Application of CsGATA2 gene in regulation and control of synthesis of theanine and / or ethylamine of tea tree
By regulating the expression of the CsGATA2 gene and combining it with the CsAlaDC gene promoter, the problem of inhibited theanine synthesis in tea trees was solved, the synthesis of theanine and ethylamine was increased, and the growth and stress resistance of tea trees were enhanced.

Abstract
The invention belongs to the technical field of plant genetic engineering, and particularly relates to application of a CsGATA2 gene in regulation and control of synthesis of theanine and / or ethylamine of a tea tree. The CsGATA2 transcription factor highly responding to temperature change is excavated by taking cutting seedlings of an annual tea tree variety Shuchazao as experimental materials through four kinds of temperature treatment, a molecular mechanism that the CsGATA2 transcription factor participates in regulation and control of theanine metabolism of a tea tree is proved through in-vivo and in-vitro tests of the tea tree, the CsGATA2 gene is determined to be a target gene for synthesizing theanine, and the CsGATA2 transcription factor is a CsGATA2 gene for synthesizing theanine. The CsGATA2 gene can respond to temperature treatment, and the content of theanine synthesis precursor substance ethylamine is increased by activating the transcriptional activity of CsAlaDC in a tea tree body, so that the content of theanine is increased.
