Gene Details:

Functional Descriptions:

  • Transcription factor CmHSFA4-CmMYBS3 complex enhances salt tolerance in chrysanthemum by repressing CmMYB121 expression.
  • Identified a candidate MYB transcription factor, CmMYB121, which responded to salt stress.
  • CmHSFA4 directly bound to the promoter of CmMYB121 at the heat-shock element. Protein–protein interaction assays identified an interaction between CmHSFA4 and CmMYBS3, a transcriptional repressor, and recruited the corepressor TOPLESS (CmTPL) to inhibit CmMYB121 transcription by impairing the H3 and H4 histone acetylation levels of CmMYB121.
  • CmHSFA4–CmMYBS3–CmTPL complex modulates CmMYB121 expression, consequently regulating the tolerance of chrysanthemum to salt. The findings shed light on the responses of plants to salt stress.
