Efficient Agrobacterium-mediated Transformation of the Elite–Indica Rice Variety Komboka

[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 a new African variety Komboka using immature embryos. In Komboka, we obtained an apparent transformation rate of up to 48% for GUS/GFP reporter gene constructs using this optimized protocol. This ... [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]  A protocol for the axillary bud proliferation of prickly pear (Opuntia; Cactaceae) is presented. This genus is widely used as a crop in the arid and semi-arid areas of the globe worldwide, providing numerous benefits for human and animal consumption. In vitro culture for axillary bud proliferation is of great use to obtain a large quantity of plants in a short period of time, with potential uses in production and for the preservation of endangered species of the Opuntia genus.

The optimal medium for Opuntia in vitro culture consists of Murashige and Skoog medium (MS) and L2 vitamins. To increase the yield of the axillary bud proliferation, we recommend the addition of plant growth regulators (PGRs). This work suggests a 15 d incubation in the ...
[摘要]  提出了刺梨( Opuntia; Cactaceae )腋芽增殖的方案。 该属广泛用作全球干旱和半干旱地区的作物,为人类和动物消费提供了许多益处。 腋芽增殖的体外培养对于在短时间内获得大量植物具有重要意义,可用于生产和保存罂粟的濒危物种 属。

仙人掌体外培养的最佳培养基由Murashige和Skoog培养基(MS)和L2维生素组成。 为了增加腋芽增殖的产量,我们建议添加植物生长调节剂(PGRs)。 这项工作表明在含有2.2mg / L苄基氨基嘌呤(BA)的培养基中培养15天,然后将外植体转移到不含PGR的培养基中。 我们还解释了如何使植物适应体外条件。

【背景】仙人掌(刺梨)属是仙人掌科家族的成员之一(Bravo-Hollis,1978)。虽然它原产于美洲,但目前生长在欧洲南部,非洲北部,澳大利亚,中东,西亚和世界其他地区的野生和商业种植园中(Ochoa和Barbera,1995; Kiesling和Metzing) ,2017)。仙人掌对干旱和半干旱环境以及生活在这些地区的人类群落产生了深远的影响,因为尽管在干旱地区生长,其生物量仍然很高(Acevedo et al。,1983)。在许多这样的领域, Opuntia 属被用于许多方面。 仙人掌的幼枝可以作为蔬菜食用;水果直接食用或加工成果冻,果汁或糖果(Barba et ...

Shoot Regenerative Capacity Assays in Arabidopsis and Tobacco

[Abstract]  Plant regeneration refers to a process through which an explant is differentiated to a whole plant under certain conditions. It has been shown that two plant hormones, auxin and cytokinin, play critical roles within this process (Duclercq et al., 2011). Cytokinin induces shoot regeneration, whereas auxin promotes root production. In addition to hormones, recent study has revealed that age cue serves as a common element behind plant cell totipotency (Toledano et al., 2012). Here we present an easy protocol to assess the shoot regenerative capacity of Arabidopsis and tobacco leaves of different ages. [摘要]  植物再生是指在某些条件下外植体分化成整株植物的过程。 已经表明,两种植物激素,植物生长素和细胞分裂素在该过程中起关键作用(Duclercq等人,2011)。 细胞分裂素诱导芽再生,而生长素促进根生产。 除了激素,最近的研究已经揭示年龄提示作为植物细胞全能性背后的共同元素(Toledano等人,2012)。 在这里我们提出了一个简单的协议,以评估不同年龄的拟南芥和烟草叶的射线再生能力。
