外源水杨酸干预高钙胁迫下苍术差异代谢物的分析OACSTPCD

In this study,metabolomics was further used to screen differential metabolites in Atractylodes rhizo-ma under high calcium(Ca)stress intervention with exogenous salicylic acid.Results showed that there were 55 metabolites showing significant differences between the high calcium stress group and control group,inclu-ding 26 up-regulated and 29 down-regulated metabolites,mainly lipids.There were 38 metabolites showing significant differences between the the high calcium stress group interventing with salicylic acid and the high calcium stress group,including 26 up-regulated and 12 down-regulated metabolites,mainly lipids and carbo-hydrates.HCA analysis showed that the content of some metabolites,such as d-Desthiobiotin,Isogerma-furene,Hericenone C,11-Deacetylvaltrate 11-(3-hydroxy-3-methylbutanoate),9,10-DHOME,13(S)-HPOT,Nap-Asn-OH,Myristoylglycine,Glabrin C,increased or decreased under high calcium stress and the content partially recovered after salicylic acid intervention,indicating that exogenous salicylic acid could effec-tively alleviate the effect of high calcium stress to the metabolism of A.rhizoma.
