    Visualization and Quantification of Cell-to-cell Movement of Proteins in Nicotiana benthamiana
    Authors:  Mila C Blekemolen, Mariliis Tark-Dame and Frank L.W Takken, date: 12/20/2018, view: 1877, Q&A: 0
    [Abstract] Cell-to-cell movement of proteins through plasmodesmata is a widely-established mechanism for intercellular signaling in plants. Current techniques to study intercellular protein translocation rely on single-cell transformation using particle bombardment or transgenic lines expressing photo-inducible fluorophores. The method presented here allows ...
    Generation and Selection of Transgenic Olive Plants
    Authors:  Elena Palomo-Ríos, Sergio Cerezo, Jose Ángel Mercado and Fernando Pliego-Alfaro, date: 11/20/2017, view: 3991, Q&A: 0
    [Abstract] Olive (Olea europaea L.) is one of the most important oil crops in the Mediterranean basin. Biotechnological improvement of this species is hampered by the recalcitrant nature of olive tissue to regenerate in vitro. In previous investigations, our group has developed a reliable Agrobacterium-mediated transformation ...
    Use of Geminivirus for Delivery of CRISPR/Cas9 Components to Tobacco by Agro-infiltration
    Authors:  Kangquan Yin, Ting Han and Yule Liu, date: 04/05/2017, view: 7583, Q&A: 0
    [Abstract] CRISPR/Cas9 system is a recently developed genome editing tool, and its power has been demonstrated in many organisms, including some plant species (Wang et al., 2016). In eukaryotes, the Cas9/gRNA complexes target genome sites specifically and cleave them to produce double-strand breaks (DSBs), which can be repaired by non-homologous end ...
    Multiplexed GuideRNA-expression to Efficiently Mutagenize Multiple Loci in Arabidopsis by CRISPR-Cas9
    Authors:  Julia Schumacher, Kerstin Kaufmann and Wenhao Yan, date: 03/05/2017, view: 6539, Q&A: 0
    [Abstract] Since the discovery of the CRISPR (clustered regularly interspaced short palindromic repeats)-associated protein (Cas) as an efficient tool for genome editing in plants (Li et al., 2013; Shan et al., 2013; Nekrasov et al., 2013), a large variety of applications, such as gene knock-out, knock-in or transcriptional ...
    Production of Guide RNAs in vitro and in vivo for CRISPR Using Ribozymes and RNA Polymerase II Promoters
    Authors:  Tao Zhang, Yangbin Gao, Rongchen Wang and Yunde Zhao, date: 02/20/2017, view: 9220, Q&A: 0
    [Abstract] CRISPR/Cas9-mediated genome editing relies on a guide RNA (gRNA) molecule to generate sequence-specific DNA cleavage, which is a prerequisite for gene editing. Here we establish a method that enables production of gRNAs from any promoters, in any organisms, and in vitro (Gao and Zhao, 2014). This method also makes it feasible to conduct ...
    Agrobacterium rhizogenes-Based Transformation of Soybean Roots to Form Composite Plants
    Authors:  Benjamin F. Matthews and Reham M. Youssef, date: 01/20/2016, view: 6432, Q&A: 0
    [Abstract] Transgenic soybean roots of composite plants are a powerful tool to rapidly test the function of genes and activity of gene promoters. No tissue culture is needed, thus avoiding loss of valuable material due to contamination. This is a simple technique that requires less training and care than tissue culture techniques. Furthermore, it takes less ...
    5’ Rapid Amplification of cDNA Ends (5’ RACE) of Agrobacterial T-DNA Genes within Transformed Plant Sample
    Author:  Yi Zhang, date: 09/20/2015, view: 7696, Q&A: 0
    [Abstract] The T-DNA (transferred-DNA) region of virulent Agrobacterium tumefaciens (A. tumefaciens) strain is transferred and integrated into the plant genome, and thereby the T-DNA genes are expressed in transformed plant cells. This protocol was used to analyze the transcription start sites (TSSs) of agrobacterial T-DNA genes within ...
    Transient Transformation of Artemisia annua
    Authors:  Dongming Ma and Hong Wang, date: 05/20/2015, view: 5103, Q&A: 0
    [Abstract] Transient transformation of Artemisia annua does not depend on chromosomal integration of heterologous DNA, and recombinant DNA can be introduced into plant cells via Agrobacterium aided by vacuum. The leaves of 7th and 8th internode from 4-week-old seedlings were chosen as explants, a vacuum system was applied to facilitate ...
    Agrobacterium-mediated Transformation of Mature Ginseng Embryos
    Authors:  Ok Ran Lee, Jin Haeng Han and Yoon-Ri Kim, date: 12/20/2014, view: 7625, Q&A: 0
    [Abstract] Ginseng refers to species within the genus Panax and is a slow-growing perennial herb from the Araliaceae family. The most widely used Panax species is Panax ginseng Meyer (Korean ginseng). Panax japonicus (Japanese ginseng), Panax notoginseng (Chinese ginseng), and Panax quinquefolium (American ...
    Agrobacterium tumefaciens-mediated Transformation of Walnut (Juglans regia)
    Authors:  Sriema L. Walawage, Charles A. Leslie, Matthew A. Escobar and Abhaya M. Dandekar, date: 10/05/2014, view: 8310, Q&A: 0
    [Abstract] Like many woody plant species, walnut (Juglans regia) can be difficult to genetically transform and regenerate. However, somatic embryos have been used successfully for over two decades as a target tissue for transformation and regeneration of transgenic walnut plants. Walnut somatic embryos, initiated originally from developing zygotic ...
