Expression and regulation of the shikimic acid pathway gene DHD/SDH in tea plant (Camellia sinensis)北大核心CSCD

3-Dehydroquinic acid dehydrase/shikimate dehydrogenase (DHD/SDH) is the only bifunctional enzyme in the shikimic acid pathway. It can catalyze the generation of shikimic acid and gallic acid. To investigate the expression and regulation patterns of DHD/SDH in tea, we aimed to determine (1) the miRNA-mediated cleavage of DHD/SDH involved in the shikimic acid pathway, (2) the expression pattern of miRNA and their targets, and (3) the expression pattern of three DHD/SDH genes in tea plant (Camellia sinensis) with different hormone treatments via online prediction, RLM-RACE, and qPCR. Based on the miRNAs obtained, we identified four miRNAs that regulated CsDHD/SDH in tea. CsDHD/SDH2 was targeted by miR5180b, miR1510b-5p, and miR24; CsDHD/SDH3 was targeted by miR868-5p. We also found that CsDHD/SDH2 and CsDHD/SDH3 have a similar expression pattern under different hormone treatments, and they were synergistic with each other. CsDHD/SDH1 exhibited an expression pattern opposite to that of the other two homologues, and increased expression of CsDHD/SDH1 reduced the expression of the other two genes. © 2018 Science Press.
