The invention discloses a festuca arundinacea transcription factor FaNAC047 for regulating and controlling high-temperature induced leaf aging and application of the festuca arundinacea transcription factor FaNAC047, and belongs to the field of gene engineering. According to the invention, a gene FaNAC047 which is obviously induced by high temperature and aging is cloned from festuca arundinacea, the open reading frame (ORF) of the gene FaNAC047 is 966bp, and the gene FaNAC047 is as shown in SEQ NO. 1, codes 321 amino acids, and is as shown in SEQ ID NO. 2. According to the present invention, the overexpression of the FaNAC047 in the festuca arundinacea accelerates the high temperature induced leaf senescence, and the down-regulation of the expression of the endogenous FaNAC047 of the festuca arundinacea through the RNA interference technology (RNAi) delays the high temperature induced leaf senescence, such that the FaNAC047 can positively regulate the high temperature induced leaf senescence; the FaNAC047 ge
