Plants produce hundreds of Specialized Metabolites (SMs) in different plant tissues and organs, particularly in seeds that accumulate large amount of various SM classes. These SMs play a crucial role on physiological functions protecting seeds from a wide range of abiotic and biotic stresses. Nevertheless, despite the essential role of SMs in the interaction of plants with their environment, studying the ability of seeds to produce these protective compounds has been neglected. In our team, we use untargeted metabolomics to study SM landscapes in the seeds of different Brassicaceae species and accessions/varieties (e.g. Camelina and Arabidopsis) grown in the open field and harvested during several consecutive growing seasons, or grown in controlled conditions and subjected to abiotic and biotic stresses. I will present data showing major and unexplored effects of the environment on the stimulation of the seed specialized metabolome suggesting that, contrary to what is thought, seeds may not be exclusively storage and “metabolically static” organs, but they show a very dynamic and inducible metabolism. Our work suggests a predominant effect of the environment on the regulation of the seed-specialized metabolome, with a potential impact on the seed quality of Brassicaceae species.
