Electro-fusion of Gametes and Subsequent Culture of Zygotes in Rice

[Abstract]  Electro-fusion system with isolated gametes has been utilized to dissect fertilization-induced events in angiosperms, such as egg activation, zygote development and early embryogenesis, since the female gametophytes of plants are deeply embedded within ovaries. In this protocol, procedures for isolation of rice gametes, electro-fusion of gametes, and culture of the produced zygotes are described. [摘要]  已经利用具有孤立配子的电融合系统来解剖被子植物中受精诱导的事件,例如卵活化,合子发育和早期胚胎发生,因为植物的雌配子体深深嵌入卵巢内。在该方案中,描述了分离水稻配子,配子电融合和产生的受精卵培养的程序。

背景 被子植物的受精和后续事件,如胚胎发生和胚乳发育,发生在深入嵌入卵母细胞的胚囊中(Nawaschin,1898; Guignard,1899; Russell,1992; Raghavan,2003)。因此,分离的配子已被用于体外受精(IVF)系统,以观察和分析受精和后处理过程(Wang等人,2006年)。用于被子植物的IVF系统包括三种基本微技术的组合:(i)男性和女性配子的分离和选择; (ii)配对对和(iii)单细胞培养物的融合(Kranz,1999)。已经在广泛的植物物种中建立了分离活的配子的程序,包括单子叶植物和双子叶植物(综述于Kranz,1999和Okamoto,2011)。分离的配子可以电融合(Kranz等人,1991; Uchiumi等人,2006和2007)或化学地使用钙(Faure等人,1994; Kranz和Lörz,1994; Khalequzzaman和Haq,2005),聚乙二醇(Sun等,1995; ...

Preparation of Knockdown Transformants of Unicellular Charophycean Alga, Closterium peracerosum-strigosum-littorale Complex

[Abstract]  To prepare the knockdown transformants of the Closterium peracerosum-strigosum-littorale (C. psl.) complex, particle bombardment was applied with a newly constructed vector (pSA0104) with an endogenous constitutive promoter fused to a DNA fragment corresponding to an antisense strand of a target gene. Using a hygromycin resistance gene (aph7”), hygromycin-resistant colonies were selected. After the second screening, integration of the vector into the genome was checked by PCR and the knockdown effect was evaluated by Western blotting using a specific antibody ... [摘要]  为了制备鬼臼藓藻(Clonsterium peracerosum-strigosum-littorale)复合物的敲低转化体,用新构建的载体(pSA0104)应用粒子轰击,所述载体具有内源性 组成型启动子,其与对应于靶基因的反义链的DNA片段融合。 使用潮霉素抗性基因( aph7")选择潮霉素抗性菌落。 在第二次筛选后,通过PCR检查载体到基因组中的整合,并使用针对靶蛋白的特异性抗体通过蛋白质印迹评估敲低效应。
