Chalcone synthase (CHS; EC, the first committed enzyme of the multibranched pathway of flavonoid/isoflavonoid biosynthesis is encoded by a multigene family in soybean, (Glycine max L. Merrill). Our results suggest that this gene family comprises at least seven members, some of which are clustered. We have identified four chs clusters in the allo-tetraploid G. max genome and chs5, a newly characterized member of the chs gene family is present in two of them. We describe the complete nucleotide sequence of chs5, the identification of its immediate neighbors and the organization of the four hitherto identified chs clusters in the Gm genome.
