Findings reveal that auxin and ethylene facilitate ripening and transcription factor expression in bananas, suggesting a regulatory role for MaIAA1-like and MaERF003.
Key Points
Ripening is enhanced by auxin and ethylene, while 1-methylcyclopropene suppresses this process, highlighting the importance of these regulators.
Key transcription factors MaIAA1-like and MaERF003 were identified as mediators of crosstalk between auxin and ethylene during fruit ripening.
Transient expression studies confirmed that overexpressing MaIAA1-like and MaERF003 accelerates softening and de-greening in bananas.
These findings emphasize the regulatory role of the MaIAA1-like-MaERF003 module in fruit ripening and suggest potential agricultural applications.
