Biosynthetic pathway of insect juvenile hormone III in cell suspension cultures of the sedge Cyperus iria.
In most insect species, juvenile hormones regulate critical physiological processes such as metamorphosis and reproduction. In insects, these sesquiterpenoids are synthesized by retrocerebral endocrine organs, the corpora allata, via the classical mevalonate (MVA) pathway. One of these compounds, juvenile hormone III (JH III), has also been identified in the sedge Cyperus iria. In higher plants...
متن کاملThe lethal effects of Cyperus iria on Aedes aegypti.
The sedge Cyperus iria, a common weed in rice, contains large amounts of the insect hormone (10R) juvenile hormone III (JH III). Given its widespread distribution in Asia and Africa, we examined the possibility that C. iria could be used as a safe, inexpensive, and readily available mosquito larvicide. Plants of varying ages were harvested and leaves tested for lethal effects on larvae of the y...
متن کاملThe Inhibitory Effect of Grasshopper's Cyperus (Cyperus iria L.) on the Seedling Growth of Five Malaysian Rice Varieties.
Experiments were carried out in the laboratory and greenhouse to determine the growth inhibitory effects of Grassohopper's cyperus (Cyperus iria L.) on the seedlings of 5 Malaysian rice varieties namely MR211, MRQ74, MR220, MR84 and MR232. Three concentrations of the aqueous extract of the weed (12.5, 25.0 and 50.0 g/l) and weed debris (5, 10 and 20 g dry debris/1000 g soil) were used to test t...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Insect Vitellogenesis in Juvenile Hormone-dependent Species
In most insects, vitellogenesis is regulated by juvenile hormone (JH). The recent cloning of the vitellogenin gene in a number of JH-dependent species has allowed the study of the induction of vitellogenin production by JH at a molecular scale. Potential JH response elements have been described in the regulatory regions of vitellogenin and other JHinducible genes. These elements may not only sh...
