|a Despite the tangible benefits of copper nanoparticles (CuNPs) for plants, the increasing use of CuNPs poses a threat to plants and the environment. Although miRNAs have been shown to mediate heat shock and CuNPs by altering gene expression, no study has investigated how CuNPs in combination with heat shock (HS) affect the miRNA expression profile. Here, we exposed tomato plants to 0.01 CuONPs at 42 °C for 1 h after exposure. It was found that the expression levels of miR156a, miR159a and miR172a and their targets SPL3, MYB33 and AP2a were altered under CuNPs and HS + CuNPs. This alteration accelerated the change of vegetative phase and the process of leaf senescence. The overexpression of miR393 under CuNPs and HS + CuNPs could also be an indicator of the attenuation of leaf morphology. Interestingly, the down-regulation of Cu/ZnSOD1 and Cu/ZnSOD2 as target genes of miR398a, which showed strong abnormal expression, was replaced by FeSOD (FSD1), indicating the influence of CuNPs. In addition, CuNPs triggered the expression of some important genes of heat shock response, including HsFA2, HSP70-9 and HSP90-3, which showed lower expression compared to HS. Thus, CuNPs play an important role in altering the gene expression pathway during heat stress
