Malaria, tuberculosis, and AIDS are three major pathogen-specific causes of human mortality in the world. More than 90% of the world's malaria is in Africa, where the mosquito Anopheles gambiae is the primary vector. Human and malaria parasite genome projects are now underway and expected to be complete within the next year or two. This proposal seeks to initiate an A.gambiae genome project, with the expectation that the availability of the genomes of the parasite, human host, and the vector will lead to the development of novel malaria control strategies. The immediate aims of this proposal are the following: (1)to sequence 10,000 ESTs from normalized cDNA libraries made from each of five different mosquito tissues (salivary gland, midgut, fatbody, head, and immune- responsive cell lines), (2) to physically map to the mosquito's polytene chromosomes 2,000 genomic DNA Bacterial Artificial Chromosomes (BACs), (3) to sequence both ends of 25,000 genomic DNA BACs, and (4) to assess local scale synteny between the mosquito and Drosophila melanogaster by sequencing 3 megabases of sequence selected to be homologous with the well studied D. melanogaster Adh region. These 4 aims will provide sequences for direct gene discovery, for gene expression analysis (by microarray techniques), and for the determination of broad (polytene chromosome level) and local (megabase sequence level) synteny between D .melanogaster and A. gambiae. They will also facilitate a subsequent full genome sequencing project, either by a Sequence Tagged Connector strategy or by a shotgun strategy. The project is structured to involve the participation of both US and European institutions so as to make this an international effort. The long range is to encourage a broad range of funding agencies to join in supporting an effort to sequence the entire genome of this mosquito.

疟疾、结核病和艾滋病是世界上人类死亡的三大特定病原体原因。世界上90%以上的疟疾发生在非洲，冈比亚按蚊是非洲的主要媒介。人类和疟疾寄生虫基因组计划目前正在进行中，预计将在未来一两年内完成。这项提议旨在启动冈比亚按蚊基因组项目，期望获得寄生虫、人类宿主和媒介的基因组将导致开发新的疟疾控制策略。该建议的直接目标如下：(1)从五种不同蚊子组织(唾液腺、中肠、脂肪体、头部和免疫反应细胞系)的归一化cDNA文库中对10,000个EST进行测序；(2)将其物理定位到蚊子的多线染色体2,000个基因组DNA细菌人工染色体(BAC)；(3)对25,000个基因组DNA BAC的两端进行测序；以及(4)通过对选定的与黑腹果蝇adh区同源的3个百万碱基的序列进行测序来评估蚊子和果蝇之间的局部同源性。这4个AIMS将为直接基因发现、基因表达分析(通过微阵列技术)以及确定黑腹隐翅虫和冈比亚按蚊之间的广泛(多线染色体水平)和局部(百万碱基序列水平)同步性提供序列。它们还将促进后续的全基因组测序项目，无论是通过序列标记连接器策略还是通过猎枪策略。该项目的结构包括美国和欧洲机构的参与，以使其成为一项国际努力。长远的目标是鼓励广泛的资助机构加入支持对这种蚊子的整个基因组进行测序的努力。
