Fig. 5From: The transcriptome variations of Panaxnotoginseng roots treated with different forms of nitrogen fertilizersThe contents of some metabolites associated with TCA metabolic pathway in P. notoginseng roots under different forms of nitrogen treatments. All values shown are mean values ± standard errors (S.E.). The asterisks indicate significant differences compared with the 15A treatment under the same treatment conditions (Student’s t-test). Standard deviations were calculated from three technical replicates. The results shown were reproduced with three biological replicates. * represents P-values <0.05; ** represents P-values <0.01; *** represents P-values <0.001. a Effects of the different forms of nitrogen treatments on changes of organic acids in TCA cycle of P. notoginseng. b The changes of organic acid synthases in TCA cycle. c The changes of major sugar compounds in TCA cycle. d The NH 4 + content in TCA cycleBack to article page
