Castor Bean Metabolomics: Current Knowledge and Perspectives Toward Understanding of Plant Plasticity Under Stress Condition
Metabolomics provides vital information for the understanding of biological processes and has been vastly applied in plant studies. Several metabolite-profiling studies have correlated physiological events, such as germination or seedling establishment, with metabolic and molecular changes under different environmental conditions. Castor bean displays high plasticity during initial vegetative growth, which is reflected in the metabolome of the seeds and seedlings. In general, several metabolite-profiling techniques are required to obtain a complete response in terms of metabolism plasticity of the studied biological system. Carbohydrates, amino acids, and organic acids have been measured in castor bean seeds and seedlings by nuclear magnetic resonance, gas chromatography coupled to a quadrupole time of flight mass spectrometry (GC-TOF-MS), as well as by high-performance liquid chromatography (HPLC). Fatty acids and some secondary metabolites have been quantified in castor bean seeds and seedlings by gas chromatography coupled to a triple-axis detector (GC-MS). In this chapter, we initially discuss how metabolomics studies suggested a possible role of gamma-aminobutyric acid (GABA) accumulation during early imbibitions and seedling establishment. Later, we consider a specific metabolic signature of castor bean: a shift in carbonânitrogen metabolism as its main biochemical response to high temperatures. This metabolic shift is usually associated with adjusted growth, and it is likely involved in maintaining cellular homeostasis under heat stress. The castor bean metabolome has been vastly investigated, especially with regard to its ability to respond to external stimuli. These results might help us understand the molecular requirements for vigorous castor bean seed germination and seedling growth under different environmental conditions
