The influence of suppression of the expression of the Drosophila insulin-like receptor gene (InR) in corpus allatum (the gland-synthesizing juvenile hormone) on octopamine (OA) and juvenile hormone metabolism and on the development of the stress-reaction in Drosophila melanogaster females was studied. It was demonstrated that the suppression of InR gene(More)
Desulfurispirillum indicum strain S5, a novel obligate anaerobe belonging to the phylum Chrysiogenetes, is a dissimilatory selenate-, selenite-, arsenate-, nitrate- and nitrite-reducing bacterium. The circular genome of this metabolically versatile bacterium is 2.9 Mbp, with a G+C content of 56.1% and 2619 predicted protein-coding genes. Genome analysis(More)
The ability of anaerobic prokaryotes to employ different terminal electron acceptors for respiration enables these organisms to flourish in subsurface ecosystems. Desulfurispirillum indicum strain S5 is an obligate anaerobic bacterium that is able to grow by respiring a range of different electron acceptors, including arsenate and nitrate. Here, we examined(More)
Desulfurispirillum indicum strain S5(T) is a strictly anaerobic bacterium isolated from river sediment in Chennai, India. D. indicum belongs to the deep branching phylum of Chrysiogenetes, which currently only includes three other cultured species. Strain S5(T) is the type strain of the species and it is capable of growth using selenate, selenite, arsenate,(More)
Strain S5(T), a novel bacterium that was isolated for its capability to respire selenate to elemental selenium, is described. In addition to selenate respiration, it was also capable of dissimilatory selenite, arsenate and nitrate reduction with short-chain organic acids such as pyruvate, lactate and acetate as the carbon sources and electron donors. The(More)
dFOXO transcription factor is a component of the insulin/insulin-like growth factor signaling pathway in Drosophila. Juvenile hormone negatively regulates dFOXO gene expression. In the present work, the effect of hypomorphic dFOXO mutation on juvenile hormone metabolism under normal and stressing conditions and on D. melanogaster female resistance to(More)
263 It has long been established that the hormones that control insect development—juvenile hormone (JH) and 200hydroxyecdysone (20E)—play a gonadotropic role in the reproduction of adult insects (for review, see [1]). According to the model that is commonly accepted for Drosophila, JH synthesized de novo in a specialized endocrine gland, corpus allatum(More)
231 Numerous studies indicate that juvenile hormone (JH) plays a key role in the regulation of the reproducc tive function of female insects. Juvenile hormone is synthesized by the gland corpus allatum. It determines the sexual behavior of females, controls the synthesis of pheromones, induces the synthesis of ecdysteroids in the ovaries, and, together with(More)
A Gram-type-negative, obligately anaerobic, selenate-respiring bacterium, strain S4(T), was isolated from activated sludge of a wastewater treatment plant in New Jersey after enrichment with 10 mM selenate as the sole electron acceptor. In addition to its selenate-respiring capability, strain S4(T) also respired arsenate with acetate as carbon source and(More)
The effect of a decreased availability of the D1-like dopamine receptor (DopR) in Drosophila (caused by DopR antagonist added into food) on the juvenile hormone (JH) synthesis rate in young female D. melanogaster has been studied. The JH degradation rate and the alkaline phosphatase (ALP) and tyrosine decarboxylase (TDC) activities were used as indicators(More)
