摘要
Abiotic and biotic stresses affect plant physiology and growth. The development of metabolomics, along with other -omics technologies, allowed in depth analysis of the reactive processes characterizing plant stress as the result of the alteration of metabolites and gene expressions. Here, we organize and interpret data from 151 studies to provide an overview about metabolomic shift after exposure to either abiotic or biotic stresses including drought, salinity, heat, heavy metal, cold, pathogens and insects. Data showed that amino acids, organic acids, sugars, and sugar alcohols quantities are influenced by stresses. Proline for example, increased in almost every stress condition, while other molecules increased or decreased depending specifically on plant tissue, plant species and type of applied stress. We concluded that although it is difficult to predict precisely what a stress will cause, some general metabolic trends can be described and improve our understanding of plant response to biotic and abiotic stresses.
