Research on gene expression in mosquitoes is motivated by both basic and applied interests. Studies of genes involved in hematophagy, reproduction, olfaction, and immune responses reveal an exquisite confluence of biological adaptations that result in these highly-successful life forms. The requirement of female mosquitoes for a bloodmeal for propagation has been exploited by a wide diversity of viral, protozoan and metazoan pathogens as part of their life cycles. Identifying genes involved in host-seeking, blood feeding and digestion, reproduction, insecticide resistance and susceptibility/refractoriness to pathogen development is expected to provide the bases for the development of novel methods to control mosquito-borne diseases. Advances in mosquito transgenesis technologies, the availability of whole genome sequence information, mass sequencing and analyses of transcriptomes and RNAi techniques will assist development of these tools as well as deepen the understanding of the underlying genetic components for biological phenomena characteristic of these insect species.
对蚊子基因表达的研究既受基础研究兴趣的驱动,也受应用研究兴趣的驱动。对参与吸血、繁殖、嗅觉和免疫反应的基因的研究揭示了生物适应性的精妙融合,正是这种融合造就了这些极其成功的生命形式。雌性蚊子为了繁殖需要吸食血液,这已被各种各样的病毒、原生动物和后生动物病原体在其生命周期中加以利用。鉴定参与寻找宿主、吸血与消化、繁殖、抗杀虫剂以及对病原体发育的易感性/难治性的基因,有望为开发控制蚊媒疾病的新方法提供依据。蚊子转基因技术的进展、全基因组序列信息的可得性、转录组的大规模测序与分析以及RNA干扰技术,将有助于这些工具的开发,并加深对这些昆虫物种所特有的生物现象的潜在遗传成分的理解。
