Plant Metabolome Analysis

The plant metabolome consists of the complete number of small molecules. It represents the final chemotype of plants, which arises from the gene expression, modulation of protein function and the influence of environmental factors. The tremendous progress in the high-throughput analysis of genes and proteins as well as progress in the targeted (LC-MS and GC-MS) and untargeted Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) analyses of metabolites have created the desire of plant scientists to describe plant behavior in a holistic and comprehensive way.

This project aims to elucidate the influence of various abiotic and biotic stresses on the variability of the metabolome pattern and the network of metabolic fluxes in natural poplar phenotypes and transgenic poplars modified in the isoprenoid metabolism. Finally we will create a metabolome database that combines physiological and phenological effects of stress on plants with the underlying plant metabolome. The project runs jointly with the Research Unit Biogeochemistry
