Metabolomics Role in Crop Improvement

Saleha Resham, Fizza Akhter, Muhammad Ashraf and Alvina Gul Kazi

Metabolomics as first described in 1998 is the study of all low-molecular-mass compounds synthesized and modified by a living cell or organism. Metabolic profiling (metabolomics/metabonomics) is the measurement in biological systems of the complement of low-molecular-weight metabolites and their intermediates that reflects the dynamic response to genetic modification and physiological, pathophysiological, and developmental stimuli. It involves the application of the combination of fields like analytical biochemistry, informatics, bioinformatics, and statistics for measuring metabolic products of living systems. Nuclear magnetic resonance ...
