AI Technical Summary
In the existing technology, the postharvest ripening process of banana fruit is difficult to control effectively, leading to fruit softening and rotting, resulting in significant postharvest losses. Furthermore, the function and molecular mechanism of the SBP family in the regulation of banana fruit ripening have not been fully studied.
The function of the MaSBP17 gene in banana was identified and verified. The MaSBP17 gene was silenced by virus-induced gene silencing (VIGS) technology, which affected the content of reactive oxygen species (ROS) and cell wall metabolism in the fruit, thereby regulating the fruit ripening process.
Silencing the MaSBP17 gene resulted in bananas exhibiting an early-ripening phenotype, decreased fruit firmness, increased ROS content, and soluble sugar accumulation. This provides a theoretical basis and molecular target for targeted regulation of fruit ripening, delaying softening and senescence, and has scientific value and application prospects.
