Abstract
The metabolome of three soybean genotypes, Glycine max Hwangkeum (elite or domesticated cultivar), Glycine max Napjakong (landrace or semi-wild cultivar) and Glycine soja Dolkong (wild cultivar), were characterized in seeds and leaves using a 1H NMR-based metabolomics approach. Expression of primary and secondary metabolites were different in seeds and leaves as well as amongst soybean genotypes. Different kaempferol glycosides were observed in the leaves but not in the seeds, and quercetin derivatives were found only in G. max Napjakong and G. soja Dolkong. Moreover, epicatechin was found only in the seeds of G. max Napjakong and G. soja Dolkong. These results demonstrate distinct adaptations of different soybean genotypes to given environmental conditions. The current study, therefore, provides useful information on global metabolic compositions that might be used to develop soybean-based products through better understanding of the metabolic phenotypes of existing soybean genotypes.
