression, and that SlTIP1|1 functions downstream of the ETH signal to accelerate abscission.
  • SlERF52 is specifically expressed in pedicel abscission zones (AZs) and SlERF52 expression is suppressed in plants with impaired function of MACROCALYX and JOINTLESS, which regulate pedicel AZ development.
  • SlERF52 suppression also affected gene expression before the abscission stimulus, inhibiting the expression of pedicel AZ-specific transcription factor genes, such as the tomato WUSCHEL homologue, GOBLET, and Lateral suppressor, which may regulate meristematic activities in pedicel AZs.
  • These results suggest that SlERF52 plays a pivotal role in transcriptional regulation in pedicel AZs at both pre-abscission and abscission stages.
