    Design and Direct Assembly of Synthesized Uracil-containing Non-clonal DNA Fragments into Vectors by USERTM Cloning
    [Abstract] This protocol describes how to order and directly assemble uracil-containing non-clonal DNA fragments by uracil excision based cloning (USER cloning). The protocol was generated with the goal of making synthesized non-clonal DNA fragments directly compatible with USERTM cloning. The protocol is highly efficient and would be compatible ...
    Trimolecular Fluorescence Complementation (TriFC) Assay for Direct Visualization of RNA-Protein Interaction in planta
    Authors:  Jun Sung Seo and Nam-Hai Chua, date: 10/20/2017, view: 424, Q&A: 0
    [Abstract] RNA-Protein interactions play important roles in various eukaryotic biological processes. Molecular imaging of subcellular localization of RNA/protein complexes in plants is critical for understanding these interactions. However, methods to image RNA-Protein interactions in living plants have not yet been developed until now. Recently, we have ...
    Analysis of Xyloglucan Composition in Arabidopsis Leaves
    Authors:  Javier Sampedro, Cristina Gianzo, Esteban Guitián, Gloria Revilla and Ignacio Zarra, date: 10/05/2017, view: 438, Q&A: 0
    [Abstract] Xyloglucan is one of the main components of the primary cell wall in most species of plants. This protocol describes a method to analyze the composition of the enzyme-accessible and enzyme-inaccessible fractions of xyloglucan in the model species Arabidopsis thaliana. It is based on digestion with an endoglucanase that attacks ...
    Ensifer-mediated Arabidopsis thaliana Root Transformation (E-ART): A Protocol to Analyse the Factors that Support Ensifer-mediated Transformation (EMT) of Plant Cells
    Authors:  Dheeraj Singh Rathore, Fiona M. Doohan and Ewen Mullins, date: 10/05/2017, view: 461, Q&A: 0
    [Abstract] Ensifer adhaerens OV14, a soil borne alpha-proteobacteria of the Rhizobiaceae family, fortifies the novel plant transformation technology platform termed ‘Ensifer-mediated transformation’ (EMT). EMT can stably transform both monocot and dicot species, and the host range of EMT is continuously expanding across a diverse range of ...
    Detection of Protein S-nitrosothiols (SNOs) in Plant Samples on Diaminofluorescein (DAF) Gels
    Authors:  Marta Rodríguez-Ruiz, Paulo T. Mioto, José M. Palma and Francisco J. Corpas , date: 09/20/2017, view: 579, Q&A: 0
    [Abstract] In plant cells, the analysis of protein S-nitrosothiols (SNOs) under physiological and adverse stress conditions is essential to understand the mechanisms of Nitric oxide (NO)-based signaling. We adapted a previously reported protocol for detecting protein SNOs in animal systems (King et al., 2005) for plant samples. Briefly, ...
    Construction of a Single Transcriptional Unit for Expression of Cas9 and Single-guide RNAs for Genome Editing in Plants
    Authors:  Xu Tang, Zhaohui Zhong, Xuelian Zheng and Yong Zhang, date: 09/05/2017, view: 923, Q&A: 0
    [Abstract] The CRISPR (clustered regularly interspaced short palindromic repeats)-associated protein9 (Cas9) is a simple and efficient tool for genome editing in many organisms including plant and crop species. The sgRNAs of the CRISPR/Cas9 system are typically expressed from RNA polymerase III promoters, such as U6 and U3. In many transformation events, ...
    Isolation and Quantification of Plant Extracellular Vesicles
    Authors:  Brian D. Rutter, Katie L. Rutter and Roger W. Innes, date: 09/05/2017, view: 1000, Q&A: 0
    [Abstract] Extracellular vesicles (EVs) play an important role in intercellular communication by transporting proteins and RNA. While plant cells secrete EVs, they have only recently been isolated and questions regarding their biogenesis, release, uptake and function remain unanswered. Here, we present a detailed protocol for isolating EVs from the ...
    Ubiquitin Proteasome Activity Measurement in Total Plant Extracts
    Authors:  Suayib Üstün and Frederik Börnke, date: 09/05/2017, view: 711, Q&A: 0
    [Abstract] The fine-tuned balance of protein level, conformation and location within the cell is vital for the dynamic changes required for a cell to respond to a given stimulus. This requires the regulated turnover of damaged or short-lived proteins through the ubiquitin proteasome system (UPS). Thus, the protease activity of the proteasome is adjusted to ...
    [Bio101] Leaf Clearing Protocol to Observe Stomata and Other Cells on Leaf Surface
    Author:  Nidhi Sharma, date: 09/05/2017, view: 634, Q&A: 0
    [Abstract] In this protocol, leaves are cleared and fixed in an ethanol and acetic acid solution, and mounted in Hoyer’s solution. The cleared leaves are imaged under differential interference contrast (DIC) microscope. This protocol is beneficial for studying stomata, hair cells, and other epidermal cells in plants.
    Using Silicon Polymer Impression Technique and Scanning Electron Microscopy to Measure Stomatal Aperture, Morphology, and Density
    Authors:  Hui-Chen Wu, Ya-Chen Huang, Chia-Hung Liu and Tsung-Luo Jinn, date: 08/20/2017, view: 763, Q&A: 0
    [Abstract] The number of stomata on leaves can be affected by intrinsic development programming and various environmental factors, in addition the control of stomatal apertures is extremely important for the plant stress response. In response to elevated temperatures, transpiration occurs through the stomatal apertures, allowing the leaf to cool through ...
