The invention discloses a swallow flower MYB4 protein and application thereof in flower color regulation and control, and belongs to the technical field of plant gene engineering. The invention discloses swallow flower MYB4 gene cloning, plant overexpression vector construction and an application method in flower color regulation and control. The amino acid sequence of the swallow flower MYB4 protein is as shown in SEQ ID No. 1, and the nucleotide sequence for coding the protein is as shown in SEQ ID No. 2. It is found for the first time that through overexpression of the swallow MYB4 gene in tobacco, the content of anthocyanin in corolla of tobacco can be reduced, and the color can be whitened. The crassula vinosa MYB4 protein provided by the invention provides a theoretical reference for researching the regulation and control of the flower color of crassula vinosa, and further provides an important gene resource for the flower color breeding work in the future.
