Juvenile Hormone Titer Versus Juvenile Hormone Synthesis in Female Nymphs and Adults of the German Cockroach, Blattella germanica
Abstract Patterns of juvenile hormone have been intensively studied in the cockroach Blattella germanica under different physiological situations. However, data have been mainly obtained in vitro, and refer to hormone synthesized by isolated corpora allata, whereas information available on hormone concentration in the hemolymph is restricted to adult females. In order to complement our studies ...
متن کاملJuvenile hormone synthesis: "esterify then epoxidize" or "epoxidize then esterify"? Insights from the structural characterization of juvenile hormone acid methyltransferase.
Juvenile hormones (JHs) play key roles in regulating metamorphosis and reproduction in insects. The last two steps of JH synthesis diverge depending on the insect order. In Lepidoptera, epoxidation by a P450 monooxygenase precedes esterification by a juvenile hormone acid methyltransferase (JHAMT). In Orthoptera, Dictyoptera, Coleoptera and Diptera epoxidation follows methylation. The aim of ou...
متن کاملJuvenile hormone acid O-methyltransferase in Drosophila melanogaster.
Juvenile hormone (JH) acid O-methyltransferase (JHAMT) is the enzyme that transfers a methyl group from S-adenosyl-l-methionine (SAM) to the carboxyl group of JH acids to produce active JHs in the corpora allata. While the JHAMT gene was originally identified and characterized in the silkworm Bombyx mori, no orthologs from other insects have been studied until now. Here we report on the functio...

متن کاملJuvenile Hormone in Insects
■ Abstract The mevalonate pathway in insects has two important peculiarities, the absence of the sterol branch and the synthesis of juvenile hormone (JH), that may have influenced the mechanisms of regulation. The data available on these mechanisms indicate that cholesterol does not play a regulatory role and that JH modulates transcript levels of a number of genes of the mevalonate pathway or ...
