Induction de la synthèse de la δ-aminolévulinate déshydratase des cotylédons de radis étiolés ou cultivés sous lumière rouge lointain par l'érythromycine

Abstract

Erythromycin stimulates the de novo synthesis of δ-aminolevulinate dehydratase of radish cotyledons in both far-red light and darkness and blocks the enzyme accumulation in the etioplast. Density labelling experiments using erythromycin and cycloheximide demonstrate that δ-aminolevulinate dehydratase is encoded by the nuclear genome and that its synthesis is controlled by the etioplast.
