title: In Trifolium subterraneum, chalcone synthase is encoded by a multigene family.
abstract: Chalcone synthase (CHS) catalyzes the first and key regulatory step in flavonoid biosynthesis. We report the existence and characterization of a CHS multigene family present in Trifolium subterraneum L. cultivar Karridale. The CHS family consists of at least four members, which are tightly clustered in a 15-kb region. The complete sequences of two of these genes (CHS1 and CHS2) are presented. The putative promoters of these genes have sequences which are homologous to those known, or implicated, in regulation of the expression of phenylpropanoid-encoding genes.
