|a As a kind of small molecular weight proteins, many peptides have been discovered, including peptides encoded by pri-miRNA (miPEPs). Similar as traditional phytohormone or signaling molecular, these peptides participate in numerous plant growth processes. MicroRNAs (miRNAs) play an important regulatory role in plant stress response. While the roles of miPEPs in response to abiotic stress has not been studied now. In this study, to explore whether miPEPs could contribute to low temperature (4ºC) tolerance of plants, the expression pattern of 23 different vvi-MIRs were analyzed by qRT-PCR in 'Thompson Seedless' (Vitis vinifera) plantlets under cold stress (4ºC) firstly, and vvi-MIR172b and vvi-MIR3635b which showed an elevated expression levels were selected to identify miPEPs. Through transient expression, one small open reading frame (sORF) in each of the two pri-miRNAs could increase the expression of corresponding vvi-MIR, and the amino acid sequences of sORFs were named vvi-miPEP172b and vvi-miPEP3635b, respectively. The synthetic vvi-miPEP172b and vvi-miPEP3635b were applied to the grape plantlets, and the tissue culture plantlets exhibited a higher cold tolerance compared with the control groups. These results revealed the effective roles of miPEPs in plant cold stress resistance for the first time, providing a theoretical basis for the future application of miPEPs to agricultural production
