Lycoris radiata LlMYB4 gene as well as encoding protein and application thereof

The invention discloses a lycoris radiata LlMYB4 gene as well as an encoding protein and application thereof, and belongs to the technical field of plant molecular biology. The nucleotide sequence of the lycoris radiata LlMYB4 gene disclosed by the invention is as shown in SEQ ID NO. 1, and the amino acid sequence of the lycoris radiata LlMYB4 gene is as shown in SEQ ID NO. 2. The method comprises the following steps: by taking a floral sheet of lycoris radiata in a full-bloom stage as a material, cloning to obtain a lycoris radiata LIMYB4 gene, constructing an overexpression vector Super1300-L1MYB4 on the basis, and transferring the overexpression vector Super1300-L1MYB4 into a Bensi tobacco leaf to obtain a transgenic plant; a gene function identification result shows that the lycoris longtube LlMYB4 gene is an important transcription factor for inhibiting anthocyanin synthesis or promoting anthocyanin degradation, and has a good application prospect in the aspects of plant growth and development and breedi
