Transcription factor CsHsf24 and application thereof in promoting synthesis regulation of tea tree flavonoid

The invention provides a transcription factor CsHsf24 and application of the transcription factor CsHsf24 in promoting synthesis regulation of tea tree flavonoid. The nucleotide sequence of the transcription factor CsHsf24 is shown as SEQ ID NO.2, and belongs to the technical field of gene engineering. The invention verifies that CsHsf24 is combined with a promoter of flavonoid 3 '5'-hydroxylase through a yeast single miscellaneous point-to-point experiment to activate the expression of a CsF3 '5' H1 gene so as to promote the increase of the contents of substances such as catechin and flavonol. Through verification, the CsHsf24 gene expression of the tea tree and the flavonoid substance content are in a positive correlation relationship. The CsHsf24 gene is overexpressed by adopting a genetic transformation technology, flavonoid accumulation is remarkably promoted, the tea quality is improved, and the CsHsf24 gene can be used as an important candidate gene for developing genetic engineering and improved breed
