| Abstract: |
| To investigate the effects of ACC deaminase bacteria under saline stress on the lipid metabolism of mung bean leaves, liquid chromatography mass spectrometry was used to analyze the changes of lipid metabolites in the leaves of ACC (DQJC1). It was found that DQJC1 inoculation under saline stress promoted the growth of mung bean, which significantly increased the plant height (34.87%), aboveground parts fresh weight (44.07% and 46.43%), underground partsdry weightof mung bean plants (30.56% and 23.68%) in the chlorophyll content (41.61%). At the same time, 61 metabolites with significant differences (P<0.05) were selected, including 32 glycerophospholipids, 14 sterols, 4 glycerol lipids, 3 sphingolipids and 8 other lipids. The upregulated metabolites were glycerol phospholipids (PC, PG, LPC, PI, PE, LPG), glycerol lipids (SQDG47∶11) and sphingolipids (CerG1d18∶2/16∶0+O).The upregulated metabolites were mainly sterols (TG); glycerol glucolipids (SQDG∶16∶0/16∶0) and sphingolipids (CerG1d34∶2+O). KEGG pathway enrichment analysis found that six of the selected differential metabolites were enriched in 9 metabolic pathways, including glycerophospholipid metabolism pathway,glycerol lipid metabolismpathway,autophagy\|other pathway, glycosylphosphatidylinositol (GPI)\|anchor biosynthesispathway, ether lipid metabolismpathway, linoleic acid metabolismpathway, phosphatidylinositol signaling systempathway, alpha\|linolenic acid metabolismpathway and arachidonic acid metabolism pathway. |
