Abstract

The flavonoids of two diploid species of Phlox and two of their allotetraploid derivatives were characterized. The tetraploids accumulate five flavonoids not observed in the parental species. Generally, novel compounds are less highly glycosidated than, but otherwise similar to, parental compounds that they partially or totally replace. We propose that hybridity and polyploidy have repressed or suppressed the activity of certain ancestral genes responsible for the production of glycosidating enzymes. Accordingly, the novel compounds are merely the accumulated or modified precursors of parental compounds.

摘要

对福禄考属两个二倍体物种及其两个异源四倍体衍生物的类黄酮进行了表征。四倍体积累了五种在亲本物种中未观察到的类黄酮。一般来说,新化合物的糖基化程度低于它们部分或完全取代的亲本化合物,但在其他方面与亲本化合物相似。我们提出,杂交和多倍体抑制或压制了某些负责糖基化酶产生的祖先基因的活性。因此,新化合物仅仅是亲本化合物积累或修饰后的前体。
