文摘:生物入侵是不均衡世界的一個永恆話題,尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的,但另外一些則有著嚴重的後果,會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式,概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑,來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結,這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化(瓶頸效應及種群擴張) .最後,我們以歐洲櫟癭蜂(膜翅目,癭蜂科,癭蜂族)一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上,多態的等位酶位點上等位基因頻率的數據表明: 1 )遺傳多樣性沿入侵路線呈不斷下降的趨勢,支持了冰河期避難所作為遺傳多樣性中心的作用; 2 )入侵地區的種群與該物種原產地的種群相比,遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映Construction of male sterility expression vector by integration of artificial sense and antisense cdnas of hsp70 into puc18 and puc19 respectively, we can obtain psc and pac. tapertal specific expression promoter ta29 and terminator nos are connected directionally with sense and antisense cdnas of hsp70 extrected and purified from psc and pac., then integrated into puc18 and puc19, by which we can build sense and antisense cdna nos ( respectively named plasmid 650 and plasmid 651 ) of ta29 - hsp70. for the sake of better screening and examination of transformed gene, we cut plasmid 650, plasmid 651 and 3301 ( containing gusgene bar screening marker gene ) with hindiii and ecor i enzymes, then connect purified fragments of 650and 651 with plasmid 3301 to construct the vector 3301 + 650 and 3301 + 651. corroboration of whether sense and antisense cdna - nos is integrated into plasmid3301 can be made by plate screening and enzye - cutting analysis
