Fig. 3 in Glycine max (L.) Merr. (Soybean) metabolome responses to potassium availability

Fig. 3. Complete feature-based molecular network (FBMN) in global natural product social molecular networking (GNPS) of soybean trifoliate leaves and pod tissues, influenced by K+ availability. Nodes represent MS2 spectra and are connected based on spectral similarity defined (cosine score ≥ 0.8), matched fragment ion (5), and network TopK (10), encompassing 902 nodes and 1430 edges organised in 89 spectral molecular families. Large coloured nodes represent metabolites influ- enced by K+ nutrition identified by chemometrics models and representative chemical ontology.
