Abstract: Glutathione S-transferases (GSTs) belong to a superfamily of multifunctional enzymes and are ubiquitous in plants. Forty nine CsGSTs genes were identified by transcriptome analysis of Zhonghuang 2 and Longjing 43 under control and shading treatment. Nineteen CsGSTs with relatively high expression levels in buds were used for sequence and phylogenetic tree analysis. Real-time fluorescence quantitative PCR (qRT-PCR) was performed to analyze the expression patterns of 8 candidate genes in different leaf positions of Longjing 43. The results showed that CsGSTs were expressed in all tested leaves, but exhibited different expression patterns. CsGST20 showed an increasing expression from a bud with a leaf to the sixth leaf, suggesting a potential role in stress resistance. On the other hand, the expression level of CsGST24 dropped significantly, suggesting that CsGST24 might participate in anthocyanin accumulation in tea plants.
