傳標誌在蟎蜱（Acari）系統學上之應用

Application of Genetic Markers for the Phylogenetic of Acari

"傳統蟎蜱種類鑑定，多以成熟體的外部形態作為鑑定的依據，但由於體型小或因分類特徵不穩定或不明顯，而難以準確鑑定種類。以遺傳標誌（genetic markers）應用於蟎蜱系統學，既可進行種群類緣關係分析，並可運用於蟎蜱遺傳演化研究。目前運用於蟎蜱之遺傳標誌，如：核醣體DNA（ribosomal DNA, rDNA）、粒線體DNA（mitochondrial DNA, mtDNA）、微衛星DNA（microsatellite DNA）、限制酵素片段多態型（restriction fragment length polymorphism, RFLP）、直接擴增酵素多態型（direct amplification of length polymorphism, DALP）、擴增片段長度多形性（amplified fragment length polymorphism, AFLP）、逢機擴增DNA片段多形性（random amplified polymorphic DNA, RAPD）、等位基因酶（allozymes）。"

Application of genetic markers on study of acarology can identify the phylogenetic relationship of different populations of mites and ticks. The vast diversity of mites makes them particularly suitable for these kinds of stuides. The genetic methods used to study these organisms include ribosomal DNA, mitochondrial DNA, microsatellites, restriction fragment length polymorphism (RFLP), direct amplification of length polymorphism (DALP), amplified fragment length polymorphism (AFLP), random amplified polymorphic DNA (RAPD), and allozymes.
