| Study Title | Untargeted MS-based metabolomics analysis of the responses to drought stress in Quercus ilex leaf seedlings, and identification of putative compounds related to tolerance |
| Study Type | Untargeted MS-based metabolomics |
| Study Summary | The effect and responses to drought stress have been analyzed in Quercus ilex seedlings by using a non-targeted metabolomic approach, implementing previous studies pub-lished in which other -omics platforms, transcriptomics, and proteomics, have been em-ployed. This work is aimed at characterizing the Q. ilex leaf metabolome, determining possible mechanisms and molecular markers of drought tolerance, and identifying puta-tive bioactive compounds. Six-month-old seedling leaves, subjected to drought stress im-posed by water withholding under high temperature and irradiance conditions, were col-lected when leaf fluorescence decreased by 20 % (day 17) and 45 % (day 24) relative to ir-rigated seedlings. A total of 3934 compounds were resolved, with 616 being variable, and 342 identified, belonging to five chemical families. Out of the identified compounds 33 were variable, mostly corresponding to amino acids, carboxylic acids, benzenoids, flavo-noids and isoprenoids. Epigallocatechin, ellagic acid, pulegone, indole-3-acrylic acid and dihydrozeatin-O-glucoside were up-accumulated under drought conditions at both sam-pling times. An integrated multi-omics analysis of phenolic compounds and related en-zymes was performed, revealing that some enzymes involved in the flavonoid pathways (chalcone synthase, anthocyanidin synthase and anthocyanidin reductase) were up-accumulated at day 24 in non-irrigated seedlings. Some putative markers of drought tol-erance to drought in Q. ilex are proposed for assisting breeding programs based on the se-lection of elite genotypes. |
