Cloning and tissue stress of γ - glutamyl transpeptidase gene in A study of differences in expression
Abstract：The GGT1 and GGT3 genes were obtained from the "Huangjinya" by PCR, and the CsGGT1 and CsGGT3 genes contained 1801 and 1861 bp open reading frames, encoding 599 and 619 amino acids, respectively. The results showed that most of the amino acids were hydrophilic amino acids and the disorder characteristics were obvious. The results of real-time fluorescence quantitative PCR showed that the amino acids were not sensitive to the amino acids, There were significant differences in the expression of GGT1 and GGT3 genes in tea leaves, and the expression level of GGT1 and GGT3 in tea leaves was the highest in the 3rd leaf, and the expression level of GGT1 and GGT3 was the highest among the three cultivars. GGT1 and GGT3 were induced by high temperature and low temperature. Which GGT1 in low temperature, high temperature are inhibited. GGT3 increased at low temperature and inhibited at high temperature. Indicating that GGT gene plays an important role in the regulation of tea plant temperature stress.
