[Abstract]  Genetic transformation is crucial for both investigating gene functions and for engineering of crops to introduce new traits. Rice (Oryza sativa L.) is an important model in plant research, since it is the staple food for more than half of the world’s population. As a result, numerous transformation methods have been developed for both indica and japonica rice. Since breeders continuously develop new rice varieties, transformation protocols have to be adapted for each new variety. Here we provide an optimized transformation protocol with detailed tips and tricks for ... [摘要]  
[摘要 ] 遗传转化对于研究基因功能和农作物工程引入新性状均至关重要。水稻(Oryza sativa L.)是植物研究中的重要模型,因为它是世界一半以上人口的主食。其结果是,大量的转化方法已经开发了两个籼稻和粳稻米。由于育种者不断开发新的水稻品种,因此必须针对每个新品种适应转化方案。在这里,我们为使用未成熟胚的非洲新品种Komboka 提供了一种优化的转化协议,包括详细的技巧和窍门。在Komboka中,我们使用此优化方案对GUS / GFP报告基因构建体的表观转化率高达48%。该协议也适用于其他优质lite 稻品种。


[背景 ] 为植物的遗传转化的各种方法公顷一直在开发,例如穿孔(Shimamoto PEG介导的原生质体转染。等人,1989;达塔。等人,1992),生物射弹转化(Christou的等人,1991)和农杆菌-介导的转化(Slamet-Loedin 等,2014)。农杆菌介导的转化是将DNA引入植物的最广泛使用的方法之一(van Wordragen and Dons,1992)。该方法已被广泛用于研究,并已成为生物技术的关键先决条件。自从开发新的育种技术(如基因组编辑)以来,它就变得越来越重要(Char ...

[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; ...

Detection of Mitogen-activated Protein Kinase (MAPK) Activation upon Exogenous Chemical Application in Arabidopsis Protoplasts

[Abstract]  The mitogen activated protein kinase cascade is a highly conserved signal pathway in plants. The exogenous chemicals, like hormones, can trigger a series of signalling cascades, including MAPK pathway, to modulate the plant physiology. Upon activation, some MAPKs are phosphorylated. It is important to develop methods that can detect changes in the phosphorylation status of MAPKs in plants when they come in contact with external chemicals. This method describes the exogenous treatment of Arabidopsis protoplasts with Kinetin and subsequent detection of the activated MAPKs. This method ... [摘要]  丝裂原活化蛋白激酶级联是植物中高度保守的信号通路。 外源化学物质,如激素,可以触发一系列信号级联,包括MAPK途径,以调节植物生理。 在激活时,一些MAPK被磷酸化。 开发能够检测植物中MAPK在与外部化学品接触时磷酸化状态的变化的方法是重要的。 该方法描述了用激动素对随后检测激活的MAPK的拟南芥原生质体的外源处理。 该方法可用于研究外源施加的化合物对拟南芥中MAPK信号级联的影响。
