Gene Details:

Functional Descriptions:

  • The transcription factor CmERFI-2 represses CmMYB44 expression to increase sucrose levels in oriental melon fruit.
  • During the later stages of fruit ripening, the repressive effect of CmMYB44 on CmSPS1 and CmACO1 could be released by overexpressing CmERFI-2 (ethylene response factor I-2) and exogenous ethylene in “HS” fruit (high sucrose accumulation fruit).
  • CmERFI-2 acted upstream of CmMYB44 as a repressor by directly binding the CmMYB44 promoter region, indirectly stimulating the expression level of CmSPS1 and CmACO1.
  • With fruit ripening, the highly expressed CmERFI-2 reversed its repressive effect on CmSPS1 and CmACO1, ultimately resulting in sucrose accumulation and ethylene synthesis during the ripening stages.
