| Study Title | Evaluation of the short-term effects of the allelochemical umbelliferone on Triticum durum L. metabolism through GC-MS based untargeted metabolomics |
| Study Summary | Allelopathy is a plant defense mechanism by which they protect themselves from competitive species using specialized biochemicals in the form of secretion or volatiles released to the environment. Though, umbelliferone is a well-known allelochemical, its mechanism of action in a short-term treatment is far from established. We used ≈ 10–days old wheat seedlings treated with104 µM umbelliferone over a time course experiment covering 6 times points, i.e., 0h, 6h, 12h, 24h, 48h, and 96h and compared the metabolomic changes to control (mock-treated) plants. Using gas chromatography mass-spectrometry (GC-MS) based metabolomics efforts, we collectively obtained quantitative data on 177 metabolites that were derivatized (either derivatized singly or multiple times) or not representing 139 non-redundant (unique) metabolites. Out of these 139 metabolites, 118 were associated with a unique HMDB identifier, while 113 were associated with a KEGG identifier. Relative quantification of these metabolites across the time-course of umbelliferone treatment, revealed 22 compounds (sugars, fatty acids, secondary metabolites, organic acids, and amino acids) that changed significantly (repeated measures ANOVA, P-value < 0.05) with time. Using multivariate partial least squares discriminant analysis (PLS-DA) we showed the grouping of samples based on time-course across the control and umbelliferone treated plants, whereas the metabolite-metabolite Pearson correlation revealed tightly formed clusters of umbelliferone-derived metabolites, fatty acids, amino acids, and carbohydrates. Also, time-course of umbelliferone treatment revealed, that phospho-L-serine, maltose, and dehydroquinic acid were the top three metabolites showing highest importance in discrimination among the time-points. The above indicate a system-wide changes induced by umbelliferone, through dysregulation of primary as well as specialized metabolism. |
