Exudates are made up of a large variety of compounds, the composition of which is known to differ depending on many biotic and abiotic factors. One such factor is water availability, which is relevant as drought is becoming a significant problem in many areas of the world. Metabolomics techniques were used to closely monitor changes in root exudate composition from Quercus ilex plants in experimental drought conditions and the subsequent recovery. Of the 601 metabolites that were detected, 63 were identified, and amino acids, carbohydrates, and organic acids were the most abundant compound groups. Overall, drought stress had a strong effect on the composition of root exudate metabolites. The metabolic profiles of drought-stressed plants mainly consisted of secondary metabolites, whereas exudate metabolites in recovery plants were predominantly primary metabolites. The composition of exudates in recovery differed depending on the previous drought intensity, and those in the most extreme drought treatment showed a lack of recovery. A better understanding of the compounds that are found in root exudates of plants before, during, and after drought events of different intensities, will be important for predicting drought impacts across soils in many different ecosystems.
