Abstract:
The leaves of Platycodon grandiflorum were used as experimental materials,and polyethylene glycol (PEG) was used to simulate drought stress,widely-targeted metabolomics ultra-performance liquid chromatography-mass spectrometry(UPLC-MS/MS) was used to detected metabolites of drought stress group（P1） and control group（CK）,to investigate the metabolic response of Platycodon grandiflorus to drought stress.Multivariate statistical analysis coupled with univariate statistical analysis were used,in order to provide reference for the breeding of drought-resistant Platycodon grandiflorus.The results showed that there were 632 metabolites and 78 differential metabolites after drought stress were detected,66 of which were up-regulated and 12 were down-regulated.Differential metabolites were mainly concentrated in amino acids and their derivatives,lipids,organic acids and their derivatives,nucleotides and their derivatives.KEGG enrichment analysis showed that the significantly pathways were aminoayl-tRNA biosynthesis,2-oxocarboxylic acid metabolism and biosynthesis of amino acids.The changes of metabolites in the Platycodon grandiflorus leaves under drought stress were elucidated.Amino acid and lipid related metabolites were the main products of Platycodon grandiflorus responsed to drought stress.
