Effective control of Anopheles minimus s.l., an important malaria vector in Southeast Asia, is based on the accurate identification of species within An. minimus complex, which cannot be distinguished using morphological characters. Derived from individual random amplified polymorphic DNA markers, sequence characterized amplified regions were analysed for the design of species-specific paired-primers. Combination of these primers resulted in the development of a simple, robust multiplex PCR able to identify both species An. minimus A and C belonging to the complex, hybrids AC, and three sympatric and closely related species, An. aconitus, An. pampanai and An. varuna. Hybrids AC do not possess alleles of both parents but exhibit novel adaptive potentials resulting from recombination among parental genes leading to hybrizyme.
微小按蚊(Anopheles minimus s.l.)是东南亚一种重要的疟疾传播媒介,对其有效控制基于准确鉴定微小按蚊复合体中的物种,而这些物种无法通过形态特征加以区分。从个体随机扩增多态性DNA标记衍生而来的序列特征扩增区域,被用于分析以设计物种特异性配对引物。这些引物的组合促成了一种简单、稳健的多重聚合酶链反应(PCR)的开发,该反应能够鉴定复合体中的微小按蚊A和C物种、AC杂交种,以及三种同域分布且亲缘关系密切的物种,即乌头按蚊(An. aconitus)、潘氏按蚊(An. pampanai)和瓦氏按蚊(An. varuna)。AC杂交种并不拥有双亲的等位基因,而是展现出由亲本基因间重组导致杂交酶产生的新的适应潜力。
