Cystathionine-game-synase specific expression sequence label of tea tree and its biologic chip

Specific expressive sequential labels of systathionine-gama-synthetase of tea tree and their biochips are disclosed. The labels are of sequences shown in SEQ ID No.1 - SEQ ID No.2, one or combination of more in the said both sequences, complementary or homologous ones of each, those with 8 - 100 continuous nucleotides as probes or their complementary ones. Two expressive sequential labels of systathionine-gama-synthetase of tea tree are obtained by DNA determining the established library of cDNA of tea tree by expression sequential label technology after taking out surplus sequences, searching databases through Internet. The invention can be used in evaluation of crop seed sources, early prediction of hybrid vigor, research on plant resistance, determination of plant SNP, inspection of transgenic crop security, and screen of herbicides and agro-chemicals, etc.
