Project description:Culex pipiens molestus and Cx. p. quinquefasciatus are the members of Culex pipiens Complex, but they display relatively large differences in behavior and physiological responses. We compared the genes of these mosquitoes to identify those that were differentially expressed in each subspecies. Such genes could play important roles in subspecies-specific blood feeding or oviposition behavior. Culex pipiens molestus and Cx. p. quinquefasciatus females were undertaken Illumina RNA sequencing.

Project description:Culex pipiens pallens and Cx. p. quinquefasciatus are important vectors of many diseases, such as West Nile fever and lymphatic filariasis. The widespread use of insecticides to control these disease vectors and other insect pests has led to insecticide resistance becoming common in these species. High throughput screening using SSH and specific microarray platforms was thought to have identified some resistance-related genes. However, limitations of these methods meant that only a few hundred of the many thousand genes could be screened. It wasn’t until the sequencing of the Cx. quinquefasciatus genome in 2010 that it became possible to screen all 18.9 thousand genes in the mosquito genome for anti-insecticidal activity. We used high throughout Illumina sequencing to identify hundreds of Cx. p. pallens and Cx. p. quinquefasciatus genes that were differentially expressed in response to pesticide exposure. The identification of these genes is a vital first step for more detailed investigation of the molecular mechanisms involved in insecticide resistance in mosquitoes. In this study, larvae of Cx. pipiens pallens and Cx. pipiens quinquefasciatus were collected from field and transported to the laboratory and reared to adulthood to get F1 generation. Then, half of the F1 generation was conducted to pesticide bioassay. RNA extraction and Illumina sequencing were undertaken in another half of the F1 generation. Therefore, Samples used in Illumina sequencing did not contact any insecticides. Twelve Cx. pipiens pallens and Cx. pipiens quinquefasciatus lavae were undertaken Illumina RNA sequencing.

Project description:Investigation of gene expression level differences in Culex pipiens (SB) and C. quinquefasciatus (JHB) at three time points (8, 16, and 24 hours post-exposure) during the early pupal state in standard (25°C; 16 h light/8 h dark) and diapause-inducing (18°C; 8 h light/16 h dark) conditions. A forty-eight chip study (4 Expr12x135K slides) using cDNA from total RNA collected from two species in the Culex pipiens complex at 3 time-points during the early pupal stage to study gene expression differences between standard (25°C; 16 h light/8 h dark) and diapause-inducing (18°C; 8 h light/16 h dark) conditions, and between Culex pipiens (diapause) and C. quinquefasciatus (no diapause). Each chip measures the expression level of 18,692 protein coding genes, with 3 probes per gene and two-fold technical redundancy. Each of the 12-plex slides was used for one of four biological replicates. Probes were designed using the C.quinquefasciatus CpipJ1.2 geneset in VectorBase.

Project description:The genomes of three major mosquito vectors of human diseases, including Anopheles gambiae, Aedes aegypti, and Culex pipiens quinquefasciatus, have been previously sequenced. C. p. quinquefasciatus has the largest number of predicted protein-coding genes, which partially results from the expansion of three detoxification gene families: cytochrome P450 monooxygenases (P450), glutathione S-transferases (GST), and carboxylcholinesterases (CCE). However, unlike A. gambiae and A. aegypti, which have large amounts of gene expression data, C. p. quinquefasciatus has limited transcriptomic resources. Knowledge of complete gene expression information is very important for the exploration of the functions of genes involved in specific biological processes. In the present study, the three detoxification gene families of C. p. quinquefasciatus were analyzed for phylogenetic classification and compared with those of three other dipteran insects. Gene expression during various developmental stages and the differential expression responsible for parathion resistance were profiled using the digital gene expression (DGE) technique. Results: A total of 291 detoxification genes were found in C. p. quinquefasciatus, including 70 CCE, 186 P450, and 35 GST genes. Compared with three other dipteran species, gene expansion in Culex mainly occurred in the CCE and P450 families, where the genes of α-esterases, juvenile hormone esterases, and CYP325 of the CYP4 subfamily showed the most pronounced expansion on the genome. A total of 13314 genes were expressed in five DGE libraries. Genes with signal transduction and odorant binding functions were prominently expressed during egg development. Genes involved in proteolysis, glycosphingolipid biosynthesis, and purine metabolism were preferentially expressed at the larval stage. Seventy five percent of the detoxification genes were found to be expressed. One fourth of the CCE and P450 genes were expressed at unique stages, indicating their developmentally regulated expression. Fifteen detoxification genes, including 2 CCEs, 6 GSTs, and 7 P450s, were expressed at higher levels in a parathion-resistant strain than in a susceptible strain. Conclusion: The results of the present study provide new insights into the functions and evolution of three detoxification gene families in mosquitoes and comprehensive transcriptomic resources for C. p. quinquefasciatus, which will facilitate the elucidation of molecular mechanisms underlying the different biological characteristics of the three major mosquito vectors.
