The invention discloses a key gene AaMYB114 closely linked with the color character of an actinidia arguta fruit and application of the key gene AaMYB114. The AaMYB114 gene disclosed by the invention is positioned at 5237694-5239966bp of a chromosome 9 of an actinidia arguta genome, and the full length of the AaMYB114 gene is 2273bp. According to the application, all-red type and all-green type actinidia arguta are used as materials for transcriptome sequencing, and the gene AaMYB114 related to the formation of the peel color of the actinidia arguta is explored. Instantaneous conversion of the actinidia arguta fruit proves that the overexpression of the AaMYB114 increases the anthocyanin content in the actinidia arguta peel. Yeast one-hybridization and dual-luciferase report tests prove that the AaMYB114 not only interacts with a promoter of AaGST, activates the expression of the promoter and regulates anthocyanin transport of peel tissues of actinidia arguta, but also is combined with promoters of anthocyanin synthesis structural genes AaPAL, AaCHI and AaF3H and activates the expression of the promoters to promote anthocyanin synthesis. Therefore, the AaMYB114 gene plays a dual regulation and control role in the formation of peel color and luster, and can be used for cultivating red-peel actinidia arguta.
