Gene bHLH35 for promoting anthocyanin accumulation of plants and application thereof

A method for cultivating transgenic plants having increased anthocyanin content, comprising the following step:

• transferring a bHLH35 gene into recipient plants using a genetic engineering transformation method, to obtain transgenic plants having increased anthocyanin content;
• wherein the bHLH35 gene is selected from the group consisting of:
• a ChbHLH35 gene from Corydalis hemidicentra, wherein the nucleotide sequence of the ChbHLH35 gene is shown in SEQ ID No:
• 1, and the amino acid sequence encoded by the ChbHLH35 gene is shown in SEQ ID No:
• 2;
• or an AtbHLH35 gene from Arabidopsis thaliana wherein the nucleotide sequence of the AtbHLH35 gene is shown in SEQ ID No:
• 3, and the amino acid sequence encoded by the AtbHLH35 gene is shown in SEQ ID No:
• 4.
