Transcription factor SmMYB12, application thereof and protein

The invention relates to a transcription factor SmMYB12 cloned from eggplant, application of the transcription factor SmMYB12 in regulation and control of the flavonoid content of eggplant peel, and a protein of the transcription factor SmMYB12. The maximum reading frame sequence of the transcription factor SmMYB12 is represented by SEQ ID NO.1, and the amino acid sequence coded by the transcription factor SmMYB12 is represented by SEQ ID NO.2. The eggplant is transformed by adopting an agrobacterium tumefaciens-mediated method, and the result proves that compared with a non-transformed plant, the flavonoid content of a transgenic eggplant plant is obviously increased, so that the peel color becomes light. The method is beneficial to further understanding the eggplant peel coloring mechanism, so that the eggplant peel coloring can be regulated and controlled by utilizing a molecular means, and a new eggplant variety with better coloring is bred. 本发明涉及一种从茄子中克隆得到的转录因子SmMYB12，及其在调控茄子果皮类黄酮含量中的应用和蛋白质。所述转录因子SmMYB12
