  接合 conjugation
  是原生动物纤毛虫类的有性生殖方法。交合时,是两个配子结合产生一个合子,而接合则是一度接合在一起的两个个体分离而成为与原来相同的两个个体。参与接合的两个个体称为接合体(conjug-ant)。例如草履虫(Paramecium caudatum),两接合体以围口部相互吻合,各自的大核解体而消失,小核分裂两次而成四个,其中三个消失而剩下一个核(相当于减数分裂),这个核再次分裂为二。一个作为休眠核留在原来的接合体中,另一个作为游走核经接合部互相移进对方个体,即进行游走核的交换。这样,两接合体内的休眠核和游走核的接合形成接合核后,两个个体就分离了。通常接合体的双方,其形状和大小均相同的,称为同形接合(例草履虫),但是头巾斜虫(Chilodon cucullulus)等的两接合体之大小稍有差别,而缘毛类的钟虫(Vorticella)、独宿虫(Carchesium)等,两接合体的大小差异明显,所以称为异形接合。尾棘(纤)虫(Stylonychia)扭头(纤)虫(Metopus)等,接合时两个个体有时合并成一个个体,特称之为全接合(total conjuga-tion)。钟虫与尾棘虫,扭头虫较相似。接合核只产生于大接合体(macroconjugant,正常的个体),而小接合体(micorconjugant,由正常个体分裂而产生,在缺柄的体后部有纤毛环)内的休眠核和游走核随同大部分细胞质被大接合体吸收,因为残余部分解体和消失,所以几乎等于合体。只有反复无性二分裂会使细胞衰老,因此认为接合可以使细胞复壮,进行返老还童(比奇利O.Butschli、毛帕斯Maupas、卡尔金斯G.N.Calkins、李·海特维希R.Hertwig),但是伍德拉夫、L.L.Woodruff曾经使双小核草履虫(Pa-ramecium aurelia)不经过接合连续繁殖8400代(但包括内合)。在接合中两接合体之间进行遗传物质的交换,这一点与内合不同。
  接合是通过性菌毛互相沟通,将遗传物质(主要是质粒DNA)从供体菌转移给受体菌.

  接合
  connex
    单细胞生物有性生殖过程中的一种生殖形式(现象)。同一物种中属于不同接合型的细胞连接在一起,并交换遗传物质。在大肠杆菌中,DNA的转移是单向的;在草履虫则是相互的。
