This study used metabolite analysis and profiling to examine how Arabidopsis thaliana responds to cold stress and the impacts of thermo tolerance. Many metabolites (14) were examined using gas chromatography-mass spectrometry. The majority of plant metabolomics investigations employ this methodology. The samples were subjected to several studies, including PCA analysis, which examined the effects of low temperatures on both the experimental and control groups.
Under cold stress, Arabidopsis thaliana's metabolism has changed significantly as compared to the control group. The concentration of several metabolites, such as proline, valine, glycine, succinate, trehalose, sucrose, myo-inositol, glutamine, and others, is correlated with the presence of stress.
Future experiments to determine whether a promising engineering metabolic may be utilized to boost the stress resistance of physiologically and commercially significant plants can benefit from this technique. It is challenging to rearrange the metabolic network because of the rapid reaction to stress and cold that raises the level of the mentioned specific metabolites (p-value 0.1). These metabolite investigations may serve as essential targets for stress-tolerant plants' metabolic engineering.
