Metabolic analyses are a useful tool for the comprehensive identification of plant defense response metabolites. In this study, a gas chromatography-mass spectrometry (GC-MS) approach was used to identify metabolites differences in tobacco xylem sap in response to <i>R. pseudosolanacearum</i> CQPS-1 in two tobacco cultivars: Yunyan87 (susceptible to <i>R. pseudosolanacearum</i>) and K326 (quantitatively resistant). Metabolite profiling 7 days post inoculation with <i>R. pseudosolanacearum</i> identified 88 known compounds, 42 of them enriched and 6 depleted in the susceptible cultivar Yunyan87, while almost no changes occurred in quantitatively resistantFrontiers in plant science780429https://www.ebi.ac.uk/biostudies/studies/S-EPMC8780990biostudies-literatureMetabolic Profiling of Resistant and Susceptible Tobaccos Response Incited by <i>Ralstonia pseudosolanacearum</i> Causing Bacterial Wilt.PMC8780990Ding WYang LValls MWei ZfalseMetabolic Profiling of Resistant and Susceptible Tobaccos Response Incited by <i>Ralstonia pseudosolanacearum</i> Causing Bacterial Wilt.The causal agent of bacterial wilt, <i>Ralstonia pseudosolanacearum</i>, can cause significant economic losses during tobacco production.
