Lepidopteran insects use sex pheromones derived from fatty acids in their species-specific mate recognition system. Desaturases play a particularly prominent role the generation of structural diversity lepidopteran pheromone biosynthesis as result diverse enzymatic properties they have evolved. These enzymes are homologous to integral membrane desaturases, which primary cold adaptation eukaryotic cells. In this investigation, we screened for desaturase-encoding sequences glands adult females...
Abstract In this study, we investigated the occurrence of aflatoxins (AFs) and ochratoxin A (OTA) in meju soybean paste produced South Korea. Samples were collected from three regions divided on basis climate total 100 samples analyzed over 3 years (2012–2015), 45 2016. Mycotoxins extracted with an immunoaffinity column method quantified by high-performance liquid chromatography. AFs detected 10 (10%) 11 (24.4%) concentrations 0.2–48.3 μg/kg 0.88–16.17 μg/kg, respectively. OTA was 50 (50%)...
Chitinase is a rate-limiting and endo-splitting enzyme involved in the bio-degradation of chitin, an important component cuticular exoskeleton peritrophic matrix insects. We isolated cDNA-encoding chitinase from last larval integument cabbage moth, Mamestra brassicae (Lepidoptera; Noctuidae), cloned ORF cDNA into E. coli to confirm its functionality, analyzed deduced amino acid sequence comparison with previously described lepidopteran chitinases. M. expressed transformed cells...
SUMMARY We investigated the effects of sap common oleander Nerium indicum (Apocyanaceae) on male fertility and spermatogenesis in oriental tobacco budworm Helicoverpa assulta. found that continuous feeding during larval period significantly affects males but not females. This effect was also induced by direct injection into hemocoel 2-day-old pupae. Histological analyses developing testes following revealed a developmental delay progressively more severe morphological abnormalities later...
Ornithine decarboxylase (ODC) is a rate-limiting enzyme in the biosynthesis of polyamines, which are essential for cell growth, differentiation, and proliferation. This report presents characterization an ODC-encoding cDNA (SlitODC) isolated from moth species, tobacco cutworm, Spodoptera litura (Lepidoptera); its expression polyamine-deficient strain yeast, S. cerevisiae; recovery polyamine levels proliferation rate with introduction insect enzyme. SlitODC encodes 448 amino acid residues, 4...
