• Information
  • Symbol: OsERF106MZ
  • MSU: None
  • RAPdb: None
• Publication
  • Overexpression of a Novel ERF-X-Type Transcription Factor, OsERF106MZ, Reduces Shoot Growth and Tolerance to Salinity Stress in Rice., 2021, Rice (N Y).
  • Overexpression of OsERF106MZ promotes parental root growth in rice seedlings by relieving the ABA-mediated inhibition of root growth under salinity stress conditions., 2023, BMC Plant Biol.
• Genbank accession number
  • MZ561461
• Key message
  • The novel transcription factor OsERF106MZ negatively regulates shoot growth and salinity tolerance in rice through the disruption of ion homeostasis and modulation of stress-responsive gene expression
  • Overexpression of OsERF106MZ led to retardation of growth, relatively high levels of both malondialdehyde (MDA) and reactive oxygen species (ROS), reduced catalase (CAT) activity, and overaccumulation of both sodium (Na(+)) and potassium (K(+)) ions in transgenic rice shoots
  • OsERF106MZ is expressed in germinating seeds, primary roots, and developing flowers
  • Overexpression of OsERF106MZ promotes parental root growth in rice seedlings by relieving the ABA-mediated inhibition of root growth under salinity stress conditions.
  • RESULTS: Histochemical staining to examine β-glucuronidase (GUS) activity in transgenic rice seedlings harboring OsERF106MZp::GUS indicated that OsERF106MZ is mainly expressed in the root exodermis, sclerenchyma layer, and vascular system
  • OsERF106MZ overexpression in rice seedlings leads to an increase in primary root (PR) length
  • However, the roles of OsERF106MZ in root growth remain poorly understood
  • CONCLUSIONS: OsERF106MZ may play a role in maintaining root growth for resource uptake when rice seeds germinate under salinity stress by alleviating ABA-mediated root growth inhibition
  • OsERF106MZ is a salinity-induced gene that is expressed in germinating seeds and rice seedling roots
• Connection
  • OsAO3, OsERF106MZ, Overexpression of OsERF106MZ promotes parental root growth in rice seedlings by relieving the ABA-mediated inhibition of root growth under salinity stress conditions., Furthermore, chromatin immunoprecipitation (ChIP)-qPCR and luciferase (LUC) reporter assays showed that OsERF106MZ can bind directly to the sequence containing the GCC box in the promoter region of the OsAO3 gene and repress the expression of OsAO3
