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.

摘要

查尔酮合酶（CHS）催化类黄酮生物合成的第一步和关键调控步骤。我们报道了存在于地下三叶草栽培品种卡里代尔中的一个CHS多基因家族，并对其进行了表征。该CHS家族至少由四个成员组成，它们紧密聚集在一个15kb的区域内。本文给出了其中两个基因（CHS1和CHS2）的完整序列。这些基因的推定启动子具有与已知或涉及苯丙烷类编码基因表达调控的序列同源的序列。
