Gene Details:

  • Gene ID: Ma04_g00460.1
  • Gene Symbol: MaMYB60
  • Gene Name: Musa acuminata
  • Genome:
  • Species: Musa acuminata

Functional Descriptions:

  • Proteasomal degradation of MaMYB60 mediated by the E3 ligase MaBAH1 causes high temperature-induced repression of chlorophyll catabolism and green ripening in banana.
  • Identified a MYB transcription factor, MaMYB60, that activated the expression of all 5 CCGs by directly binding to their promoters during banana ripening at 20 °C, while showing a weaker activation at 30 °C.
  • MaBAH1 thus facilitated MaMYB60 degradation and attenuated MaMYB60-induced transactivation of CCGs and chlorophyll degradation.
  • By contrast, MaMYB60 upregulation increased CCG expression, accelerated chlorophyll degradation, and mitigated green ripening. Collectively, our findings unravel a dynamic, temperature-responsive MaBAH1–MaMYB60–CCG module that regulates chlorophyll catabolism, and the molecular mechanism underpinning green ripening in banana.
