title: Leaf Flavonoid Glycosylation and Sprout Morphogenesis in Silene pratensis Influenced by the Spectral Composition of Light.
abstract: Seedlings of a mutant of Silene pratensis contain isovitexin 7-O-galactoside 6-O″-arabinoside in the rosette-type leaves but not in the sessile stem leaves. Just around the phase of transition from rosette to flower stem this compound is replaced by isovitexin. Changes in light quality strongly influence both the transition phase in plant development and the transition in flavone composition. A regulation of both processes by the same photoreceptor, presumably phytochrome, is indicated.
