Selection of suitable inner reference genes for normalisation of microRNA expression response to abiotic stresses by RT-qPCR in leaves, flowers and young stems of peach.

Highlights: [•] This is the first report on reference genes of miRNA RT-qPCR in peach. [•] Gene expression stability of 17 reference genes was evaluated. [•] The combination of miR5059 and miR5072 was identified as the best reference genes. [•] The miR396 and miR5072 pair was suitable for different tissues sets in peach. [Copyright &y& Elsevier]
