Juvenile Hormone Induced Biosynthesis of Vitellogenin in Leucophaea maderae from Large Precursor Polypeptides

Despite the extensive research in recent years on insect juvenile hormone (JH), its mode of action at the molecular level is still not understood. One reason for this gap in our knowledge is that the usual morphological assays of JH action do not lend themselves readily to analysis by molecular biological tools. For this reason, we have chosen to study the mode of action of JH in a system which, although lacking in morphogenetic changes, is nevertheless amenable to biochemical analysis. In this approach, we assume that the mechanisms of action we may discover in this system will be equally applicable to JH-regulated morphogenetic processes, but of course this remains to be proven.
