Post-Harvest Application of Nanoparticles of Titanium Dioxide (NPs-TiO₂) and Ethylene to Improve the Coloration of Detached Apple Fruit.

ABSTRACT: In this study, we analyzed the effects of treatments with titanium dioxide nanoparticles (NPs-TiO₂) and ethylene on anthocyanin biosynthesis and reactive oxygen species (ROS) metabolism during light exposure in ripe 'red delicious' apples. Both treatments led to improved anthocyanins biosynthesis in detached mature apples, while the NPs-TiO₂ had less impact on the fruit firmness, TSS, TA, and TSS/TA ratio. Furthermore, the effects of both treatments on the expression of anthocyanin-related enzymes and transcription factors in the apple peel were evaluated at the gene level. The differentially expressed genes induced by the two treatments were highly enriched in the photosynthesis and flavonoid biosynthesis pathways. The expression of structural genes involved in antho
