  1. A novel calcium-independent cellular PLA2 acts in insect immunity and larval growth

    Insect Biochemistry and Molecular Biology 66:13 (2015)

    Phospholipase A2 (PLA2) catalyzes the position-specific hydrolysis of fatty acids linked to the sn-2 position of phospholipids (PLs). PLA2s make up a very large superfamily, with more than known 15 groups, classified into secretory PLA2 (sPLA2), Ca2+-dependent cellular PLA2 (sPLA2) and...
  2. A single nucleotide change in a core promoter is involved in the progressive overexpression of the duplicated CYP9M10 haplotype lineage in Culex quinquefasciatus

    Insect Biochemistry and Molecular Biology 66:96 (2015)

    Although the importance of cis-acting mutations on detoxification enzyme genes for insecticide resistance is widely accepted, only a few of them have been determined as concrete mutations present in genomic DNA till date. The overexpression of a cytochrome P450 gene, CYP9M10, is associ...
  3. Misdirection of dosage compensation underlies bidirectional sex-specific death in Wolbachia-infected Ostrinia scapulalis

    Insect Biochemistry and Molecular Biology 66:72 (2015)

    Endosymbiotic bacteria of the genus Wolbachia often manipulate the reproductive system of their hosts to propagate themselves in host populations. Ostrinia scapulalis moths infected with Wolbachia (wSca) produce female-only progeny (sex chromosomes: ZW), whereas females cured of the in...
  4. Towards an understanding of the structural basis for insect olfaction by odorant receptors

    Insect Biochemistry and Molecular Biology 66:31 (2015)

    Insects have co-opted a unique family of seven transmembrane proteins for odour sensing. Odorant receptors are believed to have evolved from gustatory receptors somewhere at the base of the Hexapoda and have expanded substantially to become the dominant class of odour recognition eleme...
  5. Odorant receptor-based discovery of natural repellents of human lice

    Insect Biochemistry and Molecular Biology 66:103 (2015)

    The body louse, Pediculus humanus humanus, is an obligate blood-feeding ectoparasite and an important insect vector that mediates the transmission of diseases to humans. The analysis of the body louse genome revealed a drastic reduction of the chemosensory gene repertoires when compare...
  6. Differential interactions of 5-(4-piperidyl)-3-isoxazolol analogues with insect γ-aminobutyric acid receptors leading to functional selectivity

    Insect Biochemistry and Molecular Biology 66:64 (2015)

    γ-Aminobutyric acid (GABA) receptors (GABARs) mediate fast inhibitory synaptic transmission and are also targets for drugs and insecticides. To better understand the molecular interactions of ligands with the orthosteric sites of GABARs, we examined 4-aryl/arylalkyl-5-(4-piperidyl)-3-i...
  7. A reference gene set for chemosensory receptor genes of Manduca sexta

    Insect Biochemistry and Molecular Biology 66:51 (2015)

    The order of Lepidoptera has historically been crucial for chemosensory research, with many important advances coming from the analysis of species like Bombyx mori or the tobacco hornworm, Manduca sexta. Specifically M. sexta has long been a major model species in the field, especially...
  8. Molecular characterization of the gene feminizer in the stingless bee Melipona interrupta (Hymenoptera: Apidae) reveals association to sex and caste development

    Insect Biochemistry and Molecular Biology 66:24 (2015)

    In highly eusocial insects, development of reproductive traits are regulated not only by sex determination pathway, but it also depends on caste fate. The molecular basis of both mechanisms in stingless bees and possible interaction with each other is still obscure. Here, we investigat...
  9. BmBR-C Z4 is an upstream regulatory factor of BmPOUM2 controlling the pupal specific expression of BmWCP4 in the silkworm, Bombyx mori

    Insect Biochemistry and Molecular Biology 66:42 (2015)

    20-hydroxyecdysone (20E)-induced expression of the wing disc cuticle protein gene BmWCP4 was mediated by the transcription factor BmPOUM2, which binds to the cis-response elements (CREs) of BmWCP4 gene in Bombyx mori. In this study we report the regulation of BmPOUM2. RT-PCR analysis i...
  10. A salivary sheath protein essential for the interaction of the brown planthopper with rice plants

    Insect Biochemistry and Molecular Biology 66:77 (2015)

    Salivary secretions, including gel saliva and watery saliva, play crucial roles in the interaction between the insect and plant during feeding. In this study, we identified a salivary gland-specific gene encoding a salivary sheath protein (NlShp) in Nilaparvata lugens. NlShp has two al...
