Genome-wide identification and localization of chalcone synthase family in soybean (Glycine max [L]Merr).

Overall, we have identified 21 GmCHS loci with 14 unique GmCHS genes in the soybean genome. Their gene structures and genomic organization together with the spatio-temporal expression and protein localization suggest their importance in the production of downstream metabolites such as (iso)flavonoids and their derived phytoalexins.
