Cytochrome P450 and UDP-glucosyltransferase (UGT) as phase I II metabolism enzymes, respectively, play vital roles in the breakdown of endobiotics xenobiotics. Insects can increase expression detoxification enzymes to cope with stress from xenobiotics including insecticides. However, molecular mechanisms for insecticide Spodoptera exigua remain elusive, genes conferring metabolisms this species are less well reported. In study, 68 32 UGT were identified. Phylogenetic analysis showed gene...
The evolution of insect resistance to insecticides is frequently associated with overexpression one or more cytochrome P450 enzyme genes. Although CYP450 genes a well-known mechanism insecticide resistance, the underlying regulatory mechanisms are poorly understood. Here we uncovered gene, CYP321A8 in major pest insect, Spodoptera exigua that resistant multiple insecticides. confers organophosphate (chlorpyrifos) and pyrethroid (cypermethrin deltamethrin) this insect. Constitutive...
Abstract BACKGROUND Glutathione S ‐transferases (GSTs) are a superfamily of multifunctional dimeric proteins existing in both prokaryotic and eukaryotic organisms. They involved the detoxification endogenous exogenous electrophiles, including insecticides. However, molecular mechanisms underlying regulation GST genes insects poorly understood. RESULTS We first identified at least three resistance to insecticides chlorpyrifos cypermethrin. Analysis upstream sequences revealed that GSTs (...
Frequent outbreaks and widespread transmission of rice black-streaked dwarf virus by Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) have aggravated yield losses in eastern China. The use insecticides for suppression the vector has been a fundamental approach to prevent epidemics disease. However, status insecticide resistance S. not examined recently In this study, dose responses buprofezin, imidacloprid, thiamethoxam, chlorpyrifos pymetrozine were evaluated. Most populations China...
Lethal infections are often associated with a specific dose threshold, where increasing inoculum size is an increased likelihood of death. However, quantitative explanation how this numeric threshold established lacking. For example, lethal thresholds may reflect at least one microbe can pass through host-imposed barriers to infection. Alternatively, failure the host immune system, leading numerous microbes initiating Here, using barcoded Streptococcus suis serotype 2 (SS2), we compare...
Acute respiratory distress syndrome (ARDS) is a critical pulmonary disorder with manifestations of edema, inflammation, and impaired oxygenation. Establishing reliable animal ARDS models has been for investigating its mechanisms testing pharmacological interventions. The present study sought to induce moderate model in New Zealand White rabbits involving mix lipopolysaccharide (LPS), oleic acid (OA), ventilation-induced lung injury (VILI). Four experimental groups were established: negative...
The rapid spread of extended-spectrum β-lactamases (ESBLs)-producing Escherichia coli (ESBL-EC) around the world has become a significant challenge for humans and animals. In this study, we aimed to examine characteristics horizontal gene transfer (HGT) capacity ESBL-EC derived from captive primates. We screened among total 444 multidrug-resistant (MDR) E. strains isolated 13 zoos in China using double-disk test. ESBL genes, mobile genetic elements (MGEs), virulence-associated genes (VAGs)...
Endo-dormant flower buds of tree peony must have sufficient chilling duration to reinitiate growth, which is a major obstacle the forcing culture in winter. We used combination two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionisation time flight/time flight mass spectrometry (MALDI-TOF/TOF MS) identify differentially expressed proteins after three different treatments: endo-dormancy, endo-dormancy release eco-dormancy stages. More than 200 highly...
Abstract Metaflumizone is a novel semicarbazone insecticide. It functions as sodium channel blocker insecticide (SCBI) with excellent insecticidal activity on most economically important lepidopterous pests. This study assessed the resistance risk of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) to metaflumizone in laboratory and effects selection toxicities other insecticides. collected from field population at Huizhou 2012 were successively challenged by evaluate evolution. Twelve...
Enhanced detoxification is one of the important mechanisms for insecticide resistance. Most research in this field to date has focused on role cytochrome P450s. Our previous work revealed that flavin-dependent monooxygenases (FMOs) were involved metabolic resistance Spodoptera exigua. In present study we investigated molecular characteristics, expression patterns and oxidative activities SeFMO insecticides. Three FMO genes, which encode proteins with typical motifs, cloned from S. The...
