Notably, the regulatory scope of ethylene-MYB modules extends beyond cell wall restructuring to the modulation of fruit nutritional quality. In mango fruit, ethylene exerts bidirectional transcriptional control over two MYB isoforms: it significantly upregulates Mi MYB1 R1-like while downregulating Mi MYB44-like, and this differential response of the two MYB factors collectively mediates ethylene-modulated ascorbic acid (As A) metabolism during fruit ripening
