   本研究經(jīng)用54種隨機(jī)引物對57種蟋蟀的rapd擴(kuò)增分析得出以下結(jié)論： 1 ）采用rapd技術(shù)，首次較系統(tǒng)地對中國蟋蟀總科7科26屬共57種蟋蟀進(jìn)行了系統(tǒng)學(xué)研究。在所試用的54種隨機(jī)引物中篩選出可擴(kuò)增出清晰可辨且穩(wěn)定的rapd圖譜的引物分別為：蟋蟀科9種、嶺蟋科9種、樹蟋科12種、結(jié)蟋科12種、蛛蟋科13種、鐵蟋科13種、貌蟋科13種。
4. Rapd ( random amplified polymorphic dna ) , which bases on the polymerase chain reaction ( pcr ) , is by far one of the most commonly molecular techniques to uncover dna sequence polymorphisms . the basic priciple of this technique is that an arbitrary primer ( usually lobp oligonudetide ) is used to amplify random segments of dna , and a small number of fragments will be amplified when the primer anneals on each strand over a length range . if sequence variation is present at the priming site , then a fragment may not be amplied , so the dna polymorphic can be detected
   Rapd (隨機(jī)擴(kuò)增多態(tài)性dna )技術(shù)是二十世紀(jì)90年代發(fā)展起來的一項dna分子多態(tài)性檢測技術(shù)，它建立于聚合酶鏈?zhǔn)椒磻?yīng)( pcr )技術(shù)基礎(chǔ)之上，利用隨機(jī)合成的寡聚核苷酸序列為引物(一般為10個bp ) ，分別與dna的兩條單鏈結(jié)合，在dna聚合酶的作用下，對基因組的特定區(qū)域進(jìn)行pcr擴(kuò)增，其電泳結(jié)果為不同大小和數(shù)目的dna譜帶即rapd圖譜，可反映基因組相應(yīng)區(qū)域的dna多態(tài)性。
5. Forty arbitrary primers were used in the analysis of the seven samples , within which five primers produced relatively stable diversity . in total 49 loci were detected by these five primers , including 25 diverse loci ( 51 % ) . pairwise genetic distances were calculated and accordingly cluster analysis was carried out and the genetic dendrogram of the seven samples were generated
