Metabolomic profiling of non-model plants as a tool to investigate plant-environment interactions

Phytochemicals play critical roles in diverse physiological and pathological processes by participating in biological reactions that are necessary for proper biological functions and plant environment interactions. Under increasingly stressful conditions, plants experience progressively more impaired cellular and whole-plant processes until the limiting conditions for survival are reached. In brief, plants respond to environmental conditions with changes in the pattern of expression of genes that encode proteins that furthermore control the biosynthesis of metabolites involved in interactions between a given plant and its environment. Phytochemicals present in the plants which are more resistant to the unpleasant environmental condition may help us in the explanation of the processes how plants can cope with situation such as climate changes. Therefore, metabolomics as an important sector of post-genome science can show us how plants respond to environment. In the present work we will show metabolomic data (GC-MS, LC-QToF and MALDI Imaging) for two non-model plants which are attributed with good adaptation to environmental condition. First is early whisk fern Psilotum nudum (L.) P. Beauv or so called "living fossils" whose metabolic processes could help in understanding plant adaptations through evolution. Second plant is kale (Brassica oleracea L. var. acephala), which is highly resistant to low temperature and whose metabolite profile could help us in the understanding the molecular mechanisms contributing to the plant's low temperature tolerance.
